A.Y. McDonald 6133T-1IN 1" CTS Insert Fitting

The A.Y. McDonald 6133T-1IN is a 1" CTS (copper tube size) insert fitting designed for rough-in connections on polyethylene and similar CTS-dimensioned tubing runs found in water service and distribution piping. As an insert-style fitting, it is built to be pushed into the bore of CTS tubing and secured with an appropriate clamp or coupling on the job site, making it a straightforward component for plumbers and underground water service contractors who need a dependable transition point along a CTS pipe run. The 1" trade size (CTS) matches common residential and light commercial water service tubing, and the insert connection method is a widely used approach for joining plastic tubing without solvent welding or threading. A.Y. McDonald has long been a name trade professionals recognize in waterworks and plumbing supply, and the 6133T-1IN carries that same catalog identity forward under model reference 4130-760 / 6133T.

Key Features

  • Trade Size: 1" CTS (copper tube size) insert connection for compatible tubing runs.
  • Insert-Style Connection: Designed to insert directly into CTS tubing bore, a common method for joining plastic water service pipe in rough-in and underground installations.
  • A.Y. McDonald Catalog Identity: Cross-referenced as model 6133T / catalog 4130-760, so contractors reordering by A.Y. McDonald catalog number can match this part with confidence.
  • Rough-In Application: Intended for behind-the-wall or underground water service tubing connections rather than exposed decorative plumbing.
  • Trade Professional Use: Sized and configured for use by plumbing and waterworks contractors performing CTS tubing installations and repairs.

A.Y. McDonald 6133T-1IN – Frequently Asked Questions

1) Will an A.Y. McDonald 6133T fitting work on IPS-sized poly pipe?
No. The 6133T is a CTS insert fitting, dimensioned to copper tube size tubing, and IPS poly pipe has a different bore. Pushing a CTS insert into IPS pipe (or the reverse) gives you a joint that either will not seat or will not hold under clamp pressure. Confirm the print on your tubing says CTS before you order this one.
2) Do I need clamps to install a 6133T insert fitting, or does it come with them?
Clamps are separate. An insert fitting is pushed into the bore of the CTS tubing and then secured with an appropriate clamp or coupling on site, so plan on stainless insert clamps sized for your 3/4 inch or 1 inch CTS tubing as part of the same order. Nothing is solvent welded or threaded at the tubing side.
3) Is the 6133T fitting suitable for underground water service, or just interior rough-in?
Both. A.Y. McDonald lists the 6133T for water service and distribution piping, including underground CTS pipe installations and residential or light commercial rough-in behind the wall. It is a rough-in and buried-service component, not an exposed trim or decorative fitting.
4) I reorder A.Y. McDonald parts by catalog number. What number matches the 6133T?
The 6133T insert fitting is cross-referenced in the A.Y. McDonald catalog as 4130-760, so a purchase order written against either 6133T or 4130-760 lands on the same part. Add the size suffix to pin the trade size: 6133T-3/4 or 6133T-1IN.
5) Why use an insert fitting instead of a compression or solvent-weld connection on poly water service?
Insert fittings are the common approach for joining plastic water service tubing because they need no solvent cement and no threading of the pipe. You push the barb into the tubing bore and clamp it, which makes it practical in a trench or a crawl space where you cannot get a cement joint to cure cleanly. Compression-style connections are the choice where you need a demountable joint at a meter or valve; the 6133T is for the buried or behind-the-wall tubing run itself.
6) Can I use the 6133T to repair a break in an existing 1 inch poly water line?
Yes, that is one of its listed uses. The 1 inch 6133T-1IN goes into the bore of 1 inch CTS tubing and is clamped, which is the standard repair and replacement method on plastic water service tubing. Cut back to clean, round pipe before inserting, and use two clamps per joint if your local practice calls for it.
