4-inch press male adapter

This Legend Valve adapter connects a 4-inch press fitting to a male NPT thread. It is intended for plumbers and contractors assembling water or hydronic piping systems. The component is supplied new and ready for installation.

California Proposition 65 notice

The product carries a Proposition 65 warning for chemicals known to the State of California to cause cancer and reproductive harm. This disclosure does not change the mechanical function of the adapter but informs safe handling practices on the job site.

Press-to-thread transition limits

A press-to-thread joint relies on the press tool forming a permanent seal on one side while the threaded side remains removable. The connection cannot be rotated after pressing, so pipe alignment must be set before the press operation. Systems requiring frequent disassembly on both ends are not suited to this fitting type.

Questions about this item

Will the 450-761P press connection need re-pressing or seal replacement over time?

The 450-761P press male adapter uses a permanent press connection that does not require re-pressing; the seal is designed for the life of the fitting.

What pressure or temperature limit will the 4-inch adapter reach first during continuous operation?

The adapter is rated for standard plumbing pressures and temperatures; the system design typically reaches its pressure limit before the fitting does.

Does the 450-761P generate noticeable heat or noise when water runs through it all day?

The brass body transmits fluid temperature but produces no mechanical noise and adds negligible heat beyond the water temperature itself.
