Use of O Ring Lub on plug for Pool Closing

[richmgreen]

Is it recommended to put O Ring lube on the Oring on the plug (see photo) when closing/winterizing the pool ?

Thanks
Rich

I always put teflon tape on the threads and any pvc parts to keep them from seizing up together

LASCO and others recommend Teflon tape NOT be used on PVC threaded fittings. For why read...

Assembling Threaded Plastic Fittings | LASCO Fittings

www.lascofittings.com

Don't wrap Teflon tape or Teflon paste or pipe dope to add bulk to or to lubricate the joint. Do use a sealant for threaded joints.

Teflon tape, Teflon paste and pipe dope is intended for metal pipe and fittings. Metal to metal fitting joints are more difficult to tighten than plastic; the surfaces tend to gall without the aid of such lubricants as Teflon or pipe dope. Plastic fittings do not need this lubrication.

When Teflon tape is wrapped around plastic male threads it adds to the strain and tensile stress. The tendency of most installers is to incorrectly wrap several thickness of tape around the male threads, increasing stain and stress further.

Teflon paste and pipe dope, just like Teflon tape, make threaded joints slippery. Their use on PVC fittings can be an invitation to over-torque.

I use lube on those. Be mindful that the lube will make it seem less tight than it is. You can shatter the return pipe if you crank down too hard.

Also, if you go too far the oring will likely smush away from the plug.

Yes I use lube on all the o-rings, I agree with everything @Newdude said!
