Brass Union for Threaded Pipework

This brass union joins two 1 1/4 inch female NPT threads in plumbing and hydronic systems. It is rated for a maximum operating pressure of 200 psi and carries a Class 125 designation. The fitting suits installers who need a removable joint for maintenance or equipment replacement. It is not for buyers who require a different thread size or a solder connection.

Straightforward Threaded Assembly

Installation requires only standard pipe thread sealant or tape applied to the male threads entering each end. The union nut tightens by hand and then with a wrench to seat the flat gasket between the halves. The most common issue is cross-threading the nut or damaging the gasket if the joint is forced out of alignment. No special tools beyond pipe wrenches are needed.

Steady Pressure Containment

Under sustained load the brass body and gasket maintain a seal at the rated 200 psi without creep. The material resists the gradual stress relaxation that can affect softer metals over long periods. Thermal cycling in hot water service does not degrade the thread integrity. The fitting is not designed for pressures above the stated maximum or for dynamic shock loads.

Questions about this item

How can I confirm the union is holding pressure correctly after installation?

Pressurise the line up to 200 psi and check for leaks at both 1 1/4 in Female NPT threads; no weeping means the Class 125 brass union is sealing as intended.

What components are included and what must I supply?

The box contains the red brass union only; you must provide pipe sealant or tape and the mating 1 1/4 in Female NPT fittings for each end.

Which pressure class should I select for a 200 psi system?

Choose the Class 125 version listed, as it is rated for 200 psi maximum operating pressure and matches the required 1 1/4 in Female NPT connections.
