Poly-Tite Fittings
Advantages
A compact brass compression ftting designed to speed any installation.
Body, nut and sleeve are furnished pre-assembled, ready for
installation. An exclusive acetal copolymer sleeve holds plastic tubing
where it belongs, even when the system pressure exceeds the tubing
burst point. Poly-Tite sleeves have superior resilience to resist creeping
and stress caused from compression. The black acetal copolymer
sleeve also resists ultra-violet ray attack and has excellent dimensional
stability. Poly-Tite nuts will rotate around the sleeve as it tightens to
prevent twisting and weakening of the plastic tubing. Poly-Tite fttings
can be assembled and disassembled repeatedly.
Materials
Bodies and Nuts: CA 377, CA 360, CA 345, 316 Stainless Steel
Plastic Sleeves: Acetal Copolymer.
O-rings: Buna N on chrome plated couplings
Viton on stainless steel couplings
Applications
Use with Parker Parfex® or other high-quality thermoplastic tubing for
pneumatic instrumentation circuits, lubricant and coolant lines, and
applications with other gases and liquids. For use with soft metal tubing
and nylon thermoplastic tubing, use brass sleeve and nut assembly
61PB.
Working Pressure and Temperature Ranges
Up to 150 PSI from 0° to +150°F with thermoplastic tubing. Up to 300
PSI from 0° to +175°F with soft metal 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 ftting and tighten
knurl/hex nut fnger-tight — plus one wrench turn.
Copper, aluminum and nylon tubing:
Brass sleeves are recommended. Insert tube until it bottoms in the
Poly-Tite ftting and tighten one wrench turn past fnger-tight.
Maximum allowable metal tube wall thickness for use with
Poly-Tite fttings:
1/8", 3/16" O.D. — no limitation, 1/4" O.D. — .035
5/16", 3/8", 1/2" O.D. — .049
Order
By part number and name.
Nomenclature
Part numbers are constructed from symbols that identify the style and
size of the ftting. The frst series of numbers and letters identifes the
style and type ftting. The second series of numbers describes the size.
Sizes
Tube sizes are determined by the number of sixteenths of an inch in the
tube O.D.
Special Fittings
Fitting confgurations and/or sizes other than those shown in the
catalog can be furnished. It is suggested that a print or sketch be
submitted with the inquiry.
