CLEANING PARTS
It is recommended to clean all metal parts for oxygen service, regardless of Regulator Model
being repaired. There are several ways to clean components for oxygen service; the
following standards are recommended reading for more detailed information on methods and
processes:
• CGA G-4.1 “Cleaning Equipment for Oxygen Service”
• ASTM G-93 “Standard Practice for Cleaning Methods and Cleanliness Levels for
Material and Equipment Used in Oxygen-Enriched Environments”
• ASTM G-127 “Standard Guide for the Selection of Cleaning Agents for Oxygen
Systems”
For metal parts, Victor brand suggests using CCI Envirospray Liquid, used per the
manufacturer's instructions, followed by a hot water rinse and thorough drying. Additional
information can be found at
http://www.ccichemical.com.
DO NOT allow non-metal parts to come in contact with cleaning solvents. Cleaning solvents
can cause non-metal parts to swell and/or crack. To clean these parts, use a non-petroleum
based mild soap solution, followed by a thorough rinsing in water. Dry parts completely prior
to reassembling.
