Brass Push-Fit Adapter with MNPT Thread

This Legris 3175 60 18 adapter connects 3/8 inch tubing to a 3/8 inch male NPT thread using a push-to-connect design. The brass body uses C36000 grade material and includes pre-applied thread sealant. It is supplied as a pack of 10 new fittings for plumbing or pneumatic systems.

Suited for Vacuum and Compressed Air Lines

Installers needing a quick, tool-free joint rated for 290 psi and 175 degrees F will find this fitting matches the spec. It is not for applications requiring a different thread standard, a larger tube diameter, or a higher temperature rating than the listed maximum.

3/8 Inch Push-to-Connect to 3/8 Inch MNPT

The defining specification is the combination of a 3/8 inch push-to-connect port on one side and a 3/8 inch MNPT thread on the other. Verify that both the tube outer diameter and the mating thread match these exact dimensions before purchase.

Questions about this item

Does the pre-applied thread sealant on the 3/8 in MNPT end need replacement after repeated disassembly?

The pre-applied sealant is designed for initial installation; if the fitting is removed and reinstalled, fresh thread sealant should be applied to maintain a leak-free joint at 290 psi.

Will the 290 psi pressure rating or the 175 °F temperature limit be reached first in a continuous vacuum line?

In vacuum service the 290 psi pressure ceiling is never approached, so the 175 °F temperature limit becomes the governing constraint for sustained operation.

How warm does the brass body get when the line runs at the 175 °F maximum all day?

The C36000 brass body will essentially match the 175 °F fluid temperature, so the fitting surface becomes too hot to touch and requires insulation or guarded access.
