Press Adapter for Thermostatic Mixing Valve

This Legend Valve 115-333NLP press adapter connects directly to a thermostatic mixing valve in a potable water system. It is designed for professional plumbing installations where a secure press connection is required. The component is supplied new and carries the manufacturer part number 115-333NLP for identification.

Suitable for Press-Fit Copper Systems Without

This adapter suits installers working with press-fit copper piping who need a straight connection to a TMV body without an integrated check valve. It is not for systems that require a built-in backflow prevention device at this connection point. Buyers needing an integrated check valve should select a different fitting configuration.

1/2 Inch Nominal Size with No Check Valve

The single specification that determines compatibility is the 1/2 inch nominal size combined with the absence of a check valve mechanism. This defines the pipe diameter it accepts and confirms it cannot prevent reverse flow on its own. Verify the TMV inlet matches this size and that system design handles backflow separately.

Questions about this item

How do you install the 1/2" press adapter without a check valve, and which step causes leaks?

Press the 1/2" adapter onto the pipe using a calibrated press tool; the step that causes leaks is skipping the full insertion depth before pressing.

What maintenance will the 1/2 NL TMV press adapter need over time?

Inspect the press joint and O-ring seals annually for corrosion or mineral buildup; replace the adapter if the connection shows seepage or the press ring is deformed.

What limit appears first on the 1/2" press adapter under sustained hot-water use?

The press-seal temperature rating is reached before the pipe itself fails; prolonged exposure above rated temperature degrades the O-ring and can loosen the joint.
