Watts WP9S-16 – Frequently Asked Questions
1) Are Watts Cinchclamps stainless steel or copper?
Stainless steel. The WP9S-16 clamp body is stainless, not a copper crimp ring, so it suits potable water and hydronic runs where corrosion resistance matters. Note that stainless clamps install with a cinch tool, not a copper crimp ring tool.
2) Can I use a copper crimp ring tool on the Watts WP9S-16 stainless clamp?
No. A cinch clamp closes by compressing a raised ear with a cinch (pinch) tool; a copper crimp ring tool squeezes the ring uniformly around the tube and will not set this clamp correctly. Use the cinch-style tool sized for 1 inch clamps.
3) Is the Watts WP9S-16 Cinchclamp Buy American Act compliant for a government job?
No. The WP9S-16 is listed as not Buy American Act compliant, so it will not satisfy a federal or BAA-flagged public works spec. On those jobs you need a domestically sourced clamp instead.
4) Does the Watts 1 inch stainless Cinchclamp need to be lead free certified for potable water?
Lead free certification does not apply to this part. Watts lists it as not in scope for lead free, which is expected for a stainless steel clamp: the clamp squeezes the tubing onto the fitting and is not a wetted brass component. The lead free requirement falls on the fitting and valve bodies in the joint.
5) Is the Watts WP9S-16 sold individually or in bulk?
It ships bulk, which is how these clamps are normally bought for production plumbing where you are setting dozens of joints a day. There is one model on the line, WP9S-16, the 1 inch stainless Cinchclamp.
