PEX Tools and Connection
Different types of PEX fittings
There are four types of PEX fittings sold on PexSupply.com. The first
is QS or compression style fittings, the second is ProPEX or expansion
style fittings, third is the SSC or clamp style, and finally the fourth
one is Sharkbite PEX Fittings.
The QS-Style fittings are compression style fittings and don't require a special tool. Therefore
they should be used for smaller applications, and one-time applications that don't require a lot of
connections. The QS-Style fittings include fitting assemblies to attach the loops of a radiant heat
system to a manifold.
The ProPEX fittings require the use of a ProPEX Expander tool and ProPEX Rings. These fittings come
in many varieties and include fitting assemblies to attach to a Radiant Heat Manifold. The Expander
Tool may be used for larger radiant heat jobs and PEX Plumbing applications.
The SSC Fittings or Stainless Steel Clamp fittings require the use of a Clamping tool and Stainless
Steel Clamps. The tool can be used on multiple fitting sizes with the use of the different size
clamps. There are many different types of PEX Fittings, valves, and manifolds (only for plumbing)
made for the SSC System. These fittings work well for a Radiant Heat System or a PEX Plumbing System.
A Radiant Heat Manifold can't be attached to loops of PEX Tubing using SSC Fittings
(Fitting Assemblies are required).
ProPEX Fitting Connection (For use with Expander Tool)
Cut the end of the tubing perpendicular to the length of the tube. All of the material or burrs
that are created from the cut should be removed. Slide the ProPEX ring over the end of the PEX
Tubing. The ring should be extended over the tube by 1/16".
Separate the two handles of the tool, and slide the expander head into the PEX until it stops.
Bring the handles together to expand the tubing. Remove the head from the tube and rotate a
1/8". Slide the tool head into the tubing in the newly rotated position and expand again.
Repeat the expansion process until the tubing and ring are snug against the shoulder of the
expander head. For ½" make 2-3 expansions, 5/8" make 5-7 expansions, ¾" make 7-9 expansions,
and 1" make 12-14 expansions.
When tubing is expanded, remove the tool, and insert the fitting. There will be some resistance
as the tubing slides over the fitting. The tubing and ProPEX ring must be seated against the
shoulder of the fitting to secure a proper connection.
Note: ProPEX connections can't be made for PEX-AL-PEX Tubing
Ref. Uponor Wirsbo Handbook
SSC PEX Fitting Connection (For use with Clamp Tool)
Clamping connections may be made on any brand of PEX Tubing. However, it may not be used on
PEX-AL-PEX Tubing. Clamps come in 3/8", ½", 5/8", ¾", and 1". These clamps all work with the same
clamping tool and may be used with the different sizes of PEX Tubing.
To make a clamp connection the PEX Tubing should be cut so a straight end is provided. Slide the
clamp over the end of the tube. Insert a SSC fitting into the tube so that the tube is fully
covering the inserted barb. The clamp should then be moved between 1/8" - ¼" from the end of the
tube. The opened jaws of the ratchet tool should be placed over the ear of the clamp. The tool
should then be compressed until a click is felt. The clamp is then locked in a perpendicular
position. The tool handles should then be compressed together to complete the connections.
The tool will release when assembly is complete.
Note: SSC connections can't be made for PEX-AL-PEX Tubing
Ref. Uponor Wirsbo Handbook
Compression Fitting Connections
Compression fittings may be used to make connections for PEX and PEX-al-PEX
tubing. Compression fittings do not require a special tool. The tables
below show the fittings required to make compression fitting connections.
