OATEY 33940 – Frequently Asked Questions
1) What pipe size does the Oatey 33940 clamp fit?
The Oatey 33940 is a standard pipe clamp sized for 1/2 inch pipe. One clamp holds one 1/2 inch run, so size the quantity to your hanger spacing on the job.
2) Can I use these plastic pipe clamps on a hot water or hydronic line?
Yes, within temperature limits. The 33940 polypropylene clamp is rated for 0F to 160F and Oatey states it can be used on hydronic systems. For anything running hotter than 160F, use a metal clamp instead.
3) Will these clamps help with water hammer or pipe ticking noise in apartment walls?
They help with transmitted noise. The clamp is built to minimize transmission of water line noise into the framing, and the ribbed interior lets the pipe expand and contract freely rather than binding, which is what causes ticking in hot water runs. It is not a water hammer arrestor, so it will not fix shock from fast-closing valves.
4) Will a plastic clamp corrode against copper pipe?
No. The 33940 is molded polypropylene (gray), so there is no metal in contact with the pipe and no galvanic corrosion or rust staining, which is the usual reason to pick plastic over a steel or copper strap on copper tube.
5) Can the pipe sit tight against the stud or joist with this clamp?
Yes. The 33940 clamp design lets the pipe be flush mounted to walls and joists, so you can run 1/2 inch line directly on the face of a stud or along a joist without furring it out.
6) How many clamps come in a bag of Oatey 33940?
They are packed 100 to a polybag, which is why this one gets bought by the bag for rough-in work and MRO stock rather than one at a time.
7) Why does the ribbed inside of the clamp matter on a hot water line?
The ribs hold the pipe off the full inner face of the clamp. That lets the line cool faster and move as it heats and cools instead of gripping tight, so you get less creaking and less stress at the fittings on 1/2 inch hot runs.
