Flange Head O-Ring for Hydraulic Connections – Buna-N Rubber

Description

When you’re working with hydraulic fittings and connections on your equipment, you know how frustrating it can be when seals start leaking. Whether it’s a loader, implement hydraulics, or your tractor’s remote outlets, a failed O-ring means lost fluid pressure, contamination getting in, and that messy puddle of hydraulic oil under your machine. This Buna-N flange head O-ring is designed to seal tight and keep your hydraulic systems working the way they should.

What You’re Getting

• Buna-N rubber construction that resists hydraulic fluids and temperature swings
• Precision sizing for proper compression and reliable sealing performance
• Code 61/62 specification meets industry standards for flange connections
• Durable compound that stays flexible through thousands of pressure cycles

Built for Real Farm Work

This O-ring is sized specifically for flange head connections found throughout agricultural hydraulic systems. You’ll find these fittings on three-point hydraulics, loader circuits, implement connections, and remote hydraulic outlets. Whether you’re operating a compact utility tractor or running a big row-crop machine, proper sealing keeps your hydraulic pressure where it needs to be for smooth operation.

Made to Last

Hydraulic O-rings take a beating from pressure cycles, temperature changes, and chemical exposure from hydraulic fluids. This Buna-N compound is formulated to handle these conditions without hardening, cracking, or swelling. The material maintains its sealing properties even when exposed to the heat generated by high-pressure hydraulic systems and temperature extremes from winter shop work to summer field operations.

Installation Notes

Clean the flange surfaces thoroughly before installing the new O-ring, checking for any nicks or scratches that could cause leaks. A light coat of clean hydraulic fluid helps the O-ring seat properly during installation. Don’t over-tighten the connection – proper torque specs ensure the O-ring compresses correctly without being damaged.
