I've been a user of OMS equipment for several years and found the equipment and service to be more than adquate and satisfactory. As usual one reading posts here should assume incomplete and not necessarily unbiased information from ALL sources. John's response follows: Subject: Internet Response Relative to the comments on the internet. Burst Plug/Disc assemblies-The persons issuing statements regarding these assemblies leaking have a legitimate concern. About 2 years ago we received 120 manifolds with an aluminum seating washer. The aluminum washer due to galvanic reaction gradually lost its sealing capability resulting in small leaks in the burst Disc assembly area. Upon identification of the problem, we immediately respecified the entire burst disc assembly along CGA guidelines and specified an inert, Oxygon compatible washer. This rectified the problem. Most if not all of our OMS dealer base had been notified and offered these replacement washers at no charge. If we have missed anyone, we apologize, and would like to rectify this situation as soon as possible. OMS Manifold Valve O-Ring sealing method-Prior to marketing our valve we researched and talked with numerous O-Ring design engineers regarding the optimum method of sealing a high pressure valve: at the crossbar to valve body interface. It was determined after careful study that one of the safest and most reliable sealing techniques, is the captured O-Ring method presently utilized on all DIN 477 standard 1st stage regulators. OMS valves use the same, exact captured O-Ring sealing method. OMS Stainless Backplate/Harness System-If any OMS customers have experienced problems with webbing abrasion we invite you to call your local authorized OMS dealer for a no-charge fix. We stand behind our entire productline and want you to be happy with your equipment. My apoligies to Ronnie for posting this to both bbds. For most posts I agree with him. Have a pleasant.... Bill Pilicer PS If I understood my source correctly the OMS tanks are mfgd to be able to be cycled to 4000psi 10,000 times.
