(Hallite 839) H839 Wiper Seal / Dust Seal
(Hallite 839) H839 Wiper Seal / Dust Seal overview
The Hallite 839 (also known as H839) is a high-performance, double-lipped snap-in wiper seal engineered to protect hydraulic cylinder assemblies. Manufactured from Hallite’s proprietary Hythane® 181 polyurethane, this wiper offers exceptional abrasion resistance, elasticity, and long service life in demanding industrial environments.
Its primary wiper lip scrapes away external dirt, mud, and moisture, while the precision-trimmed secondary sealing lip works in reverse to minimize oil transfer and keep the rod clean.
