Push-Fit Brass Fitting Pack

This Legris 3121 pack supplies ten push-to-connect fittings that join 3/8 in tube to a 1/4 in MNPT thread. The brass bodies suit vacuum and compressed-air lines in workshop and automotive plumbing. Each fitting arrives with pre-applied thread sealant to speed installation. The silver finish identifies the C36000 brass grade at a glance.

Sustained Pressure Performance

Rated for 290 psi maximum operating pressure, the fittings maintain seal integrity during continuous pneumatic or vacuum cycles. The push-to-connect design resists vibration loosening better than compression nuts under repeated pressure swings. Brass construction withstands the 175 Degrees F temperature ceiling without creep deformation. The pre-applied sealant remains effective across the full pressure and temperature envelope.

Thermal and Power Characteristics

Brass conducts heat rapidly, so fitting temperature tracks the fluid temperature up to the 175 Degrees F limit. No electrical power is drawn and no moving parts generate noise during operation. The compact 1 13/32 in overall length minimises pressure drop in tight routing. Sealant lubrication eliminates the need for additional thread compounds that could contaminate the system.

Questions about this item

Does the brass body or the pre-applied sealant degrade when the fitting runs continuously at 290 psi and 175 °F?

The C36000 brass and included thread sealant are rated for the stated 290 psi maximum pressure and 175 °F maximum temperature during continuous operation.

What thread size and tubing must the installer provide for the male NPT and push-to-connect ends?

The fitting accepts a 1/4 in male NPT thread on side B and a 3/8 in outer-diameter tube on the push-to-connect side A.

Will the 1 13/32 in overall length clear adjacent fittings on a legacy 1/4 in NPT manifold?

At 1 13/32 in long the compact brass body fits most existing 1/4 in NPT ports without interfering with neighbouring components.
