Matheson Gas has used JJ Marc for years for cryo pump repair. They give us a quick turnaround and stand behind their work. When someone tells you it can't be repaired give them a call.

I have been working with Roger and JJ marc for over 10 years for cryogenic parts, hose gaskets, pump seals, shafts or valve assemblies. If it exists, Roger can get it. JJ Marc's most valuable thing I have learned is information. They have excellent knowledge of pumps and valves to help along the way. JJ Marc has awesome customer service that i would recommend to everyone. They are my first choice in the cryogenic industry.

I have been using JJMarc for over 25 years for my seal repair, pump parts, service and custom one off machining. Quality and service is at a level that’s hard to find. Whenever we have needed JJMarc, Roger has always been there to help us. I highly recommend JJMarc.
