Prestolok Fittings
Advantages
Ready-to-use compact one-piece ftting for use with most thermoplastic
tubing. This ftting is specially designed for low pressure circuits where
fast assembly, disassembly and reassembly is important. No special
tools are needed for assembly; just insert the tubing until it bottoms.
Prestolok is designed to be used with no tube support. Radial claws
on the stainless steel grab ring grip the tubing securely to provide
retention. Brass Male pipe threads come standard with a white acrylic
sealant pre-applied ("W" prefx) swivels are featured on all male
pipe threaded shapes for installation in tight places and for precise
positioning. Prestolok should not be used for live swivel applications.
The outside diameter of the tubing to be used with the ftting is marked
on the release button.

CAUTION: All current manufacturers of 85A PU tubing do not approve
the use of push-to-connect fttings with their product.
Testing has shown acceptable use with certain O.D – I.D. combinations.
Applications and service conditions vary and therefore the use of a
tube support may be required for any 85A PU tubing.
The following commercially available O.D. – I.D. 85A tubing sizes
require the use of a tube support regardless of application.
5/32” – 3/32” 3/16” – 1/8” 1/4” - .170” 1/4” – 3/16”
5/16” – 1/4” 3/8” – 5/16” 1/2” – 3/8”

Assembly Instructions
1. Cut thermoplastic tubing squarely, using Parker Tube Cutter
PTC-001. Be certain the port or mating part is clean and free
of debris.
2. Insert tubing into ftting until it bottoms. A slight twisting motion will
ease the insertion. Pull on tubing to verify it is properly retained in
the ftting.
3. To disassemble, simply push the release button against the body
and remove tubing.
4. It is recommended to trim the tubing after every disassembly to
insure a proper seal.
