A.Y. McDonald 5182-001 1" No-Lead CTS Compression Service Coupling

The A.Y. McDonald 5182-001 is a 1" CTS compression service coupling designed for joining underground water service lines behind the wall or below grade, where a dependable, code-oriented connection matters more than appearance. Sized to CTS (copper tube size) dimensions, this coupling accepts 1" CTS tubing on each end via a compression connection, making it a straightforward choice for plumbers and utility contractors repairing or extending water service runs. As a no-lead (LF) fitting, it is intended for potable water service applications where lead-free materials are specified. The compression-style joint allows for field assembly without soldering or solvent welding, which speeds up installation in trenches and tight access points typical of service line work.

Key Features

  • Trade Size: 1" CTS on both ends, matched to standard copper tube size service tubing for straight-line repairs and extensions.
  • Compression Connection: CTS compression ends allow field installation onto service tubing without soldering, sweating, or solvent welding.
  • No-Lead (LF) Construction: Manufactured to no-lead specifications for use in potable water service applications.
  • Straight Coupling Configuration: Joins two lengths of 1" CTS tubing in a straight run, useful for splicing or extending existing service lines.
  • Model Reference: Identified by A.Y. McDonald's internal reference 74758Q for cross-reference and reorder purposes.

A.Y. McDonald 5182-001 – Frequently Asked Questions

1) Will the A.Y. McDonald 5182 coupling join copper service tubing without soldering?
Yes. The 5182 is a compression-end coupling, so both ends clamp onto CTS tubing in the field with no soldering, sweating, or solvent welding. That is the main reason it gets used in trenches and tight access points where a torch is impractical.
2) What sizes does the A.Y. McDonald 5182 service coupling come in?
Two sizes: 1 inch CTS, ordered as 5182-001, and 2 inch, ordered as 5182-079. Both are straight couplings joining two lengths of tubing of the same size.
3) Is the 5182 coupling lead free for potable water service?
The 5182 is a no-lead (LF) fitting, made to no-lead specifications for potable water service lines. That is what makes it acceptable where lead-free materials are called out on a water service repair or extension.
4) Does the 5182 coupling fit CTS tubing or IPS pipe?
CTS. The 5182 is sized to copper tube size dimensions and takes CTS tubing on each end. IPS-dimensioned pipe is a different outside diameter, so it will not seal correctly in these compression ends, and you need an IPS-sized fitting or a CTS-to-IPS transition instead.
5) Can I use the A.Y. McDonald 5182 to splice a broken underground water service line?
That is what it is built for. It joins two lengths of CTS tubing in a straight run, so it works for splicing a cut or damaged section and for extending an existing service run below grade or behind the wall. Both ends assemble in the trench by compression.
6) Is A.Y. McDonald part 74758Q the same as the 5182-001 coupling?
Yes, 74758Q is A.Y. McDonald's internal reference for the 1 inch coupling that orders as 5182-001. Use 5182-001 when reordering; 74758Q is useful for cross-referencing an older quote or parts list.
