DERNORDTeflon (PTFE) Tri-Clamp Gasket O-ring - 2 Inch Style Fits OD 64MM Sanitary Pipe Weld Ferrule

Used them to try and seal between a keg fitting and a 2" TC, wasn't flexible enough to get the job done.

Did not accurately fit according to size description. Tried to file down to size but didn't work.

I have a Spike Brewing CF5 and the EPDM or rubber (black) gaskets would get bent out of shape over time. I was using one of these PFTE O-rings on the racking arm to turn it ever so carefully as to not spill my beer; when close transferring into a keg. It worked so well, never lost its shape and held a leak free seal (with food grade gel) that I decided to buy all 1.5" and 2" PFTE O-rings from Dernord. While typically PFTE is supposed to hold a slightly less seal I have had no issues using these. I also ferment under pressure at about 10 PSI. Glad I purchased them. Seems they will last a long time.

I replaced all silicone gaskets with teflon ones due to concerns of chemical evaporation and contaminants from silicone. Teflon gaskets are more rigid and needs better compression on clamps, but as the result you get a cleaner product. So, as i mentioned I replaced silicone with teflon, i have no I have leaks and very happy with the result.

I ordered a set of five as I needed one for an addition to my brewing equipment and its good to have a few extra on hand. I've purchased these before and had good luck with them.These are a good bit thinner than my previous set and don't seal in the groove of the ferrule, even with the clamps torqued down. Which brings me to my next review on their 2" tri clamps...Yep the quality is slipping there too.
