Part of my intent was to have a backup orings just in case one did not seal and when my lines do fail I was going to purchase additional orings to repair them similar to one in a post in the thread below.

Need to get ahold of some OEM lines and size the oring at ACE hardware and then buy a bag of vitons from McMaster-Carr that will hold up to the temperature and the fluid requirements. I'm in no hurry just has to be done in a manner I'm comfortable with, thanks...

FEP with Silicone Core—The FEP shell is chemically resistant like PTFE, but the silicone core makes these O-rings more compressible. Both the FEP and the silicone are made from FDA-listed materials, so if the shell wears away, your food and beverage process is still protected. These O-rings resist ammonia, animal and vegetable oils, and ethanol. Temperature range is -75° to 400° F. O-rings meet ASTM D2000/SAE J200. The FEP has a durometer of D55 (hard) and is clear; the silicone has a durometer of A70 (medium) and is red-orange.
