Description
When you’re dealing with a hydraulic leak or planning maintenance on your tractor, having the right O-ring size on hand can save you a trip to town and keep you running. This compact 3/8 inch ID O-ring fits a wide variety of smaller hydraulic connections and fittings that show up all over farm equipment. Whether it’s a power steering leak, a loader connection that’s weeping, or a hydraulic filter housing that won’t seal properly, this size shows up more often than you’d expect.
What You’re Getting
- 10-pack means you’ll have spares when you need them most
- 70 durometer Buna-N rubber handles hydraulic fluid, fuel, and temperature swings
- Compact 3/32 inch width fits tight spaces without bulk
- Consistent quality that seals properly without over-compressing
Built for Real Farm Work
These O-rings work across plumbing, hydraulics, heavy equipment, automotive, and irrigation applications, making them handy to have around the shop. You’ll find this size in hydraulic quick-connects, filter housings, valve blocks, and cylinder connections on everything from compact tractors to larger farm equipment. The versatility means one pack covers multiple repair needs.
Made to Last
Buna-N rubber resists the oils and fluids that would destroy regular rubber, while the 70 durometer rating provides the right balance of flexibility and strength. These O-rings maintain their sealing properties through temperature extremes and pressure cycles that come with normal equipment operation.
Good to Know
Always clean the groove thoroughly before installing a new O-ring – old hydraulic fluid residue can cause premature failure. A light coating of compatible hydraulic fluid on the O-ring makes installation easier and provides initial lubrication. Keep the package sealed until you need them to prevent contamination and premature aging.
