Push-Fit Adapter Fitting 1/4 in Bio-Based
This Parker 6366 56 60WP2 adapter connects 1/4 in and 3/8 in tubing with push-to-connect ends on both sides. It is made from bio-based nylon in white and suits vacuum applications. The fitting handles up to 230 psi and 200 Degrees F. Overall length is 1 5/8 in.
Practical limits of the push-to-connect interface
Push-to-connect joints seal without tools but rely on clean, round tube ends and correct insertion depth. The 230 psi ceiling means the fitting is not rated for high-pressure hydraulic circuits. At 200 Degrees F the bio-based nylon approaches its thermal limit, so continuous exposure near that temperature should be avoided.
What this replaces and when the jump is worth it
The adapter replaces threaded couplings or barbed fittings that need clamps and sealant, cutting assembly time on vacuum lines. It is not for systems that demand metal threads, higher pressure ratings or chemical resistance beyond the bio-based nylon spec. Buyers who need a larger bore or a different tube combination should look elsewhere.

Questions about this item
Which tube-size combination should I pick for my vacuum line?
The fitting joins a 1/4 in tube on side A to a 3/8 in tube on side B, so choose the matching pair for your existing tubing.
What does the 230 psi rating mean when the fitting is installed?
It is the maximum operating pressure the bio-based nylon body can sustain in vacuum service without leaking or bursting.
How does the push-to-connect interface affect the pressure limit?
Both ends use push-to-connect, and the 230 psi ceiling applies to the complete joint once the tubes are fully seated.
