Stainless Steel Clamp Ring System
• One tool system
• Available in 3/8", 1/2", 3/4", 1"
• 15-year system warranty
1.
Measure and cut the tubing. Be sure you
have a square, burr-free cut. An uneven
or jagged cut may cause an improper
connection.
2.
Slide the stainless steel clamp onto
the tubing.
3.
Push fitting into the tubing until the
shoulder of the fitting is against the
end of the tubing.

4.
Position the stainless steel clamp so that
it is 1/8" to 1/4" from the end of the tubing.
Important:
An improperly positioned
ring may produce a weak condition.
5.
Position the open tool over the stainless
steel clamp ear at a 90° angle. Completely
compress the tool handles to close the
tool over the clamp ear.
6.
Remove the tool.
Note:
The crimp tool
will not release until the connection
has been made.

Recommendations for Making Sweat Connections with Zurn PEX XL (Lead-Free) Fittings
Zurn PEX fittings are made from a very low lead brass material. This
material can easily be sweated to copper tube or other copper alloy
components with a few simple precautions.
1. Thoroughly clean the surface that will be sweated. This means wiping
any dirt away followed by removing the surface oxide
film by mechanical means such as a wire brush, sandpaper,
or a sanding cloth. Do this just before you are ready to make
the sweat connec tion because the oxide film quickly re-forms
on the surface of the part.
2. Use a flux or paste that contains chlorine. Be sure that the flux or paste is
suitable for potable water systems. This is typically indicated by the product
being listed to NSF Standard 61.
Caution:
Do not allow these fluxes to come
in contact with plastic fittings or components in the plumbing systems.
3. Use a solder that is suitable for potable water plumbing systems.
Typically this will be a 95-5 Tin Antimony solder that is listed to NSF
Standard 61.
4. The XL material does not transfer heat as rapidly as copper does so it is
important to move the flame around while heating to assure even heating
without creating hot spots. If the XL material is over heated, it will turn
brown. If this happens you should disassemble the connection and start
over with cleaning.
5. Because the XL material does not transfer heat as rapidly as copper, it will
also stay hot longer once heated. Care must be taken once the sweat
connection is made to be sure the connection is not disturbed until the
solder has solidified. Careful application of a wet rag to shorten the
cooling time will minimize the possibility that solder will run back out of
the connection before solidifying.
6. Clean all remaining flux residue from the XL fitting and mating
component or tube.
