Description

When hydraulic fluid starts finding its way where it shouldn’t be, you know it’s time for new seals. This HM21 type hydraulic seal keeps your equipment’s fluid systems working like they’re supposed to—containing pressure where you need it and keeping contamination out. Whether it’s a leaky cylinder, pump housing, or valve assembly, having the right seal on hand means getting back to work instead of waiting on parts.

Key Features

HM21 specification ensures compatibility with common hydraulic applications across multiple equipment brands
Quarter-inch width provides solid sealing surface for reliable long-term performance
Quality construction handles the pressure spikes and temperature swings that come with farm work
Universal design fits various hydraulic components where this seal specification is required

Built for Real Farm Work

This seal works in hydraulic systems found throughout agricultural equipment—tractors, balers, combines, loaders, and implements. Farm hydraulics take a beating with constant pressure changes, contaminated fluid, and temperature extremes from working in all weather conditions. This HM21 seal is built to handle those challenges while maintaining the tight tolerances hydraulic systems need to function properly.

Made to Last

Agricultural hydraulic seals need to withstand conditions that would destroy automotive or industrial seals. This one’s designed for the dirt, vibration, and extended service intervals common in farm equipment. The materials resist breakdown from modern hydraulic fluids while maintaining flexibility through countless pressure cycles.

Good to Know

Before installing any hydraulic seal, clean the bore thoroughly and check for scratches or wear that could damage the new seal. A light coating of clean hydraulic fluid helps during installation and prevents seal damage. Keep a few of these on hand—hydraulic leaks always seem to happen at the worst possible time.
