Express Service Regulator Repair

Regulator Repair- is offered as a service to all Sigma-Aldrich customers. We offer this convenience in order to expedite the repair of your equipment. We are able to repair regulation equipment subject to normal wear such as replacement pressure gauges, seals, o-rings, diaphragm replacement, CGA fittings, needle valves, springs, etc.

• Please note that gas regulation equipment attacked by corrosion can rarely be repaired and is not covered under warranty. When using corrosive gases make sure you use the proper equipment for the gas and follow recommended purging procedures to avoid damage to equipment.

If you have a Sigma-Aldrich regulator that has been sent to us but cannot be repaired by our service center due to costs associated with the repair, damage due to corrosion or some other valid reason, we will offer you a new replacement regulator for your application at an affordable cost. This transaction will be completed through our Technical Service Department who will be notified by our Service Center.
