    Oatey's Great White for NPT Screw Fittings

    The manual for my Sta-Rite System 2 DE filter cautions against using "pipe compounds." It recommends the use of the following products to seal threaded connections:


    I realize that regular old pipe compound like Oatey's grey "Pipe Joint Compound" http://www.oatey.com/Plumber/Shared/Pro ... pound.html is a no-no since it's not safe for plastic pipe.

    I'm wondering if Oatey's Great White with PTFE is ok to use. I have a bunch left over from another project.

    http://www.oatey.com/Channel/Shared/Pro ... _PTFE.html

    "For use with water, steam, caustics or dilute acid lines of PVC, CPVC, ABS, cycolac, polypropylene, iron, steel or copper."

    Great White is rated for up to 10,000 PSI on liquids from -50F to 500F and is non-toxic and rated for potable water.

    I'd be using it on the threaded NPT connections of my filter and my Pentair Dynamo pump.

    It is fine to use. So long as it's compatible with PVC, which it is.

    Thanks! Are the filter body and the pump body made from PVC? That's what I was most worried about.

    They're made of a composite. Still no worry though.

    Re: Oatey's Great White for NPT Screw Fittings

    What about RectorSeal #5? I have a bunch of that too.

    This one rated for PVC but it's a little less friendly to other kinds of non-metal pipe. For instance, I wasn't able to use it on a drinking water filtration system because the fittings there were polypropylene.

    Will this one harm pump or filter bodies?

    Any opinions on whether it works better or worse than Oatey's Great White for pvc pool pipe applications?


    RectorSeal No. 5 http://www.rectorseal.com/index.php?sit ... uct_id=212

    "RectorSeal® No. 5® pipe thread sealant is a soft-set, slow drying compound which seals, lubricates, and protects threaded pipe and fittings. It can be pressurized immediately for piping up through 2" and 100 psi(for natural gas, air and water only) and is ideal for application with a wide variety of fluids and gases, including potable water applications. Recommended for use on threaded galvanized steel, iron, brass, copper, aluminum, stainless steel, polyethylene, fiberglass reinforced and PVC pipe. Not recommended for use with ABS pipe or Oxygen. Conforms to Federal Spec. TT-S-1732."

    I wouldn't use it because some items could be ABS or polypro.

    You should be able to call the manufacturer of the pump/filter and ask them. I doubt polypro, but ABS is rather likely.
