Designed with the same look and feel as Hallite’s popular T842 and engineered to fit the same ‘D’ groove
as our T520 wiper, the T820 wiper was developed specifically for harsher environments where the
wiper is subject to numerous contaminants. This is common in agriculture, off-highway and forestry
equipment.
What makes the T820 unique is the protective debris
guard, which entirely covers the retaining groove. This
feature, known as Hallite’s Umbrella Wiper Technology, offers added protection
to the integrity of the hydraulic system. Often with a normal ‘D’ style wiper, it is
possible to trap liquids or debris in the wiper cavity or pocket around the O.D.
of the wiper. This can eventually corrode the pocket or pass debris around the
wiper, contaminating the entire system and resulting in downtime, as well as
repair and warranty costs.
Another advantage of the T820 is the ease of installation. Unlike metal
press-in wipers normally specified for harsh environments, the T820 can be
installed without the use of special tooling.
The T820 also incorporates the performance I.D. ribs found on the T520 to enhance low friction operation, as well as prevent
pressure trap between the wiper and the primary rod seal.
The standard material offering is the same hydrolysis-resistant Hythane® 181 polyurethane as other Hallite high performance
seals. This material has excellent low temperature capabilities and compression set characteristics, along with excellent
wear and abrasive resistance, and proven performance with a variety of fluids. The T820 is also offered in a number of other
polyurethanes such as the Hythane® 361 and Hythane® 371, a very aggressive scraping material with a proven track record in
forestry, mining and aggregate industries.
