replacement seals for pvc unions?

[Spar]

is there somewhere online that sells just the seals that are used in various pvc unions? i need to replace a couple and would be way too much work (and space limited) to replace the entire union.

I get replacement O-Rings from my local ACE/True Value Hardware store as they have a wide assortment of O-Rings on hand. I just bring the old ring with me and match it up to a new one. Most plumbing supply places also stock them. Otherwise, if you measure the outside diameter of the O-Ring and the diameter of the material, you can order them from Mc Master Carr. Just search for "O-Ring" then look at "Multi Purpose" followed by Silicone. http://www.mcmaster.com
