DERNORD Teflon (PTFE) Tri-Clamp Gasket O-ring - 2 Inch Style Fits OD 64MM Sanitary Pipe Weld Ferrule (Pack of 20)

Dernord products are legit and high quality. I wasted my money on gaskets from another seller that weren't really PTFE but a typical lowest price deception. I wish I had bought these first.

I expected the soft silicone ones and was hesitant. They are hard but with a water test, they do work fine and seal.

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.

They work great! They are stiffer than the original gaskets and are easier to assemble

Product works great and received it on 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.

They are great for my still. They make a great seal.

The inner diameter of the gasket is bigger than the outer diameter that it claims to fit. I’m assuming this is actually a 3” gasket that’s mislabeled as 2”.That being said, the material seems to be PTFE. Very rigid.

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.
