Product information

This product supersedes product no: 5100201

Unitor cylinder regulators for acetylene and oxygen are designed for reliability and safety in use as part of a gas distribution system. The large adjustment knobs are red for acetylene and blue for oxygen for easy identification of gas type. Both contents and working pressure gauges are clearly graded in psi and bar.

All regulators are delivered with spare washers, hose connection for 1/4" and 3/8" gas hoses and instructions for use. Unitor regulators ensure a correct and stable working pressure with sufficient capacity for all types of gas welding and cutting work.

• Easy identification of gas types with colour-coded adjustment knobs

• Immediate identification of gas pressure with easy to read gauges marked both in psi and bar

• Full capacity for all types of gas welding and cutting work

• Designed for use with Unitor Acetylene gas cylinders

• Full conformance with EN ISO 7291 / 2503


For safety reasons we strongly recommend to perform annual checking and testing of the regulator, and to change the regulator every 5 years. For vessels under OCIMF SIRE VIQ 7, replacement of the regulators is mandatory after 5 years from date of manufacture.
