Blue Monster tape and plumbing supplies cover sealing pipe threads, joining PVC and preparing copper for contractors and do-it-yourself repairs. The general-purpose PTFE thread tape is thicker and denser. Your connection type determines which supply belongs on the job.
Blue Monster is supplied by Clean-Fit Products, a division of The Mill-Rose Company. Mill-Rose’s history began in 1919, and it specialized in brush manufacturing in 1925. The company moved to its present location in Mentor, Ohio, in 1965.
Match the tape to the connection
Thread tape fills the small gaps between mating pipe threads. Blue Monster PTFE Thread Seal Tape is the general-purpose option. Start with clean, intact threads, keep loose tape out of the pipe opening and follow the package’s application directions and wrap instructions.
The connection decides where sealant goes. A compression fitting seals where the ferrule seats; its threaded nut supplies the clamping force. Put sealant only where the fitting’s instructions call for it.
For gas-line work, Gas Guard is the Blue Monster PTFE thread-sealing tape specifically designed for gas lines. For a compound that stays soft, Stay-Soft is a PTFE-enriched, non-seizing pipe thread compound that remains soft.
Match PVC cement to the pipe and service
PVC socket joints use solvent cement to join the mating surfaces. 1 Step PVC Cement is listed in clear and blue versions. Match the cement to the pipe material and service, then follow its preparation and primer requirements.
Curing is part of the job. Pipe size, temperature and service conditions affect when a cemented joint is ready for pressure. Follow the cement label’s cure schedule before turning the water back on.
Prepare both copper surfaces
Copper solder joints need clean mating surfaces inside the fitting and outside the tubing. Power-Deuce cleans both surfaces without requiring a tool change.

Frequently Asked Questions
Can you use Blue Monster tape on gas lines?
Blue Monster Gas Guard is the PTFE thread-sealing tape designed specifically for gas lines. You shouldn’t assume the general-purpose tape has the same application just because both are thread tapes.
How do you use Blue Monster pipe thread tape?
Apply Blue Monster thread tape to clean, intact male pipe threads, keeping it clear of the pipe opening. Follow the package instructions for wrapping direction and number of wraps. Tape fills gaps between mating threads; it can’t fix damaged threads.
What is Blue Monster PTFE thread tape?
Blue Monster PTFE thread tape is a general-purpose pipe thread sealant with a thicker, denser construction. You use it to fill the small gaps between mating pipe threads on connections that call for thread sealant.
Can Blue Monster compression seal tape stop a leak without shutting off the water?
Blue Monster compression seal tape is designed to stop leaks under pressure without shutting off the water source, with emergency and long-term applications. You still need to check its directions for pipe compatibility and pressure limits before treating it as a repair for your particular leak.
