Unequal union for 4 mm and 6 mm tube
The Legris 3106 fitting joins a 4 mm tube to a 6 mm tube using push-to-connect ends on both sides. It is made from black fiberglass-reinforced nylon and rated for 290 psi at up to 176 Degrees F. Each pack contains ten pieces for multiple connection points.
Suited for mixed-size pneumatic circuits
This union suits installers who need a straight link between different tube diameters in compressed-air lines. It is not for systems that exceed the stated pressure or temperature limits, nor for applications requiring threaded connections or integrated sealing compound.
4 mm to 6 mm push-to-connect step
The defining specification is the unequal tube outer diameters of 4 mm and 6 mm on a single push-fit body. This determines whether the fitting matches the two tube sizes in the circuit.

Questions about this item
What tube sizes does the Legris 3106 unequal union connect?
The fitting joins a 4 mm outer-diameter tube on one side and a 6 mm outer-diameter tube on the other, using push-to-connect ports on both ends.
How do you install the push-fit union, and what mistake should be avoided?
Push each tube firmly into its port until it seats; the common error is not inserting the tube far enough past the internal collet, which leaves an unsealed joint.
When should the fitting be replaced in a pneumatic circuit?
Replace it if the collet no longer grips the tube, if the body shows cracks or heat deformation above 176 °F, or if pressure tests exceed the 290 psi rating.
