Thought I would share my PTFE gasket/Washer with yall.
I have been using a gasket I made the very same way as depicted on the photo's.
It shows no sign of ware and has never let me down once.
The gasket could be made to any size and works great for my VM extension pipe held together with a couple of OD's easy flanges.
Its very flexible and hard waearing, wont leech any baddies into our product and cheap to make...
Heres the materials you will need. You will also need a full roll of 10mm wide PTFE/plumbers tape.
A compass to draw the OD/ID of the washer would also help. (forgot to include them in the photograph...)
After cutting out the cardboard washer, you will need to cut excess plastic from your spool of PTFE..
This will help us feed the spool through the hole while wrapping...
Now, very carefully wrap the PTFE around the cardboard washer, taking care to overlap the tape 50/50. Keep wrapping the PTFE tape around the washer until it becomes a lot thicker.
It usually takes a whole spool. Heres one finished for this blow by blow... And heres the same gatket with one of OD's easy flanges sitting on top... The gasket will flatten out over time with use/heat, but it will still compress to give us a vapour free seal.
You could also use a copper washer made from thin sheet, remember to cut the ID hole of the washer first, then trim off the OD.
Got the idea for a copper washer from Myles... Thanks goes to Olddog and Myles...
@Beginners/Novices:
Only use PTFE tape to make this gasket.
Do Not try to substitute the PTFE for silicone, plastic, rubber, or any other non tested compound...
Hope it helps to make the hobby easier and safer...
