1/8 in OD Brass Push-Fit Adapter

This Legris 3175 53 14 male connector joins 1/8 in outer-diameter tubing to a 1/4 in male NPT thread. The push-to-connect design suits vacuum and fluid-transfer applications where quick assembly matters. Brass C36000 construction with pre-applied thread sealant gives a reliable seal at up to 290 psi. Supplied as a pack of 10 fittings.

290 psi and 175 °F operating limits

The brass body and C36000 material grade handle continuous pressure to 290 psi and temperatures to 175 degrees F without degradation. Pre-applied sealant removes the need for tape or paste, reducing leak paths during thermal cycling. No moving parts means silent operation and zero power draw in any installed orientation.

Pre-applied thread sealant included

Each fitting arrives with sealant already on the male NPT threads, cutting installation time and eliminating separate tape purchases. The push-to-connect tube end grips 1/8 in OD tubing without tools or clamps. Pack of 10 provides spares for multi-point vacuum manifolds or future maintenance.

Questions about this item

How do I install the 1/8 in OD push-to-connect side, and what step is often missed?

Push the tube firmly into the fitting until it seats against the internal stop; the common mistake is not pushing deep enough to engage the collet.

What maintenance or replacement will the pre-applied thread sealant need later?

The sealant is single-use; if the 1/4 in MNPT connection is broken and remade, fresh thread sealant must be applied.

Which limit appears first during sustained use at the 290 psi rating?

The 175 °F maximum operating temperature is typically reached before the pressure limit under continuous flow conditions.
