Frequently Asked Questions

What is a Weatherhead push-fit adapter fitting used for?

This Weatherhead push-fit adapter fitting connects 1/4 in OD tubing to a 1/4 in NPTF female port in pneumatic or air brake systems. It provides a quick, leak-resistant seal without tools, ideal for industrial air lines, brake systems, and instrumentation where reliable push-to-connect convenience is needed.

What are the specifications of the Weatherhead 1868X4X4 fitting?

The Weatherhead 1868X4X4 is a brass push-fit adapter with a push-to-connect x NPTF configuration. It fits 1/4 in OD tubing on one end and 1/4 in pipe thread on the other. The brass construction resists corrosion, making it suitable for air brake and pneumatic applications up to moderate pressures.

Where to buy Weatherhead push-fit adapter fittings worldwide?

How to install a Weatherhead push-to-connect fitting?

To install a Weatherhead push-fit adapter, cut tubing square, deburr the end, and push it fully into the fitting until it stops. For the NPTF end, apply thread sealant and tighten to the port. No tools are needed for the push side. Always verify the tubing is seated and the connection is leak-free before pressurizing.
