(Teflon) PTFE 3" Tri Clamp Ferrule Gasket Sanitary, Pressure Formed Seal (FDA Certification)

Needed for october, ordered from other website (*cough terpp cough*) and when theres didnt show up for 10 days! I ordered from these guys. Fast shipping same ptfe gasket that everybody has. Anyone doing subzero extractions needs these. Buna-N/Viton whatever you call it, breaks down at temps lower than 0F, leaving little black specks in your end product. Along with breaking down over time and needing to be replaced because of the isopropyl alcohol everyone uses to clean them. PTFE last forever. Just dont overtighten these, they will stretch and permantently leak. And you will end up having a set like i have just for cleaning
