Frequently Asked Questions

What is a WEATHERHEAD compression fitting adapter used for?

The WEATHERHEAD compression fitting adapter (MPN 7255X20X20) connects 1 1/4 in OD tubing to a 1 1/4 in FNPT port in hydraulic and pneumatic systems. Its flareless bite-type design creates a leak-proof seal without flaring the tube, ideal for high-pressure fluid power applications across industrial machinery.

What are the specifications of the WEATHERHEAD 7255X20X20?

This WEATHERHEAD Ermeto Flareless adapter is a steel compression x FNPT fitting with 1 1/4 in OD tube size and 1 1/4 in pipe size. The flareless bite-type design grips tubing securely without flaring, suitable for steel or stainless steel tube in hydraulic circuits up to system-rated pressures.

Where to buy WEATHERHEAD compression fittings in worldwide?

How to install a flareless bite-type compression fitting?

Installation requires cutting tubing square, deburring, and inserting it fully into the WEATHERHEAD Ermeto Flareless adapter. Tighten the nut until the bite ring grips the tube; over-tightening can damage the seal. Always follow manufacturer torque specifications and use proper tube support for vibration-prone lines.
