OATEY 33856 – Frequently Asked Questions
1) Will the Oatey 33856 pipe clamp work on metal studs, or is it for wood framing?
The Oatey 33856 is made for metal stud framing, specifically 18 gauge or lighter weight studs. It hand tightens into place using the stud's punched hole, so no screws or straps are needed. For wood studs you want a nail-on or screw-mounted pipe clamp instead, since this one relies on a metal stud web to grip.
2) What pipe sizes fit the Oatey 33856 1/2 inch metal stud insulating clamp?
The 1/2 inch version carries both 1/4 inch and 3/8 inch holes in addition to the 1/2 inch size, so one clamp handles small supply lines as well as 1/2 inch tube. Useful on mixed runs where you have 1/2 inch water lines alongside smaller ice maker or hydronic tubing.
3) Does the Oatey 33856 clamp isolate copper pipe from the metal stud to stop noise and galvanic contact?
Yes. The 33856 is an insulating clamp molded from polypropylene, so the pipe never touches the steel stud. That keeps the copper separated from the metal edge and cushions the line against water hammer and thermal movement noise. The polypropylene body also will not corrode in a damp wall cavity.
4) Can I use the Oatey 33856 clamp on hot water or hydronic heating lines?
Yes, the 33856 is rated by Oatey for use on hydronic systems, so it suits heating loops as well as domestic hot and cold supply. The polypropylene body does the insulating, which is what lets it sit against a hot line without the metal-to-metal contact a steel strap would create.
5) Do I need tools or fasteners to install the Oatey 33856 insulating pipe clamp?
No tools and no separate fasteners. The 33856 hand tightens into the stud and has molded tabs for adjusting the position of the pipe after it is seated. That is the main reason crews use these over strap and screw on metal stud walls, since each support takes seconds.
6) How many Oatey 33856 clamps come in a bag, and what does one weigh?
They ship 50 to a polybag, which is how most plumbers buy them for a rough-in. Each clamp is listed at 0.012 in product weight, so a full bag is light enough to carry loose in a tool bag. Order by the bag, not the piece.
