Making a Good CrimpRing

 Connection 

n

1.  Cut the pipe to length, making sure that you have a good square 

cut. A rough, jagged, or uneven cut will result in a weakened 

joint. 

2.  Next slide the correctly sized CrimpRing

 over the end of the pipe 

and down about 2".

3.  Then slide the pipe over the fitting until the pipe touches the fit-

ting shoulder.

4.  Now slide the CrimpRing

 over the end of the pipe until it is 

1

8

to 

1

4

" from the end of the pipe. This positions the ring so that it is 

directly over the two ribs closest to the end of the fitting. 

5.  Now position the tool so that it is at a 90° angle to the pipe, and 

its jaws completely cover the ring. 

6. Close the jaws completely.
7.  Check to see that the “Go” slot of the Go/No-Go gauge slides 

across the CrimpRing

. If the CrimpRing

 doesn’t fit through the 

“Go” slot then the ring wasn’t compressed sufficiently. Cut out 

the joint, calibrate the tool, and make a new connection.

Installer Tip 1.

 Try a slight squeeze of the CrimpRing

 with the channel-

lock pliers to keep it in place. Then you use your crimp tool to make the  

final connection. You’ll find this especially  helpful in vertical installations.

Other ASTM F2098 and F1807 Crimp Ring may be used. 

Follow manufacturer's instructions carefully.

1.  Check each connection by pushing the crimp gauge onto the 

crimped copper ring at the appropriate “Go” slot. If it won’t fit 

through, the ring wasn’t compressed enough. If the ring fits 

through the “No-Go” slot, the ring was compressed too much. 

If your connection fails this test, cut out the bad joint and start 

over. 

Don’t try to run it through the crimp tool a second time. 

If 

the gauge “hangs up” where the tool jaws closed (you’ll see a 

small mark there), test the joint at 

a different point before you fail the connection and make 

the connection over.

2.  You must hold the gauge at a 90° angle to the ring to 

perform a good test.

3.  Always check to make sure you’re using the right size 

opening in the gauge for the size  pipe you’re installing.

4. Push the gauge right onto the crimped ring; don’t slide it! 
5.  Don’t change the gauge opening. It is manufactured to 0.002 tol-

erance to help protect your good reputation. 

Buy a new gauge if your old one is damaged.

How to Test a CrimpRing

 Connection

1.  Fitting Shoulder location.
2.  Pipe is cut square and stops at the fitting shoulder.
3.   CrimpRing

 is positioned 

1

8

"–

1

4

" from end of the pipe, 

directly over two end ribs of fitting.

4.   CrimpRing

 is evenly compressed over the pipe, and shows no 

evidence of uneven distortion.

5.  The WaterPEX

®

 material is uniformly compressed between the 

brass ribs, resulting in a leak-free, quality joint.

Using a CrimpRing

 Gauge 

n

Using the CrimpRing

 Gauge (Go/No-Go gauge) helps ensure a 

quality joint. It has six openings, two for each size of pipe it fits. 

These are for 

3

",

2

", and 

3

" (10, 15, 20mm) pipe sizes. See the fol-

lowing illustrations for guidance on how to use this important tool. 

Always check every joint you make.

Making a Good Cinch Clamp Connection 

n

Place PEX cinch clamp nub between tool jaws and ratchet the 

clamp until the PEX Cinch Clamp Tool auto-releases. This action 

will assure that the PEX cinch clamp is fully clamped.

These connections ar

e a cinch to make.

Our new CinchClamp boldly goes wher

e those other fittings can’t — mainly 

into tight, hard-to-reach spaces. With a unique “tab” design, there is no need 
to get a tool around the entire fitting. Simply press the tab closed with the
CinchTool

and the connection is complete. 

This design offers a positive mechanical connection, ensuring the PEX is 

uniformly compressed against the fitting. The ratcheting CinchTool only releases
when proper assembly is complete. No guess work is needed to determine if the
connection has been properly made. 

The unique CinchClamp design makes the new CinchTool dramatically 

simpler and easier to use. One tool installs all sizes from 3/8" to 1".

The CinchClamp connection 

system needs only one tool 

for all clamp sizes.

CinchTool measures 11"L x 3"W x 3/4"H

Why it’

s a cinch:

Ratcheting tool provides easy one-tool assembly.

• Connections can be dry-fit. 
• Connections can be made with wet tubing.
• Final connections take only seconds.
• CinchTool only releases when connection is 

complete, ensuring a perfect connection.

• No calibration required on the CinchTool.
• Can visually verify whether connection 

is completed – tab of clamp is 
“pinched”.      

• Connection rated to 160 psi 

@ 73°F; 100 psi @ 180°F.

• Clamp is an interlocking ring, 

forming a complete 360°
uniform, watertight seal.

• Corrosion resistant, 

annealed stainless steel.

• Uses ASTM F1807 brass or ASTM F2159 plastic insert fittings (plastic for 

potable systems only).

the CinchClamp is applied.
