Jlab Export is a leading Teflon Manufacturer,and suppliers in India
PTFE thread seal tape is wound onto male pipe threads before a joint is screwed together. It fills the small gaps between the threads and lets the fitting turn tighter without galling. This roll is 1/2 in wide and 236 in long, about 6 m, and the PTFE is chemically inert.

Plumbing and Pipe Fitting Practicals
Plumbing and fitting students use the tape on threaded steel pipe. A length of pipe is held in a Pipe Vice and threaded with the Pipe Threading Tool. The tape is wound on clockwise, seen from the pipe end, and a fitting is screwed on and tightened with a Pipe Wrench. The joint is then filled with water and checked for weeping.
In the refrigeration lab, teachers use the tape to show where thread sealant belongs and where it does not. Taper threads on gauge ports, drain plugs and water connections take tape. Flare joints made with the Flare Fitting Set seal on the brass cone face and are put together without it.
Frequently Asked Questions
Which way should PTFE tape be wound?
Wind it clockwise as you look at the end of the male thread, the same way the fitting turns on. Tightening then smooths the tape into the threads instead of pushing it off. Keep the tape flat and slightly stretched as you go.
How many turns of tape are needed?
Two or three turns cover most pipe threads, and coarse or worn threads may need a few more. Leave the first thread bare so that no loose strands of tape get into the pipe.
Should PTFE tape go on flare fittings?
No. A flare joint seals where the flared pipe end meets the cone of the fitting, and the nut threads only pull the two together. Tape on a flare can stop the faces seating, and shreds can get into the refrigerant circuit.
What if a taped joint has to be undone?
Unscrew it, pick the old tape out of the threads and clean them with a brush. Wind on fresh tape before the joint is put back together. Tape that has been crushed and turned back will not seal again.
What temperatures can the tape handle?
The tape covers -450 °F to +500 °F, so hot water lines and cold refrigeration lines are both inside its range. PTFE is also chemically inert and does not corrode.
