What this fitting does

The Legris 3106 55 00 is a push-fit union designed to join two lengths of 3/16 in tubing in air lines. It uses fiberglass-reinforced nylon rated for 290 psi and 176 Degrees F, and comes in a pack of 10 black pieces for workshop or fleet maintenance.

Check your tubing and pressure

Verify that both tube ends measure 3/16 in outer diameter and are cut square so the push-to-connect grips seal correctly. Confirm the system pressure never exceeds 290 psi and the media temperature stays at or below 176 Degrees F before installing these unions.

Behaviour under continuous load

The fitting holds its rated 290 psi continuously at temperatures up to 176 Degrees F without creep or seal degradation. Fiberglass-reinforced nylon resists vibration fatigue in pneumatic circuits, so the connection remains tight during extended compressor cycles rather than loosening after a short burst.

Questions about this item

What is included in the PK10 pack and do I need any extra parts to install it?

The pack contains ten push-fit union fittings made of black fiberglass-reinforced nylon. No thread sealant is pre-applied, so you must supply your own if the installation calls for it.

How do I decide between the 3/16 in size and any other diameters Legris offers?

This model 3106 55 00 is built specifically for 3/16 in outer-diameter tubing on both ends. Choose it only when your air lines match that exact size; other diameters require a different part number.

What does the 290 psi rating mean when the fitting is in a live compressed-air system?

It is the maximum operating pressure the union can safely hold at up to 176 °F. Do not exceed 290 psi in service or the fitting may fail.
