Use the fitting or device label and record every stated connection detail. Nominal size alone does not establish thread, connection style, material, or device compatibility.
Identification checklist
- Record the complete fitting/device number and the manufacturer name.
- Record every stated size, thread and connection designation.
- Separate a fitting, connector, valve, sensor and complete device before ordering.
- Match the exact model documentation rather than selecting by a similar-looking connection.
