Snap-In Hydraulic Wiper Seals

A snap-in hydraulic wiper seal is an elastic scraper fitted at the cylinder head to clean a retracting rod. Its outward lip removes dust, mud and moisture before these contaminants reach the rod seal, while the flexible body locks into a machined housing groove without a metal case.

Questions about snap-in hydraulic wiper seals

What should I send to identify snap-in hydraulic wiper seals?

Send rod diameter, housing groove diameter, groove width, lip arrangement, contamination type. Confirm the retention groove form and whether an inward secondary lip must manage the rod lubrication film. A clear photograph, drawing or readable reference can resolve details that dimensions alone do not show.

How should I select snap-in hydraulic wiper seals?

Choose polyurethane for strong abrasion resistance or a compatible rubber where flexibility, fluid or temperature conditions favour it. Confirm the mating parts and operating environment before ordering, since an apparently similar size can use a different profile, material or internal arrangement.
