Push-Fit Brass Adapter Pack

The Legris 3175 56 13 male connector joins 1/4 inch tube to 1/4 inch MBSPT pipe using a push-to-connect design. Supplied in a pack of 10, these fittings suit vacuum applications in automotive and industrial plumbing systems. The C36000 brass body includes pre-applied thread sealant for faster assembly.

Sustained Pressure and Temperature Rating

Each fitting is rated for a maximum operating pressure of 290 psi and a maximum operating temperature of 175 degrees Fahrenheit. The brass construction and pre-applied sealant maintain sealing integrity under continuous vacuum or pressure cycles. These limits define the safe operating envelope for prolonged service.

C36000 Brass with Pre-Applied Sealant

The material grade C36000 brass and factory-applied thread sealant are the specifications that determine compatibility with the target fluid and installation method. Buyers needing a different thread standard, tube diameter or a fitting without sealant must select another part number.

Questions about this item

Does the 290 psi brass fitting run hot or vibrate when the vacuum system runs continuously?

The brass C36000 body with pre-applied sealant is rated for 175 °F maximum operating temperature and has no moving parts, so it adds no heat or vibration during all-day vacuum use.

What tube and thread sizes must my existing lines have to accept this 3175 56 13 connector?

Your tube must be 1/4 in outer diameter for the push-to-connect side, and the mating port must accept a 1/4 in MBSPT male thread on the other side.

Will these silver-coloured fittings thread into the black HAWA drain components already on my bench?

The connector’s 1/4 in MBSPT male thread mates with any standard 1/4 in BSPT female port, regardless of the component’s material or colour.
