Push-fit brass trap for 12 mm tube

This Legris 3175 fitting joins a 12 mm outer-diameter tube to a 3/8 NPT male thread using a push-to-connect design. The brass body carries a C36000 material grade and ships in a pack of ten. It is intended for vacuum applications where a quick, tool-free seal is required. Pre-applied thread sealant is included on the NPT side.

Pressure and temperature ceiling

The fitting is rated for a maximum operating pressure of 290 psi and a maximum operating temperature of 175 degrees F. These limits define the safe envelope for vacuum or low-pressure fluid lines. Exceeding either value risks leakage or structural failure. No higher pressure or temperature rating is specified for this model.

Brass construction with pre-sealed thread

The C36000 brass body resists corrosion in typical plumbing environments and the silver finish is the natural metal colour. A pre-applied sealant on the 3/8 NPT thread removes the need for tape or paste during installation. The push-to-connect end grabs the 12 mm tube without tools, while the 15/16 in overall length keeps the joint compact. California Proposition 65 warnings apply to chemicals in the product.

Questions about this item

Should I choose the 12 mm OD version or a different tube size?

This fitting is built for 12 mm outer-diameter tube on the push-fit side and 3/8 in NPT male threads on the other; select it only when your line matches both dimensions.

What does the 290 psi rating mean once the fitting is installed?

It is the maximum operating pressure the brass body and C36000 alloy can sustain at up to 175 °F, so the system must never exceed that pressure at temperature.

How does the NPT thread standard affect sealing in practice?

The 3/8 in NPT male thread relies on taper engagement and the pre-applied sealant to create a leak-tight joint without additional tape or compound.
