OATEY 33858 – Frequently Asked Questions
1) Will the Oatey 33858 pipe clamp work on 20 gauge metal studs?
Yes. The Oatey 33858 insulating pipe clamp is made for 18 gauge or lighter weight metal studs, and 20 gauge is lighter than 18, so it falls inside that range. On anything heavier than 18 gauge the clamp is the wrong part.
2) What size pipe does the Oatey 33858 stud clamp hold?
It is the 1 inch version of Oatey's metal stud insulating clamp. Order the matching size to the pipe OD you are running; the smaller 1/2 inch clamp in the same family is drilled with 1/4 inch and 3/8 inch holes, so it covers small supply lines rather than 1 inch pipe.
3) Will a plastic pipe clamp hold up on a hot water or hydronic line?
The Oatey 33858 is rated for use on hydronic systems. It is molded polypropylene rather than metal, so it will not corrode where a steel clamp would, and it isolates the pipe from the stud instead of sitting metal to metal.
4) Do I need tools to install the Oatey 33858 clamp?
No tools. The clamp hand tightens into the stud punch-out and has tabs for adjustment, so a plumber can set pipe runs through a wall of metal studs without pulling a driver out.
5) Is the Oatey 33858 pipe clamp code listed for plumbing inspection?
It is UPC listed, which is what an inspector working to the Uniform Plumbing Code will look for on a support. It also carries patent #6,598,835.
6) How many Oatey 33858 clamps come in a bag?
They ship 25 to a polybag, which is the practical count for a multi-unit rough-in where you are supporting a run every few studs. Manufacturer part number is 33858.
7) Why use an insulating stud clamp instead of a steel strap through the stud hole?
Two reasons a plumber cares about: the polypropylene body separates copper pipe from the galvanized stud so you do not get dissimilar metal contact at every support, and it cushions the pipe so thermal movement does not telegraph as ticking through the wall. A metal strap does neither.
