A.Y. McDonald 5141-142 1" CTS x CTS x CTS Compression Tee

The A.Y. McDonald 5141-142 is a 1" compression tee configured CTS x CTS x CTS, identified in the manufacturer catalog as AYM 74760-22. This three-way compression fitting is designed to branch or tee off copper tubing size (CTS) piping runs in water service and distribution applications, giving installers a reliable, no-solder connection point for tapping a new line off an existing 1" CTS main or branch line. Each of the three ports on the 5141-142 is sized to CTS dimensions, allowing consistent, straightforward assembly across all three connection points without mixing thread or IPS sizing. As a compression-style fitting, the 5141-142 is intended for applications where a mechanical, gasketed seal is preferred over soldered or threaded joints, simplifying installation and future serviceability in underground or below-grade water service work. Contractors and utility crews rely on documented, spec-sheet-backed fittings like this one to ensure a proper mechanical seal without the need for torches, flux, or solder on the jobsite, which is especially valuable when working in wet trenches or confined below-grade vaults where open flame is impractical or prohibited.

Key Features

  • Trade Size: 1" CTS connections on all three ports for consistent sizing across the fitting.
  • Configuration: CTS x CTS x CTS tee design allows branching off a main line without changing pipe sizing.
  • Connection Type: Compression fitting design provides a mechanical, no-solder joint for faster field installation.
  • Manufacturer Reference: Cataloged under AYM 74760-22, matching A.Y. McDonald's documented specification sheet for this part.
  • Tee Configuration: Three-way body enables a branch connection point in water service piping runs.
  • Serviceability: Mechanical compression joints allow for easier future disassembly compared to soldered connections.

A.Y. McDonald 5140-119 – Frequently Asked Questions

1) What sizes does the A.Y. McDonald CTS compression tee come in?
Two sizes: a 3/4 inch tee, part number 5140-119, and a 1 inch tee, part number 5141-142. Both are compression tees for copper tubing size (CTS) piping.
2) Is the A.Y. McDonald 5141-142 tee the same size on all three ports?
Yes. The 5141-142 is configured CTS x CTS x CTS at 1 inch, so all three ports take the same 1 inch CTS tubing. You branch off without any bushing or size change at the fitting.
3) Do I need to solder this A.Y. McDonald tee, or does it seal mechanically?
No soldering. It is a compression fitting with a mechanical, gasketed seal, so no torch, flux or solder is needed. That matters in wet trenches and below-grade vaults where open flame is impractical or not permitted.
4) Is this compression tee suitable for buried water service lines?
Yes, that is its intended use. The A.Y. McDonald compression tee is made for water service and distribution work, including underground and below-grade branching off a CTS main, and for municipal and residential utility installations.
5) What part number do I quote to replace an existing A.Y. McDonald 1 inch compression tee?
For a 1 inch CTS x CTS x CTS compression tee, order 5141-142, which A.Y. McDonald also catalogs as AYM 74760-22. If the existing run is 3/4 inch CTS, the matching tee is 5140-119.
6) Can I take this tee apart later if I have to service the line?
Compression joints unbolt and come apart, which a soldered joint does not. That makes the 5140-119 and 5141-142 tees a practical choice where a branch may need to be reworked, extended, or repaired later.
