It annoys me that people persist in using tape on caravan park taps before screwing their fittings and hose on . The rubber washer inside the fitting does the sealing and not the tape ! The easier the fitting screws on the better the seal !

 I was thinking the same my self  as we have just this morning left the Ocean Beach CP "Denmark WA"     Various water taps all having PTFE Thread Seal tape on the thread at our hose connection point.

The hose connection thread on a Tap outlet,  is a Parallel Thread   designed to take the Compression Fitting on the end of the Hose.   As Hawke7 says above 

It's the  Washer inside the Hose end fitting that does the Sealing.

Carrying  a few spare washers is a must for me.

   The PTFE thread seal tape, and the various other  Pipe Fitting Thread seal products are designed to  work on Tapered Threads usually

maybe they are scottish, to be sure ;to be sure; to be sure.LOL

G'day all haters of the Teflon Tape on tap nut threads!

It's all OK I found a bloke using it in a park a few months ago and decided to approach him and explain that if the washer is in good nick you are wasting time and money using tape.

Or even if the washer is gone it's still a waste of time.

 I even offered him a spare washer.

Well, he gave me a lesson in manners, plumbing and aerobics, advising me that I should place my head in what I would consider a rather difficult position although I didn't try it.

After all, you don't have to try everything to know it's not possible, or comfortable.

So now as frustrating as it is watching someone put the tape on, in future I'll just watch - or maybe not!

Keith....

just do what I do

get out my die nut run it up the thread 

cleans it off real easy screw on connection all good

Gromet you are a genius

what is the thread and what size die nut do I need please?

 You need two - BSP ¾" and 1" - The ¾" one fits ½" taps and the 1" one fits ¾" taps.

Just use a wire brush to get the telflon tape off the threads, although we never find it a problem to screw the connection with the tape in place.

 Actually,     "PTFE"     thread seal Tape,     also has lubricating properties in it,  to allow  "Tapered" threads to be pulled up tight for better sealing.

It's use on the Taps we are talking about should not usually  be necessary.    

One problem that can arise from this practice,  is the tape when it is put on badly or gets frayed.      Small pieces get detached and are washed through the hose into the system.     These bits of PTFE can then get trapped in the seats of E.g. Non Return valves, Pressure Regulators, Filters, Taps and other plumbing gear, preventing it sometimes from  working correctly.

How often have I come across problems in fluid and pneumatic systems that are faulty. The culprit is found  to be a tiny piece of PTFE tape trapped in the seat of a valve unit.

I've been using these for the past couple of years, great product, no tape needed.

 The problem if you change over to hoselink is that some of the newer parks have the tap that already has the click on adapter as part of the tap, tho maybe there is an adaptor that can click onto the tap so you can then use the hoselink fitting.
