Description
When you’re plumbing hydraulic lines or air systems on your equipment, sometimes you need to adapt between different pipe thread sizes or add a swivel connection where space is tight. This steel adapter takes a 1/4″ female pipe thread and steps it up to 3/8″ female pipe thread with a swivel feature that lets you position your connections exactly where they need to be without fighting rigid fittings.
What You’re Getting
- Steps up from 1/4″ NPSM female threads to 3/8″ NPSM female threads in one compact fitting
- Swivel design lets you rotate the connection to avoid tight spots and awkward angles
- Heavy-duty steel construction handles hydraulic pressures and temperature swings
- NPSM threads seal without tape when properly tightened – just like the factory intended
- Compact design fits in cramped spaces where larger fittings won’t work
Built for Real Farm Work
This adapter works great in hydraulic systems, pneumatic setups, and anywhere you need to connect different pipe thread sizes with some flexibility. You’ll find it handy when retrofitting older equipment with newer components, adding gauges or accessories to existing lines, or just making connections that need to bend around obstacles.
Made to Last
Steel construction means this fitting won’t crack under pressure like some cheaper alternatives. The swivel mechanism is built to handle repeated positioning without wearing loose, and the threads are precisely machined for reliable sealing. It’s designed to handle the vibration, temperature changes, and pressure cycles that come with agricultural equipment.
Good to Know
NPSM threads are designed to seal metal-to-metal when properly torqued, so you typically don’t need thread sealant or tape. Just make sure both surfaces are clean and tighten to proper specifications. The swivel feature works best when you leave it slightly loose during installation, position everything where you want it, then snug it down.
