AD-8991 Teflon Tape is used to seal threaded pipe joints and fittings to prevent leaks. It is commonly applied on water, air and some gas lines in bathrooms, kitchens and industrial plumbing systems. The PTFE material fills thread gaps, ensuring a tight, long-lasting and leak-proof connection.

AD-8991 Teflon Tape works on most standard threaded metal and plastic pipes, including PVC, CPVC, brass and galvanized fittings. It is designed for plumbing, air and certain gas applications. However, always follow manufacturer or local code guidelines and avoid using on non-threaded or compression-type connections.

Typically, 3–5 wraps of AD-8991 Teflon Tape are sufficient for most household pipe threads. For smaller threads, use fewer wraps; for larger or worn threads, slightly increase layers. Wrap in the same direction as the thread tightening so the tape doesn’t unravel when you screw the fitting together.

AD-8991 Teflon Tape is best used as a preventive sealant on threaded joints during installation or reassembly. To fix an existing leak, first turn off the supply, disassemble the joint, clean the threads thoroughly, then wrap the ad-8991 teflon tape correctly and reinstall the fitting to restore a proper seal.

Yes, AD-8991 Teflon Tape is made from PTFE, which offers good resistance to heat, moisture and many common household chemicals. This makes it suitable for hot and cold water lines and general plumbing use. Always check system specifications and safety guidelines for high-pressure or specialized chemical applications.
