Amiad Replacement Body O-Rings

Good rings, price seems high.

I don't quite see why the price (several dollars each) although the ring material is something unlike ordinary black rubber. With all the sand in our water I HAVE to have filters in front of the timers in my extensive drip system. This means Amiad High-pressure Filters because the water is always on. The filters last just about forever (not the case with the hose thread types in an always-on installation) but after some years in the hot sun the o-rings between the two halves of the body began to stretch and deteriorate and eventually let water through. I wish I'd gotten a couple of replacement o-rings (despite the price) after two or three years, to have on hand, and I wish I'd started replacing them sooner because it's a real pain in the neck trying to cram a stretched o-ring into its groove well enough so that it stays in place when screwing the body halves back together. The relief when I finally bit the bullet and installed new rings was terrific and the time saved probably paid for the few months of use I might have saved trying to seal the filter with the old stretched o-rings. We live in Big Ag country and our air destroys rubber in moments -- I'm going to try keeping my new rings in the refrigerator. After all, it may be some years before I need more replacements...
