Ratcheting CinchClamp™ Tool
Sizes: 
Watts Ratcheting CinchClamp™ Tool is designed to be used 
with WaterPEX tubing and CinchClamp™ connections.
Specifications
Connections shall use Watts brass and poly-alloy crimp fittings 
and WaterPEX
Installation
All CinchClamps must be installed using a Watts CinchClamp 
Tool and in accordance with all installation guidelines.
– Make sure the WaterPEX has a clean, square cut end.
– Slide the CinchClamp over the WaterPEX.
– Insert fitting and position CinchClamp, allowing for approxi-
mately 
– Position the open jaws of the CinchClamp™ Tool over the 
tabs of the CinchClamp and squeeze. Allow the tool to ratchet to the next position. Repeat until the white indicator is 
completely visible in the view hole (approximately seven 
times).
– To release the CinchClamp Tool rotate the release lever on the 
side. It is very important to complete the cinch process 
before releasing the tool.
If connections are made in temperatures below 30°F, 
caution must be taken to pause between ratchets, allowing the WaterPEX to form a proper seal against the barb. 
Do not use the Ratcheting CinchClamp Tool to remove 
CinchClamps. This will cause damage to the tool,  
resulting in improper connections.

 MODEL  DESCRIPTION
  WPCCT-6  Ratcheting CinchClamp™ Tool
Watts product specifications in U.S. customary units and metric are approximate and are provided for reference only. For precise measurements, 
please contact Watts Technical Service. Watts reserves the right to change or modify product design, construction, specifications, or materials without prior notice and without incurring any obligation to make such changes and modifications on Watts products previously or subsequently sold.

Calibration
Do not use the Ratcheting CinchClamp™ Tool if it has 
been damaged as this may result in an improper cinch.
After repeated use of the CinchClamp Tool, it may 
require calibration. A calibration gauge is provided in the 
tool pouch. Follow these steps when calibrating a Watts 
Ratcheting CinchClamp Tool.
1. Ratchet the Ratcheting CinchClamp Tool to the closed position and hold. Use the calibration tool to gauge the jaw gap. 
Ideally, the jaw gap should be between 1.5mm and 1.7mm. 
If the 1.7 mm side of the gauge slides into the gap, then the 
jaw space is too large. If the 1.5 mm side of the gauge can 
not slide into the gap, then the jaw space is too narrow.
2. To adjust the jaw gap, turn the Ratcheting CinchClamp™ 
Tool on its side and locate the Phillips screw positioned on 
the ratchet arm. Use a standard Phillips screwdriver to raise 
or lower the screw. Raising the screw (counter-clockwise 
turn) will cause the jaw gap to increase. Lowering the screw 
(clockwise turn) will decrease the jaw gap.
