OATEY 31212 3/4 in. x 260 in. PTFE White Thread Seal Tape

White PTFE tape like the Oatey 31212 is the standard-duty product for water and general threaded pipe joints. For fuel gas piping the trade uses the heavier yellow gas-rated PTFE tape, and that is what inspectors look for on a gas line. Use the white tape on potable water supplies, faucet and shower risers, and drain fittings with tapered threads.

It complies with Military Spec No. A-A-58092 and UL 31 RO. If your submittal or MRO spec calls out A-A-58092 thread sealing tape, the Oatey 31212 satisfies it, which is what usually clears it for government, healthcare, and education procurement.

The Oatey 31212 is a 3 mil, high-density PTFE tape with a density of 0.7 grams per cubic centimeter, and the high density is specifically what keeps it from tearing or stretching as you pull it around the threads. That matters on larger male threads where a thin, low-density tape tends to shred and bunch up in the thread roots instead of seating.

Tape and paste both seal tapered pipe threads, and they do it differently. PTFE tape such as the Oatey 31212 is dry, does not run or drip, and will not contaminate a fixture or a potable line, so it is the cleaner choice on finish work, chrome supply nipples, and anything you will have to take apart again. Pipe dope fills sloppier or nicked threads better and lubricates heavy black iron makeups. Plenty of contractors use tape on small brass and plastic joints and paste on large steel.

Yes, and it is the preferred sealant on plastic threads. PTFE tape like the Oatey 31212 adds no solvents and does not stress-crack plastic the way some paste sealants can. Wrap in the direction the fitting tightens, and hand-tighten plus roughly a turn or two with a strap wrench, since plastic male adapters split easily if you torque them like steel.

The 31212 PTFE tape is produced both carded for counter and retail sale and packaged bulk on spools for volume users. If you are stocking a truck or a maintenance shop, the bulk spool packaging is the one to ask for.

Order it as Oatey 31212. That is the manufacturer part number for the 3/4 inch by 260 inch white PTFE thread seal tape, and it is the number to quote if you are matching what is already on a shop shelf.
