A low temperature Nitrile compound for use in applications where sealability
at lower temperatures is important. Due to the lower acrylonitrile content, this
compound will show slightly less resistance to petroleum products.
This is a hydrogenated Nitrile compound which provides the material with
improved resistance to heat, ozone and aging. Similar applications to Nitrile but
with improved mechanical properties and media resistance. Excellent for many
oilfield and automotive applications. H2S resistance up to 10%.

O-Ring Design Guide
O-Ring Cross-Section
The I.D. and O.D. of an O-ring gland is primarily influenced by diameter of the mating surface of the rod or piston and bore.
Although the cross-section of the O-ring is seen as fairly arbitrary, there are some distinct advantages to either a larger or smaller
cross-section O-ring. Listed below are the advantages of small cross-sections and the advantages of large cross-sections:
Advantages of Smaller Cross-Section
•
•
•
•
•
Advantages of Larger Cross-Section
More compact
Lighter weight
Less expensive; especially for higher cost elastomers like
FKM or fluorosilicone
Less machining required for machined grooves since
grooves are smaller
More resistant to explosive decompression
•
•
•
•
Less prone to compression set
Less volume swell in liquid on a percentage basis
Allows for larger tolerance while still maintaining
acceptable compression squeeze and compression ratio
over full stack-up range
Less prone to leakage due to contamination; dirt, lint,
scratches, etc.
O-Ring Gland Types
O-rings are primarily used to prevent the loss of a fluid or gas. However, O-rings can be used as dust seals, drive belts or on
rotating shafts. Most O-ring seals can be classified into one of the three arrangements shown below.

I.D. Stretch/O.D. Interference
For hydraulic and pneumatic piston sealing applications
The O-ring inside diameter (I.D.) should be stretched between 2% and 5% for dynamic applications and 2% and 8% for static
applications. For O-rings with an inside diameter smaller than 20 mm, this is not always possible which can result in a wider
range of stretch. To minimize this range and the maximum stretch, it is necessary to minimize the tolerance of the piston gland
diameter, and have a less stringent requirement for the minimum O-ring stretch. In dynamic applications, it is important to keep
the maximum stretch to 5% or less to avoid detrimental effects on sealing performance.
For hydraulic and pneumatic rod sealing applications
The O-ring's outside diameter (O.D.) should be at least equal to or larger than the rod gland diameter to give interference on the
O-ring's outside diameter (O.D.). The O-ring's outside diameter (O.D.) should not exceed 3% of the rod gland diameter for O-rings
with an inside diameter (I.D.) greater than 250 mm, or 5% for O-rings with an inside diameter (I.D.) smaller than 250 mm. For
O-rings with an inside diameter (I.D.) smaller than 20 mm, this is not always possible due to tolerance issues, which can result in a
greater O-ring outside diameter (O.D.) interference.

Compression
The difference between the original O-ring cross-section and the final O-ring cross-section once installed is known as the
compression squeeze.
Compression Squeeze
C/S
Compression Squeeze = C/S - D
D
This can usually be expressed as a percentage:
O-ring C/S Squeeze (%) = Compression Squeeze x 100

Gland Fill
The gland fill is the percentage of the gland that is occupied by the O-ring. It is calculated by dividing the cross-sectional area
(CSA) of the O-ring by the cross-sectional area of the gland.
Area of a circle = πr2 and r = d , where d = diameter (C/S)
2
( )
Therefore, O-ring CSA = π C/S 2

Gland CSA = D x w*

w- groove width, D- groove depth
x 100
* Effect of gland angle and extrusion gap not
addressed.
It is important to consider the groove fill or occupancy of the installed O-ring to avoid detrimental effects on radial sealing
performance. Groove fill of the installed O-ring should not be more than 85 % to allow for possible O-ring thermal expansion,
volume swell due to fluid exposure and effects of tolerances.
Volume change is the increase or decrease of the volume of an elastomer after it has been in contact with a fluid, measured in
percent (%). For static O-ring applications volume swell up to 30 % can usually be tolerated. For dynamic applications, 10 or 15
% swell is a reasonable maximum unless special provisions are made in the gland design itself. This is a general rule and there may
occasionally be exceptions.
It is also important to note there are significant differences in the coefficients of thermal expansion between the O-ring material and
the groove materials. Elastomers can have coefficients of thermal expansion 7 to 20 times higher than that of metal, such as steel.

O-Ring Design Guide
Extrusion Gap
Extrusion is a concern for radial seals where there is gap between the piston and the bore for a piston type seal or between the rod
and the bore for a rod type seal. It is not typically a concern for face type seals where the metal parts to be sealed are in contact
line-to-line. The issue is that at higher pressures and especially for softer O-ring elastomers, the O-ring can be forced by the pressure
into the small gap between the piston (or rod) and the bore. Unless the bore and the piston (or rod) are ensured to remain
concentric by the hardware, we have to assume that entire possible gap can shift to one side (see diagram below).

Fluid Pressure (psi)
There are different methods to counter O-ring extrusion. One
of these methods is to simply increase the durometer rating of
the O-ring. However, as you increase the durometer, the O-ring
can become less malleable. Another option would be the use of
anti-extrusion devices. These are thin rings made of hard plastic
materials such as PTFE, Nylon, and PEEK or a harder durometer
rubber such as Nitrile or Polyurethane. Once in place these rings
will provide essentially zero clearance.

O-Ring Design Guide
Extrusion (and/or Nibbling)
Description: The seal develops ragged edges (generally on the low-pressure
side) which appear tattered.
Contributing Factors: Excessive clearances. Excessive pressure. Lowmodulus/hardness elastomer. Excessive gland fill. Irregular clearance gaps.
Sharp gland edges. Improper sizing.
Suggested Solutions: Decrease clearances. Higher-modulus/hardness
elastomer. Proper gland design. Use of polymer backup rings.
Over-Compression
Description: The seal exhibits parallel flat surfaces (corresponding to the
contact areas) and may develop circumferential splits within the flattened
surfaces.
Contributing Factors: Improper design-failure to account for thermal or
chemical volume changes, or excessive compression.
Suggested solutions: Gland design should take into account material
responses to chemical and thermal environments.
Spiral Failure
Description: The seal exhibits cuts or marks which spiral around its
circumference.
Contributing Factors: Difficult or tight installation (static). Slow
reciprocating speed. Low-modulus/hardness elastomer. Irregular O-ring
surface finish (including excessive parting line). Excessive gland width.
Irregular or rough gland surface finish. Inadequate lubrication.
Suggested Solutions: Correct installation procedures. Higher-modulus
elastomers. Internally lubed elastomers. Proper gland design. Gland surface
finish of 8-16 microinch RMS. Possible use of polymer backup rings.

O-Ring Design Guide
Compression Set
Description: The seal exhibits a flat-sided cross-section, the flat side
corresponding to the mating seal surfaces.
Contributing Factors: Excessive compression. Excessive temperature.
Incompletely cured elastomer. Elastomer with high compression set.
Excessive volume swell in chemical.
Suggested Solutions: Low compression set elastomer. Proper gland design
for the specific elastomer. Confirm material compatibility.
Outgassing/Extraction
Description: The failure is often very difficult to detect from examination of
the seal. The seal may exhibit a decrease in cross-sectional size.
Contributing Factors: Improper or improperly cured elastomer. High
vacuum levels. Low hardness/plasticized elastomer.
Suggested Solutions: Avoid plasticized elastomers. Ensure all seals are
properly post-cured to minimize outgassing.
Installation Damage
Description: The seal or parts of the seal may exhibit small cuts, nicks or
gashes.
Contributing Factors: Sharp edges on the glands or components. Improper
sizing of elastomer. Low-modulus/hardness elastomer. Elastomer surface
contamination.
Suggested Solutions: Remove all sharp edges. Proper gland design. Proper
elastomer sizing. Higher-modulus/hardness elastomer.

O-Ring Design Guide
Chemical Degradation
Description: The seal may exhibit many signs of degradation including
blisters, cracking, voids or discoloration. In some cases, the degradation is
observable only by measurement of physical properties.
Contributing Factors: Incompatibility with the chemical and/or thermal
environment
Suggested Solutions: Selection of more chemically resistant elastomer.
Thermal Degradation
Description: The seal may exhibit radial cracks located on the highest
temperature surfaces. In addition, certain elastomers may exhibit signs of
softening-a shiny surface as a result of excessive temperatures.
Contributing Factors: Elastomer thermal properties. Excessive temperature
excursions or cycling.
Suggested Solutions: Selection of an elastomer with improved thermal
stability. Evaluation of the possibility of cooling sealing surfaces.
Explosive Decompression
Description: The seal exhibits blisters, pits or ruptures on its surface.
Absorption of gas at high pressure and the subsequent rapid decrease in
pressure. The absorbed gas blisters and ruptures the elastomer surface as the
pressure is rapidly removed.
Contributing Factors: Rapid pressure changes. Low-modulus hardness
elastomer.
Suggested Solutions: Higher-modulus/hardness elastomer. Slower
decompression (release of pressure).

O-Ring Design Guide
Plasma Degradation
Description: The seal often exhibits discolouration, as well as powdered
residue on the surface and possible erosion of elastomer in the exposed area.
Contributing Factors: Chemical reactivity of the plasma. Ion
bombardment (sputtering). Electron bombardment (heating). Improper
gland design. Incompatible seal material.
Suggested Solutions: Plasma-compatible elastomer and compound.
Minimize exposed area. Examine gland design.
Contamination
Description: The seal exhibits foreign materials on the surface and/or within
the O-ring.
Contributing Factors: Process environment deposition. Reactions or
degradation of the elastomer. Non-semiconductor-grade elastomer.
Suggested Solutions: Specify contamination level including manufacturing
and packaging of the seals.
Abrasion
Description: The seal or parts of the seal exhibit a flat surface parallel to the
direction or motion. Loose particles and scrapes may be found on the seal
surface.
Contributing Factors: Rough sealing surfaces. Excessive temperature.
Process environment containing abrasive particles. Dynamic motion. Poor
elastomer surface finish.
Suggested Solutions: Use recommended gland surface finishes. Consider
internally lubed elastomers. Eliminate abrasive components.
