We do stock a few generic replacement parts such as hoses and O-rings, but in general our answer has to be "probably not" for most BC and regulator parts from these popular brands. We know it's frustrating; some dive equipment brands do not believe the consumer has the right to repair using concerns about liability or safety as their reason for prohibiting the retail sale of their branded individual replacement parts to consumers. The good news is that we agree the consumer has the right to repair and our Dive Gear Express policy is to sell individual parts for most brands we currently stock.
