NPTF Male to NPSM Female Swivel Adapter for Hydraulic Applications

Description

When you’re dealing with hydraulic lines that need to connect different thread types or require movement during operation, this adapter solves the problem. This adapter is designed for tractors and equipment that run hydraulic implements like loaders, backhoes, mowers, and remote cylinders. When you’ve got hydraulic lines that don’t quite match up or need to adapt between different fitting types, this piece bridges the gap and keeps your hydraulics flowing smoothly. The swivel design lets hydraulic lines move naturally without binding or creating stress points.

What You’re Getting

• Heavy-duty steel construction with 1-7/8″ hex design for easy installation
• Swivel female end allows hydraulic lines to rotate freely during operation
• Rated for 1600 PSI operating pressure to handle demanding hydraulic applications
• 1-1/4″ x 11-1/2 thread size on both ends for secure, leak-free connections
• Precision-machined threads ensure proper fit and long service life

Built for Real Farm Work

This valve controls your tractor’s rear remote hydraulics, which power everything from front-end loaders and backhoes to finish mowers, post hole diggers, log splitters, and hydraulic tillers. The NPTF male thread seals metal-to-metal for reliable pressure connections, while the NPSM female swivel uses O-rings for smooth rotation under pressure. This combination is perfect for hydraulic lines that need to move with loader arms, three-point implements, or any hydraulic attachment that shifts during operation.

Made to Last

Weatherhead has been making hydraulic fittings for decades, and this adapter shows why they’re trusted by farmers and mechanics worldwide. The precision-machined threads and quality materials handle the pressure spikes and constant vibration that come with farm equipment operation. The AgSmart brand backing means this adapter is built to handle temperature swings, dirt, and the daily abuse of farm hydraulics.

Good to Know

Always use proper thread sealant on hydraulic fittings – never just tape that can contaminate your system. Clean both fitting surfaces before connecting, and don’t over-tighten as this can damage the threads or crack the fitting body. The swivel end should rotate freely when properly installed – if it binds, back off slightly and check your thread engagement.
