Parker 6579 56 18WP2 Push-Fit Elbow
The Parker 6579 56 18WP2 is a push-fit elbow fitting designed for vacuum applications. It connects a quarter-inch tube outer diameter to a three-eighths inch NPTF thread. The body is moulded from bio-based nylon in white. It suits installers who need a quick, tool-free joint in fluid or air lines.
Thermals noise and power
The fitting carries a maximum operating pressure of 230 psi and a maximum operating temperature of 200 degrees F. As a passive component it draws no power and produces no noise. The pre-applied thread sealant is not included so the installer must supply their own sealing method. Pressure and temperature limits define the safe operating envelope.
Upgrade path and fit
This elbow replaces a compression or flared fitting where a push-to-connect joint speeds assembly. The jump is worth it when the system runs at or below the stated pressure and temperature ratings and the tube size matches the quarter-inch specification. Builders needing a different tube diameter or thread type must select another model.

Questions about this item
How do I install the push-fit elbow on 1/4 in tube and 3/8 in NPTF threads, and what step is often missed?
Push the 1/4 in tube fully into the push-to-connect side until it seats, then thread the 3/8 in NPTF end into the port; the step often missed is confirming the tube is fully inserted before pressurising.
What maintenance or replacement will the bio-based nylon fitting need over time?
Inspect the white nylon body and sealing surfaces periodically for cracking or discoloration from heat and chemical exposure; replace the fitting if any degradation appears.
Which limit appears first during sustained use — the 230 psi pressure rating or the 200 °F temperature rating?
The 200 °F maximum operating temperature is typically reached before the 230 psi pressure limit in hot-water or steam applications.
