OATEY 33877 – Frequently Asked Questions
1) What pipe size does the Oatey 33877 clamp fit?
The Oatey 33877 is sized for 1 inch pipe. It is a standard polypropylene support clamp, model 33877, sold six to a polybag, so one bag covers six hanger points on a 1 inch run.
2) Can I use these clamps on hot water or hydronic heating lines?
Yes, within a working range of 0F to 160F, and the clamp is specifically called out for use on hydronic systems. For anything running hotter than 160F, use a metal support instead.
3) Does this clamp let copper pipe expand and contract, or will it cause ticking?
The ribbed body holds the pipe without gripping it dead tight, so the line can expand and contract freely and cools faster. That same ribbing plus the plastic body cuts the transmission of water line noise into the framing, which is the usual cause of ticking and banging in walls.
4) Will a plastic pipe clamp corrode in a damp crawlspace or slab area?
No. The 33877 clamp is molded from polypropylene (gray), so there is nothing to rust or react with copper, and it does not corrode in damp locations the way a steel strap can.
5) Can I mount 1 inch pipe tight against a stud or joist with this clamp?
Yes. The clamp design is made to flush mount the pipe against walls and joists, so the run sits tight to the framing rather than standing off it.
6) Is a plastic pipe clamp or a metal strap the better choice for supporting water lines?
Use the polypropylene clamp where you want noise control and free pipe movement, and where a metal strap would corrode or react against copper. It holds to 160F, so it covers domestic hot, cold and hydronic runs. Go to metal support where the line runs hotter than 160F or where a code-required load rating on the hanger drives the choice.
7) How many Oatey 33877 pipe clamps come in a bag?
Six clamps per polybag. Each clamp weighs about 0.142, so a bag is light enough to carry a handful of them in a tool bucket for a full rough-in.
