Parker 6306 Push-Fit Adapter Union
This Parker 6306 adapter union connects 5/16 inch and 3/8 inch tubing using push-to-connect ends on both sides. The white bio-based nylon fitting is rated for 230 psi maximum operating pressure and 200 degrees F maximum operating temperature. It comes in a pack of ten pieces for plumbing or vacuum applications.
5/16 in to 3/8 in Push-to-Connect Transition
The single specification that decides fit is the tube outer diameter combination: side A accepts 5/16 inch tubing while side B accepts 3/8 inch tubing. Both ends use push-to-connect style connections with no pre-applied thread sealant included. The overall length measures 1 21/32 inches installed.
Suits Installers Joining Different Tube Sizes
This union suits installers who need a straight transition between 5/16 inch and 3/8 inch lines in vacuum or fluid systems rated within 230 psi and 200 degrees F. Buyers who require threaded connections, larger diameters, or a different material should look at something else.

Questions about this item
How does the 230 psi maximum operating pressure translate to everyday vacuum-line use?
The 230 psi rating means the union will hold well above typical residential vacuum pressures, so normal suction loads will not stress the fitting.
What does the push-to-connect interface on both ends mean for tube compatibility?
Both ends accept tubing by simply pushing it in — one side takes 5/16 in outside-diameter tube, the other takes 3/8 in outside-diameter tube.
What clearance does the 1 21/32 in overall length require inside a cabinet?
The union itself is 1 21/32 in long, so allow at least that much straight run plus room for the tubing to enter each push-fit port without sharp bends.
