Tube & connection
Record actual tube outside diameter (fractional inch or metric), wall thickness, thread standard, end configuration and installation instructions. Nominal sizes alone are not enough.
TECHNICAL RESOURCE / ENGINEERING REVIEW
Part-number interchange starts with the specification.
A similar-looking fitting is not necessarily interchangeable. Use this free worksheet to assemble the information needed for a documented, model-specific comparison.
Download blank review worksheet (CSV) ↓What an engineer needs to verify
Enter the original and proposed manufacturer part numbers in the worksheet. The blank download contains no approved equivalents: request our documentation for each exact combination before specifying or substituting any component.
Pressure & medium
Share design pressure and temperature, media, and any project ASME/ANSI class requirement. Obtain a rating for the exact proposed model; a class label does not establish equivalence.
Wetted parts
Confirm material grade and traceability. If NACE MR0175 / ISO 15156 applies to sour service, request evidence for the precise wetted components and service conditions.
Scope of testing
Compare drawings, certificates and test conditions, not appearance alone. Published family information does not establish interchangeability for every size or application.

Have a part number to compare?
Email both part numbers, a drawing and operating conditions to exports@arcellorcontrols.com. Sending an email is required; downloading the worksheet does not submit an inquiry. Ask for current certificates and tested scope before using any proposed substitution.
