Push-Fit Brass Fitting

This Legris push-fit fitting joins 5/16 inch OD tubing to a 3/8 inch male NPT thread. The brass body uses C36000 grade material and includes pre-applied thread sealant. Rated for 290 psi maximum pressure and 175 degrees F maximum temperature. Supplied in a pack of 10 pieces.

Suits vacuum lines and push-fit systems

Installers needing a quick-connect transition from tubing to female-threaded ports will find this fitting convenient. Builders requiring compression, flare or welded joints should select a different connection style. The pack quantity may exceed needs for single repairs.

5/16 inch tube to 3/8 NPT thread

The critical specification is the combination of 5/16 inch outer diameter push-to-connect on one end and 3/8 inch male NPT on the other. Verify both dimensions against your tubing and port before ordering.

Questions about this item

What tube size must I already have to connect to the 5/16 inch push-fit end?

You need tubing with a 5/16 inch outer diameter for the push-to-connect side to seal properly.

Will the 3/8 inch NPT male threads mate with my existing 3/8 inch female NPT ports?

Yes, the 3/8 inch MNPT side threads directly into standard 3/8 inch female NPT ports.

How can I confirm the fitting is holding pressure after installation?

Pressurise the system up to 290 psi and check for leaks; the pre-applied sealant and push-fit grip should maintain a tight seal.
