Description
When you’re fixing a hydraulic leak or maintaining your tractor’s engine, nothing’s more frustrating than having to stop work because you don’t have the right O-ring. This compact 3/8 inch inside diameter seal fits those common small connections where seepage turns into puddles if you don’t catch it early. Whether it’s a hydraulic fitting, fuel system connection, or coolant joint, this little rubber ring does the big job of keeping fluids where they belong.
What You’re Getting
- Perfect size for smaller hydraulic fittings and engine connections that need reliable sealing
- Made of 70 Durometer Buna-N rubber that handles heat, pressure, and chemical exposure
- Comes in a 10-pack so you’ll have spares when you need them most
- Standard 1/16 inch width provides proper seal compression without over-squeezing
Built for Real Farm Work
These O-rings work across plumbing, hydraulics, heavy equipment, automotive, and irrigation applications—basically anywhere you need a small but dependable seal. From compact utility tractors to larger row-crop machines, these rings seal the connections that keep hydraulic cylinders, fuel systems, and cooling systems working properly. O-rings appear everywhere on modern equipment – hydraulic fittings, fuel system connections, oil filter housings, coolant joints, and air system fittings all depend on these simple but crucial seals.
Made to Last
Despite their simplicity, O-rings face harsh conditions. Heat cycles cause them to harden and lose elasticity. Chemical exposure from fuels and fluids degrades rubber compounds. That’s why this Buna-N compound is specifically chosen to resist the oils, fuels, and hydraulic fluids it’ll encounter on your equipment.
Good to Know
Keep these O-rings in a cool, dry place away from direct sunlight—heat and UV light age rubber faster than normal use. One failed O-ring can drain hydraulic systems, create fuel leaks, or allow air into critical systems, so having extras on hand saves time and prevents bigger problems down the road.
