A fitting order should describe every connection, not just the largest diameter. Elbows, reducers and tees can have different arrangements even when they share a general name. Use the approved drawing or materials schedule to state the exact configuration and quantity.
Describe each end consistently
Record the fitting shape, size of each end and specified connection method. Keep the diameter convention aligned with the approved copper-tube list. A reducing tee described by one size leaves two connections unresolved. For unusual geometry, attach the relevant drawing detail rather than asking the supplier to interpret a rough verbal description.
Check the material and application
Include the approved material and HVAC/R application requirements. A fitting that appears to fit a tube is not automatically suitable for the specified service. Record any proposed substitute and obtain technical approval before purchase. Count the required pieces from the current drawing revision, then confirm the exact supplied configuration and availability with the branch.
A practical enquiry example
For a reducing tee, describe the size at each connection rather than writing only the main-line diameter. Add a drawing reference where the branch orientation matters so the intended fitting remains unambiguous.
Enquiry checklist
- Fitting shape and all end sizes
- Connection method and size convention
- Approved material and application
- Quantity from the current revision
Is one diameter enough to order a reducing fitting?
No. State each connection size and the configuration so the supplied fitting can be checked against the drawing.
Discuss your requirement with Refco
Prepare the approved references and quantities, then contact the branch to confirm availability and collection details before visiting.
