Description

When you’re connecting hydraulic components with different thread types, you need an adapter that won’t leak or fail when the pressure builds. This steel hydraulic adapter lets you connect a 3/8 female O-Ring Boss fitting to a 3/8 male pipe thread fitting, making it easy to integrate different hydraulic components on your tractor or equipment.

What You’re Getting

Solid steel construction that handles high-pressure hydraulic systems without cracking
Precision machined threads that create reliable, leak-free connections every time
Compact design that doesn’t add unnecessary bulk to your hydraulic setup
Direct replacement adapter that eliminates the need for custom fabrication

Built for Real Farm Work

This adapter bridges the gap between O-Ring Boss fittings (common on modern hydraulic valves and cylinders) and standard pipe thread fittings found on older equipment and aftermarket components. It’s the kind of fitting you’ll find in hydraulic systems across all types of farm equipment, from loader valves to remote hydraulic outlets.

Made to Last

Steel construction means this adapter can handle the vibration, pressure spikes, and temperature changes that come with farm work. The threads stay sharp and the seal surfaces remain smooth, so you get reliable performance season after season.

Good to Know

Make sure you have the right thread sealant or tape for the pipe thread side—that’s what keeps it from weeping. The O-Ring Boss side uses an O-ring for sealing, so check that it’s in good shape before installation. If you’re working on older equipment, having a few of these adapters in your toolbox saves trips to town when mixing thread types.
