Description

When your hydraulic system starts acting up—whether it’s a sluggish three-point hitch, jerky loader operation, or puddles under your tractor—worn seals are usually the culprit. This HM21 hydraulic seal gives you a reliable replacement that stops leaks and gets your hydraulics back to full performance without breaking the bank.

What You’re Getting

Type HM21 designation ensures proper fit for specific hydraulic applications
0.25-inch width designed for precise sealing in narrow groove applications
High-quality seal material that resists hydraulic fluid and temperature extremes
Direct replacement design fits original equipment specifications

Built for Real Farm Work

This seal works in hydraulic cylinders, pumps, and valve assemblies across a wide range of agricultural equipment. Whether you’re dealing with loader cylinders, three-point lift systems, or remote hydraulic circuits, the HM21 type specification ensures you’re getting the right seal for applications where space is tight and sealing is critical.

Made to Last

Farm hydraulics take a beating from pressure spikes, contamination, and constant cycling. This seal is built with compounds that stay flexible through temperature swings and resist breakdown from modern hydraulic fluids, so it keeps doing its job season after season.

Good to Know

The 0.25-inch width makes this a specialized seal for specific groove dimensions—make sure you’ve got the right measurements before installation. Keep the seal groove and mating surfaces clean during installation, and use a little hydraulic fluid to lubricate the seal as you work it into place. Avoid using picks or sharp tools that might damage the sealing lip.
