I believe the term "plumbers tape" has been used for many years to describe the perforated glavanized strap used to hang piping. I heard the phrase used this way many years prior to the advent of teflon. RobertTaylor21 (talk) 23:02, 2 March 2008 (UTC)[reply]

"It has multiple uses including restorative dentistry."??? Looks like an odd sort of error to me.

"The yellow tape for gas lines is thicker. White tefon tape should not be used for gas lines." was deleted as unsourced, but is true. So let's find a source?

I also deleted the category "adhesive tape" (since it isn't) and added back in "plumbing". Huw Powell (talk) 23:18, 17 August 2008 (UTC)[reply]

Is "99% PTFE" sufficient to be "free from grease" for oxygen-use compatibility? It's a little hard to imagine 1% fuel, diluted in 99% inert thermal mass, being capable of elevating the whole temperature enough to react vigorously. Perhaps with hot gas from sudden adiabatic compression pre-heating the tape, then significant combustion can occur? jimswen (talk) 21:56, 19 July 2009 (UTC)[reply]

ASTM G93 don't specify a special type of PTFE tape to use with oxygen applications — Preceding unsigned comment added by 209.128.18.74 (talk) 14:05, 22 September 2013 (UTC)[reply]

Electrical non-conduction

I've read that PTFE tape also acts as a barrier to electrolytic damage which can occur when two metals e.g. iron and copper are in contact with one another, thus preventing corrosion in central heating systems. —Preceding unsigned comment added by 92.11.144.4 (talk) 17:11, 3 February 2010 (UTC)[reply]

Food safety

Are there any considerations regarding food safety with respect to thread seal tape (... i.e. when using thread seal tape with water pipes in a kitchen)? --Abdull (talk) 22:13, 26 July 2012 (UTC)[reply]

There are several grades. A grade for potable water supplies is required by most standards. This isn't different tape as such, it's a quality issue to guarantee absence of impurities. Andy Dingley (talk) 22:39, 26 July 2012 (UTC)[reply]

Tapered pipe threads

"Thread tape is appropriate for use on tapered threads, where the sealing force is a wedge action.[1] Parallel threads will not seal effectively with or without tape."

The first sentence may be true, but the second is either false or at least misleading. I've achieved effective seals many times using pipe tape on parallel threads. In fact, both of the photos showing the use of the tape show it being used on parallel threads. Also, the citation [1] leads to a 404 error. 69.251.37.117 (talk) 19:53, 13 January 2013 (UTC)[reply]

False

"It also protects the threads of both pieces from direct contact with each other and physical wear..."

This is not what happens. The tape cannot prevent metal-on-metal contact since it is designed to fill any gaps between the thread's peaks and troughs (this is what makes it air/water/gas proof) and is too thin and weak to even resist lightly tightened connections from 'grinding through' to make metal-metal contact. Using too little tape won't prevent leaks, using too much will just clog up the threads and not be a strong fit (too little amount of threads are engaged) because the tape acts like an imcompressable fluid if it is not squashed outwards. Also, if there is no metal to metal contact (friction with elastic deformity) then the pipe connection will loosen in the future... it is an anti-seize tape afterall. 210.84.5.219 (talk) 09:17, 23 March 2024 (UTC)[reply]
