OATEY 38708 – Frequently Asked Questions
1) What is Oatey pipe guard used for on a plumbing rough-in?
Oatey 38708 pipe guard is a 200 foot roll of red polyethylene sleeving that wraps copper or other metallic tubing where it passes through concrete, masonry, framing, or backfill. The poly barrier keeps the pipe from contacting dissimilar material, and the red color marks the run as hot water line for anyone opening the wall or slab later.
2) Does polyethylene pipe guard stop copper from corroding in concrete?
That is exactly the job. Polyethylene is inert against the alkalinity in concrete and mortar, so sleeving the copper with the Oatey guard before the pour keeps the cement from attacking the tube and lets the line move slightly with thermal expansion instead of binding in the slab.
3) Is the red Oatey pipe guard for hot lines and blue for cold?
Red is the hot side by convention on a two color pipe guard system. Oatey 38708 is the red 200 foot roll, so order it for your hot water runs and use the blue equivalent for cold if you want the lines identified by color in the slab or wall.
4) How thick is the Oatey 38708 pipe guard material?
The polyethylene wall runs 4 mils. That is thin enough to slide and wrap tight around tubing and elbows by hand, and it is a separation and identification barrier rather than an insulating or impact sleeve. If you need mechanical protection through a stud plate, use a nail plate as well.
5) Can pipe guard be used on PEX as well as copper?
The Oatey guard is a flexible polyethylene sleeve, not a sized fitting, so it wraps PEX, CPVC, or copper alike. On PEX it is most often used for color identification and to isolate the tubing where it passes through framing or slab. It is not a substitute for a rigid sleeve where code calls for one at a foundation penetration.
6) How much pipe will one roll of Oatey 38708 cover?
One roll covers 200 feet of run, and it ships at about 1.75 pounds, so a single roll handles a typical residential slab rough-in for the hot side with margin for overlap at fittings. For multifamily or a commercial floor, count your hot line footage and order rolls accordingly rather than splicing short pieces.
