Dixon Valve TTB75 PTFE Industrial Sealant Tape, -212 to 500 Degree F Temperature Range, 3.5mil Thick, 520 Length, 3/4 Width, White

I mean its Teflon tape. What is there to review? It seals threads and helps prevent leakage.

Very generous amount is provided

Its okay. It does the job. It IS very thin, so cutting each piece youll use with a small pair of scissors is highly recommended. Having worked as a plumber for some years back in the late 1970s the tape we used was a bit thicker and never once did we cut it. it did have stretch to it, but all you had to do with that pretty much was pull it tight and yank it. Try that stunt with this gauge of tape and I think youll find that youre going to need the more than ample supply provided. the description DOES read Industrial, so having not worked in the trade for so long I wont attempt to call this one. It IS also on the thick side measuring side to side. For shower head installation lets say, it might be a bit much. I dont know. Improvise. It does the job wont break the bank you MIGHT find Sealant Tape at the 99 Cents Only Store, but I needed it TODAY. So...

Good quality Teflon.

good

TLDR: Its so thin its basically see through, the width is smaller than advertised, and its a fifth the weight it should be. The description says its 3.5 mils/0.09 mm thick by 3/4 wide by 520 long. Using the density of PTFE (2.2 g/cm^3) the tape alone should weigh about 50 grams, but on my scale the tape AND spool weigh only 11.05 grams, thats 1/5 the weight it should be. Im not gonna bother measuring the 43 or so foot length advertised but the width is not 3/4 inch either, my caliper shows its around 0.70 which seemed odd until I switched to millimeters and its exactly 18.0 mm wide. Assuming the length isnt too far off, this would mean the thickness is not 3.5 mils but closer to 0.8 mils or 0.0008 inches (0.02 mm) but I dont have a micrometer precise enough to measure this. Sure its a cheap roll of Teflon sealant tape made in China, but this is just ridiculous.

3/4 inch is great for most of plumbing.

It’s plumbers tape, not much to say. Got a leaky faucet, shower head, hose attachment, (anything that has water running through it and a screw on attachment)? Just unscrew whatever it is. Wrap the outside part of the pipe (with the ridges to screw on the attachment) right onto where you’ll need to screw the attachment on, wrap a couple times to make sure you got the whole ridged part (don’t go nuts and make it thick) just enough to cover it, rip the end off, screw the attachment back on. Lots of directions for a very simple application. No house should be without a roll of this for leaks, replacements, etc. And depending on the age of your attachments, you may need a good wrench to get them off. In that case, don’t wrench off the whole pipe, hold it while you struggle. Once it’s off, clean with CLR and a wire brush before putting back on. Get the rust and water calcium off. Soak them if you need to, it can’t hurt. THEN use the tape to reattach it. This is a staple to keep under the kitchen sink or in the junk drawer. You always eventually need it.

Works as expected

It was perfect as described (plumbers tape) did the job
