HR6 compressor o-rings (Page 1/1) pahardy AUG 14, 07:30 PM I don't know about the rest of you but I spent 148,000 Hours + - looking for the suction and discharge manifold 0-rings on the HR6 Compressor. So I hope this will help some of my Fiero friends who may be having the same problem. The o-Ring I found is from the Four Seasons downloadable O-ring book. This # 24615 listed for the "GM A6/DH6/HR6/V5 Service Valve o-ring" Must be a miss print. It fits the Suction and Discharge ports. Quest Auto part were happy to order them for me $1.29 each. I have not yet charged the system but I am confident these will do the job. randy86 AUG 14, 09:15 PM Not sure about everyone else, but I bought a universal kit a few years ago and just match the o-ring I am replacing with one from the kit. Make sure to oil it first before installing. Good luck! sricka01 AUG 16, 03:55 PM quote Originally posted by pahardy: I don't know about the rest of you but I spent 148,000 Hours + - looking for the suction and discharge manifold 0-rings on the HR6 Compressor.
