Brian o-rings come in a great variety of materials that are rated by a durometer number. Generally, the higher the durometer number the higher the rating for pressure/vacuum. Buna N, and Viton are the materials used in most scuba spplications. This is because these materials have a wide range of chemicals they are resistant to. The durometer ratings for high pressure will be at least 80 but I do not have any specs. handy right now to give exact numbers. Any good o-ring supplier (try the yellow pages) will work with you on this. Plumbing 0-rings are just not worth the risk. What is your life and that dive vacation worth?

They are a big chain in Michigan and surrounding states. They deal in strictly hardware/plumming/paint ..etc. They carry Orings that match the ones in my Dive Rite Manifold. I was picking some replacement rings out when an employee said the Orings for sale are for low pressure fittings...and would not be safe for scuba. Any truth to this? They appear to be normal non-viton orings. I realize Orings come in different qualities...but aren't Orings....Orings? > > Input?? > > Brian > > > > > > > > "Wilderness is not a luxury, but a necessity of the human spirit, and as vital to our lives as water and good bread.
