Hello their fellow pressure washers,
Yes, the o'rings go out in the quick couplers but that is not the big problem. We buy o'rings at .03 ea. 500 to a bag. And as far as o'rings go, we have found the Buna are much better than viton for hot water. We have tried them both and vitons don't hold up and tend to get brittle and break into pieces. The problem is inferior quality quick couplers and the plugs. Some manufacturers use a softer brass for their couplers and some manufacturers make plugs that are not hardend steel. Either one of these on their own is a problem but the combination of both is definately a problem. Just like spray nozzels that are not made of hardened steel. The softer brass couplers tend to splinter when continually connecting and disconnecting. These splinters get into the ball bearings and make it difficult and almost impossible to connect and disconnect. The softer steel plug tends to mushroom and even compounds the problem. Since we have been using surface cleaners and are now constantly connecting and disconnecting, our couplers are getting constant useage throughout the night. We are now using only Adams couplers and plugs. We have found they hold up the longest. We use WD-40 on our couplers when needed, however, at 3,500 psi and 200 FAH, we go through 1 or 2 O'rings per unit, per shift. We try to monitor the plugs, since a worn plug can cause the o'ring and coupler problems. Anyway, Since you asked, that is the problem we have encountered with quick couplers and what we have done so far to resolve the problem. Best to you all in your business!!!!!!!!!
