Push-Fit Brass Adapter

The Legris 3101 is a push-fit adapter fitting designed to join 12 mm tubing to a 3/8 inch MBSPP thread. Brass construction and a 290 psi pressure rating suit pneumatic and vacuum lines in industrial maintenance. Supplied as a pack of ten for repeated installations.

Installers needing 12 mm to 3/8 BSPP

Technicians connecting metric tube to parallel BSPP ports will find the correct thread form and sealant-free push connection. Not suited for installers who need a different tube diameter, a tapered thread form, or a fitting rated above 175 °F.

290 psi maximum operating pressure

The fitting handles up to 290 psi at temperatures up to 175 °F, making it appropriate for standard shop-air and vacuum circuits. Systems running higher pressures or temperatures require a different component.

Questions about this item

How can I verify the push-fit adapter is sealing correctly after installation?

Pressurise the line up to 290 psi and check for leaks at the 12 mm push-to-connect end and the 3/8 in MBSPP thread; the fitting is rated for 175 °F maximum operating temperature.

What comes in the 10-pack and what extra items are needed for a complete connection?

The pack contains ten brass push-fit adapters with 12 mm tube OD and 3/8 in MBSPP threads; thread sealant is not pre-applied, so you must supply compatible sealant or tape separately.

Which version of the 3101 series should I choose for a 12 mm tube and 3/8 in port?

Select model 3101 12 17 — it matches a 12 mm tube outer diameter to a 3/8 in MBSPP thread, with an overall length of 27 mm.
