PGP TipStepped hosetails on all models but the 110W fit several tubing sizes including 3/4", 1", 1.25" and 1.5". We often purchase 1.5" MPT to slip adapters in the slip size needed as a more professional alternative to hosetails. Consider also gluing unions in place when using glued joints instead of hosetails.
