Brass push-fit adapter for vacuum lines

This Legris 3175 62 21 fitting joins 1/2 in tube to a 1/2 in MBSPT port using a push-to-connect end and a threaded end. The brass body uses material grade C36000 and comes with pre-applied thread sealant. Ten pieces are supplied in silver finish for pneumatic or vacuum plumbing work.

Sustained pressure and temperature envelope

The adapter is rated for a maximum operating pressure of 290 psi and a maximum operating temperature of 175 Degrees F. These limits apply to continuous service rather than brief spikes. The brass construction and captive sealant maintain joint integrity across the full range without retightening.

Thread and tube interface constraints

Side B uses a 1/2 in MBSPT taper thread while Side A accepts 1/2 in tube outer diameter in a push-to-connect socket. Overall length is 13/16 in, so the fitting occupies minimal space in tight routings. No separate thread tape or compound is required because sealant is factory-applied to the taper threads.

Questions about this item

Does the brass body and pre-applied sealant handle continuous 290 psi pressure without leaking or overheating at 175 Degrees F?

The fitting is rated for a maximum operating pressure of 290 psi and a maximum operating temperature of 175 Degrees F, with a brass C36000 body and pre-applied thread sealant designed for those limits.

What tube and thread sizes must my existing lines have to connect directly to this 1/2 in push-fit adapter?

Side A accepts 1/2 in outer-diameter tube via push-to-connect; Side B is a 1/2 in MBSPT thread, so your mating port must match that thread form.

Will the 13/16 in overall length and push-to-connect end fit onto the 1/2 in copper tubing I already have in place?

The adapter’s Side A is built for 1/2 in tube outer diameter with a push-to-connect design, and its overall length is 13/16 in, so it will seat on standard 1/2 in copper if the tube is clean and round.
