Copper U-Tube With Nuts
Copper U-tube assemblies with threaded end connections, available in three listed UNF thread configurations. Compare the product photos, connection sizes and dimensional drawing to select the assembly for your refrigeration component requirement.
Product Overview
Product: Copper U-Tube With Nuts
Tube: Copper, U-shaped configuration
Thread options: 7/16"-20UNF, 5/8"-18UNF and 3/4"-16UNF
End sizes: Matching D1 and D2 thread specifications in each listed option
Selection: Confirm both end connections and the required installation dimensions
U-Shaped Connection Assembly
The formed copper tube incorporates a return bend, bringing the two connection ends into a U-shaped arrangement. The product images show the tube profile, nut connection and external threaded end. Buyers can compare the complete assembly with the connection layout required by their equipment.
A matching thread designation at D1 and D2 does not by itself describe every aspect of the mating connection. Use the product photos and drawing together to confirm the end form, thread requirement and available space before selecting an assembly.
Thread Options & Dimensions
Three configurations are listed below. Each row represents one combination of D1, D2, L1, L2 and H. Choose the complete row when requesting a quotation, rather than specifying the thread size alone.
| D1 | D2 | L1 | L2 | H |
|---|---|---|---|---|
| 7/16"-20UNF | 7/16"-20UNF | 108 | 40 | 29 |
| 5/8"-18UNF | 5/8"-18UNF | 110.5 | 56 | 40 |
| 3/4"-16UNF | 3/4"-16UNF | 126 | 50 | 39.5 |
How to Select the Right Assembly
Check both connections. Match D1 and D2 to the mating fittings. The three listed options use matching thread specifications at both ends: 7/16"-20UNF, 5/8"-18UNF or 3/4"-16UNF.
Compare the installation layout. Review the overall tube profile and the L1 and L2 dimensions against your installation space. For a replacement part, send a photo or drawing of the existing assembly so the end arrangement and dimensions can be compared.
Specify the complete requirement. Include the selected table row, required quantity and any equipment-specific connection details. If your requirement differs from the listed options, send the drawing for review.
Ordering & Wholesale Inquiries
For refrigeration parts importers, distributors and equipment sourcing teams, providing the thread specification and complete dimensional requirement helps identify the correct assembly. Please include D1, D2, L1, L2 and H values with your inquiry, together with the quantity and destination.
If your order requires a particular packing arrangement, labeling or supporting product information, include those details in the quotation request. Pricing and packing can then be confirmed for the selected configuration.

Frequently Asked Questions
Which thread sizes are listed?
The range lists 7/16"-20UNF, 5/8"-18UNF and 3/4"-16UNF, with matching D1 and D2 sizes in each row.
What should I send for a replacement inquiry?
Send photos of both connection ends, the thread specifications, a dimensional drawing or measurements, and the quantity required. This allows the listed assembly to be compared with your existing part.
Can I request a quotation for more than one size?
Yes. List the required quantity against each dimensional configuration so each item can be quoted separately.
