What is thread tape?
Thread seal tape tape commonly used in plumbing for sealing pipe threads. The tape is sold cut to specific widths and wound on a spool, making it easy to wind around pipe threads. The purpose of plumbers thread tape is to lubricate the area being tightened which allows for a deeper seating of the threads which ultimately assists in the ease of unscrewing and tightening at any time.
Tips for Using Thread Tape
Tape and dope are equally reliable for sealing pipe threads. The main advantage of tape is that it won’t smear onto your hands or tools and end up on the carpet. Here are a few plumbing tips for thread tape:
- Cheap tape works fine, but the thicker stuff (often pink for water, yellow for gas) is easier to handle and tears more neatly.
- Unlike plumbers dope, thread tape is for pipe threads only. Don’t use it on compression or other connections.
- How many times should you wrap the tape around the pipe? There are no rules, but the most common answer we’ve received from pro plumbers was three.
- Always wrap the tape clockwise around the threads. Otherwise, the tape will unwrap as you screw the joint together.
The main tip and trick to getting plumbers tape on correctly is to wrap it around the pipe in the proper direction. Now when pipe is turned into the fitting, the friction of the mating threads should work to tighten the tape around the pipe,
