1 Lucky Texan Posted May 31, 2017 Share Posted May 31, 2017 is there a brand or part number for an asst. of HNBR or a/c 'appropriate', DECENT QUALITY o-rings available from amazon or NAPA or someplace DIYers can easily shop, that will work on our soobs? Not sure I need 400 o-rings, but 8 may not have enough variety of sizes. I seem to have bought an assortment of foreign-made crap o-rings that don't last more than a coupla seasons. thanx Quote Link to comment Share on other sites More sharing options...
Datsunrides Posted June 1, 2017 Share Posted June 1, 2017 Really the only sizes you need for a A/C system are #6, #8, and a couple #10. Usually the #10 go from the evap to compressor, #8 from compressor to cond, and the rest are #6. These are usually green or blue colored for 134A compatibility. I have got them from NAPA and also from auto A/C shops. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted June 1, 2017 Share Posted June 1, 2017 I've only matched from kits so I'm unsure on specifics. Did you try Subaru? I guess they only sell the hoses with orings on them and not the orings individually but I've never checked. I think I started a thread years ago about sizes but don't think anyone listed sizes.

DaveT Posted June 2, 2017 Share Posted June 2, 2017 Try industrial suppliers - MSCdirect.comMcMastercarr.comI have bought both packets of 100 and assortments from them. They also have different grades & materials.Ordinary o rings are very affordable, small ones, 100 only cost a few $. IIRC, most normal car size ones, they don't sell individual, but the price for whatever quantity [varies with the size] is not crazy, and you have lots of spares.
