A preassembled compact compression tting. An exclusive acetal
copolymer sleeve has superior resilience to resist creeping and stress
caused from compression. Poly-Tite nuts will rotate around the sleeve
as it tightens to prevent twisting and weakening of the plastic tubing.
Assembly Instructions
Polyethylene, polypropylene and vinyl tubing:
1. Cut tubing squarely–maximum of 15° angle
allowable.
2. Check that port or mating part is clean and
free of debris.
3. Insert tube end until it bottoms in the
Poly-Tite fitting and tighten knurl/hex nut
finger-tight — plus one wrench turn.

A preassembled brass tting, with sleeve machined onto nut.
During assembly sleeve breaks away from nut and creates a seal
on the tubing. No aring, soldering or other tube preparation of tubing
is necessary.
Assembly Instructions
1. Cut tube squarely and cleanly removing all burrs.
2. Grasp fitting. Do not remove nut.
3. Insert tube in fitting through nut until tube seats firmly against tube shoulder in body.
4. Grip tube firmly to prevent turning and tighten nut to finger-tight. Continue to tighten nut for
one and three-quarter additional turns (one and one-half turns for 1/2" size tube fittings) for a
positive, leak proof seal. During tightening a slight “give” will be felt. This “give” indicates the
sleeve has been sheared from the nut. It is not necessary to tighten the nut all the way down.
