Seal plastic fittings by wrapping the thread with Teflon tape. Go around the fitting two or three times, then pull the tape tight to break it off. 2. On metal tapered fittings, coat the threads with paste-type pipe sealant, also called pipe dope.
RectorSeal T Plus 2 pipe thread sealants are a non-setting, multi-purpose compound which contains PTFE, plus synthetic fibers to create a stronger seal. Recommended for use on threaded galvanized steel, iron, brass, copper, aluminum, stainless steel, polyethylene, fiberglass reinforced, PVC, CPVC and ABS pipe.
Thereof, Can you use Teflon tape on PVC pipe?
Don’t use Teflon tape, Teflon paste or pipe dope. … 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. When working with threaded plastic fittings do use a proper sealant.

Also, Is pipe thread sealant better than Teflon tape?
Pipe joint compound is easy to find, fairly simple to use, and inexpensive. It works with all types of pipe and fitting materials, and it produces a strong seal. Pipe dope is generally stronger seal than Teflon tape, which is why plumbers and other professionals use it rather than tape for seals that are permanent.
How does pipe thread sealant work?
Whether you use pipe dope or PTFE tape, pipe thread sealant is essential for any threaded pipe application. Thread sealant serves two purposes: it creates a liquid-tight seal by filling gaps in threads and it makes assembly and disassembly easier by lubricating the threads.

Plastic fittings do not need this lubrication.
When should you not use Teflon tape?
