Description

When you notice fuel weeping around connections or smell diesel while you’re working, don’t overlook the small O-rings in your fuel system—these tiny seals handle extreme pressures and when they fail, your engine performance goes downhill fast. This replacement O-ring restores proper sealing in your fuel tube connections, preventing leaks that waste fuel and let contaminants into your system.

Key Features

Precision-molded to handle high fuel pressure without deforming or cracking
Chemical-resistant material that won’t deteriorate from contact with diesel fuel
Exact fit replacement that restores factory-tight sealing
Temperature-stable compound that performs in both summer heat and winter cold

Built for Real Farm Work

These O-rings serve the fuel systems on New Holland T5 utility tractors, T6 series mixed farming machines (95 to 180 horsepower), and T7 series tractors (150 to 340 horsepower) that work intensive agricultural operations. Whether you’re running a loader, pulling planters, or powering through harvest season, these tractors demand reliable fuel delivery to keep you productive.

Made to Last

This isn’t a generic seal from an industrial supplier—the compound is specifically formulated to resist the additives in modern diesel fuel that can cause standard O-rings to swell and fail. It’s engineered to maintain its sealing properties through thousands of hours of operation in agricultural conditions.

Good to Know

Keep everything clean during installation—any contamination can damage sensitive injection components, so work in a clean environment and have rags ready to catch fuel spillage. Replace the O-ring any time you disconnect fuel lines for service, as reusing old seals often leads to leaks down the road.
