Question by: Ronnie T on Jul 22, 2025, 6:19 AM
Reckon this'll keep the grit out of my cylinder?
Answer by: Customer Support on Jul 24, 2025, 6:48 AM
That's exactly what it's designed to do. This wiper seal is made to keep dirt, dust, and moisture from messing with your hydraulic cylinder rods when they retract.
Question by: Ray B on Jan 24, 2026, 3:58 PM
what exactly does a wiper seal do in a hydraulic cylinder, and is that what this part is?
Answer by: Customer Support on Jan 25, 2026, 6:57 PM
Wiper seals sit at the outer end of the rod gland and clean the rod on its way back into the cylinder. Every time the rod retracts, the wiper scrapes off dirt, dust, and moisture before any of that debris can get past the internal seals and into the hydraulic fluid. That's exactly what this Hercules part is built for. It's a standard rod wiper meant for industrial hydraulic cylinder assemblies where keeping contaminants out is the whole job.

got a cylinder rod that keeps dragging grit back in when it retracts. is that what this wiper is for?
Answer by: Customer Support on Mar 20, 2026, 9:53 PM
On the retract stroke, the wiper’s job is to scrape the rod clean and keep dirt, dust, and moisture from getting pulled into the gland area. That helps protect the internal seals and the hydraulic fluid from outside contamination.
