Push-Fit Adapter Fitting 12 mm 1/4 in Brass Pack

This pack contains ten Legris 3175 push-fit adapter fittings. Each fitting connects a 12 mm outer-diameter tube to a 1/4 inch MBSPT thread. The brass body uses C36000 material and comes with pre-applied thread sealant. The silver finish identifies the component in the system.

Suited to vacuum lines needing a straight 12 mm

Installers working on vacuum applications with 12 mm tubing and 1/4 inch MBSPT ports will find this pack convenient. The push-to-connect end speeds assembly without tools. Buyers needing a different tube size, a different thread standard or a fitting rated above 290 psi should look at other parts.

Maximum operating pressure 290 psi at 175 °F

The pressure and temperature ratings are the primary limits that decide whether this adapter fits the application. Systems that exceed 290 psi or 175 degrees Fahrenheit require a higher-rated component. The brass construction and pre-applied sealant support the stated range.

Questions about this item

Will the brass body and 290 psi rating hold up when the line runs hot all day?

The fitting is rated for 290 psi and 175 Degrees F, so it handles continuous heat and pressure within those limits.

Do I need 12 mm tubing and a 1/4 in MBSPT port to use these adapters?

Yes — Side A accepts 12 mm tube outer diameter and Side B threads into a 1/4 in MBSPT port.

Can I thread these into older brass ports that already have sealant residue?

Each adapter comes with pre-applied thread sealant, so it seals cleanly into existing 1/4 in MBSPT threads without extra tape.
