Description
When you’re dealing with hydraulic leaks or planning a preventive rebuild, having the right O-rings on hand makes all the difference. A failed seal can shut down your operation fast, whether you’re in the middle of planting season or trying to get hay in before weather hits. This Weatherhead Buna-N O-ring seals hydraulic connections tight and keeps your equipment running when you need it most.
What You’re Getting
- Temperature range from -40°F to +250°F handles extreme weather and heat buildup
- Buna-N compound resists hydraulic fluid, fuel, and oils that break down cheaper seals
- 3/8-inch size fits common hydraulic fittings on tractors and implements
- Precision manufacturing ensures proper compression and leak-free operation
Built for Real Farm Work
This O-ring works in hydraulic systems across all types of farm equipment—tractors, loaders, balers, combines, and implements that rely on hydraulic power. Whether you’re sealing remote cylinder connections, pump fittings, or valve assemblies, this seal handles the pressure and contamination that comes with field work.
Made to Last
Weatherhead has been making hydraulic components for decades, and their Buna-N compound stands up to the abuse farm equipment dishes out. The material stays flexible in cold weather and won’t crack under heat, maintaining a tight seal through temperature swings and constant pressure cycles.
Good to Know
Keep a few extras in your toolbox—O-rings fail at the worst possible times. Clean the groove thoroughly before installation and check that the fitting threads aren’t damaged. A light coat of hydraulic fluid helps the O-ring seat properly without twisting or pinching.
