3/4-Inch Thermostatic Mixing Valve Adapter

The Legend Valve 115-334NLP is a lead-free thermostatic mixing valve adapter designed for residential and light-commercial bathware installations. It connects to 3/4-inch piping and blends hot and cold water to a safer outlet temperature without an integrated check valve. The transparent body allows visual inspection of internal components during commissioning.

Sustained Temperature Control Under Continuous Flow

Under prolonged draw the valve maintains a stable mixed temperature by dynamically balancing inlet pressures, reducing scald risk during extended showers or fixture use. The press-to-connect design preserves seal integrity over repeated thermal cycles, and the absence of a check valve eliminates a common restriction that can degrade flow during high-demand periods.

Press-Fit Installation Without Thread Sealant

The adapter installs with a standard press tool on compatible copper or stainless tubing, removing the need for solder, tape or thread sealant. Common issues include inserting the tube shy of the full depth mark, which creates a leak path, and applying the tool to misaligned jaws, which can deform the stainless-steel sleeve. A visual check of the transparent housing confirms full insertion before pressurising.

Questions about this item

Will the 115-334NLP valve generate noticeable heat or noise when supplying hot water continuously throughout the day?

The valve body is a passive brass fitting with no moving parts that produce sound or heat; it simply directs pressurised water and remains at the temperature of the supply line.

What pipe size and press-tool profile must I already have to install this 3/4" press adapter?

You need 3/4" copper or stainless tube and a compatible press tool with the correct jaw profile for the manufacturer's press system.

Can the 115-334NLP press adapter connect directly to older threaded fittings I plan to keep?

No, the adapter ends are press-only; joining to threaded components requires a separate press-to-thread transition fitting.
