Push-Fit Y Fitting for Air and Fluids

This Legris 3148 push-fit wye fitting connects a 3/8 inch male NPT thread to two 3/8 inch push-to-connect ports. It handles air, cutting fluids and inert gases at up to 290 PSI. The black fiberglass-reinforced nylon body includes pre-applied thread sealant on the male end. Supplied in a pack of 10 pieces.

Simple Push-to-Connect Installation

No tools are required for the tube connections; push the 3/8 inch OD tubing into ports B and C until it seats. The male NPT thread on port A seals with the supplied sealant — do not add tape or paste. The most common error is insufficient insertion depth, which causes leaks or tube blow-off under pressure.

Verify Thread and Tube Compatibility

Confirm the mating port accepts a 3/8 inch male NPT thread and that your tubing has a 3/8 inch outer diameter. Check that the system pressure stays within the 290 PSI rating and that the media is compatible with fiberglass-reinforced nylon. This fitting is not intended for potable water or high-temperature hydraulic oil.

Questions about this item

How do I confirm the push-fit connections are sealed after installing the 3148 60 18 wye fitting?

Press the 3/8 in tubes firmly into sides B and C until they bottom out; the internal collet grips and the O-ring seals without tools, so a tug test and a visual check that the tube sits flush confirm a sound joint.

What comes in the pack and what extra items are needed to connect the 3/8 in MNPT thread?

The PK10 box contains ten black fiberglass-reinforced nylon wye fittings with pre-applied thread sealant on the 3/8 in MNPT end; you only need 3/8 in OD tubing for the push-to-connect ports.

Which version suits a 290 PSI air or cutting-fluid line with 3/8 in tubing?

The 3148 60 18 model is rated 290 PSI, has 3/8 in MNPT on side A and 3/8 in push-to-connect on sides B and C, making it the correct choice for that pressure and tube size.
