Parker 6306 56 60WP2 Union

The Parker 6306 56 60WP2 Union connects 1/4 in and 3/8 in tubing using push-to-connect ends on both sides. The white bio-based nylon body is rated for vacuum applications and a maximum operating pressure of 230 psi. Each pack contains ten fittings with an overall length of 1 5/8 in.

Suits unequal tube joins

This union suits installers joining 1/4 in tubing to 3/8 in tubing in vacuum lines up to 230 psi and 200 Degrees F. It does not suit systems requiring threaded connections, higher temperature ratings, or identical tube diameters on both ends.

1/4 in x 3/8 in push-to-connect

The defining specification is the mixed tube outer diameter: side A accepts 1/4 in tube and side B accepts 3/8 in tube, both with push-to-connect action. This single mismatch determines whether the fitting matches the plumbing layout.

Questions about this item

What tube diameters does the Parker 6306 56 60WP2 union connect?

This push-fit union joins a 1/4 in tube on one side to a 3/8 in tube on the other, with an overall length of 1 5/8 in.

How do you install the push-to-connect ends, and what is the common mistake?

Push each tube firmly into the fitting until it seats; the step people miss is pulling back to confirm the grip ring has locked the tube in place.

When should the bio-based nylon fitting be replaced?

Replace it if you see cracking, discoloration or leakage, especially after exposure near the 200 °F temperature limit or 230 psi pressure limit.
