12 mm Straight Union

The Legris 3106 12 00 is a push-fit straight union designed to join two 12 mm outer diameter tubes. It is supplied as a pack of ten new fittings for pneumatic plumbing installations.

Suitable for compressed air lines

This union suits installers who need a tool-free connection between equal 12 mm tubes in air systems rated up to 290 psi and 176 °F. It is not for applications requiring threaded ends, different tube diameters, or fluid media other than air.

Fiberglass-reinforced nylon body

The fitting body uses fiberglass-reinforced nylon with a black finish and contains no pre-applied thread sealant. This material choice determines chemical compatibility and mechanical strength for the stated pressure and temperature limits.

Questions about this item

Does the 290 psi rating or 176 °F limit mean the fitting gets hot or noisy when air runs through it all day?

The union is a passive push-fit fitting with no moving parts, so it produces no noise and generates no heat of its own during continuous airflow.

What tubing must I already have for the 12 mm push-to-connect ends to seal properly?

You need 12 mm outer-diameter tubing compatible with push-to-connect fittings; the union accepts the same size on both sides.

Will this black fiberglass-reinforced nylon union work alongside older metal compression fittings on the same 12 mm line?

Yes, it connects to 12 mm tube just like a metal fitting, but the nylon body and push-to-connect design mean no tools or thread sealant are required for the union itself.
