1-1/2 inch Copper Coupling with Stop – Wrot Fitting for Sweat Connections
The 1-1/2 inch Copper Coupling with Stop is a wrot copper fitting used for joining two sections of copper tubing in potable water or hydronic systems. It features a center stop to ensure precise tubing alignment during installation. Manufactured to meet applicable standards for solder-type fittings, this coupling supports clean, code-compliant connections in residential and commercial plumbing systems.
Suitable for use with Type K, L, and M hard-drawn copper tubing, the coupling is fabricated from lead-free wrought copper alloy and is listed under NSF/ANSI 61 and 372 for potable water systems. It provides a secure, sweat-joined connection that meets mechanical and hydraulic performance requirements in both vertical and horizontal pipe runs.
Product Specifications
- Nominal Size: 1-1/2 inch
- Connection: Cup (socket) x Cup with integral stop
- Material: Lead-free wrought copper (compliant with ASTM B75/B88)
- Certification: NSF/ANSI 61 & 372 for potable water contact
- Application: Soldered joint for pressure and non-pressure systems
Performance Characteristics
- Stop Feature: Ensures uniform pipe insertion depth and prevents over-penetration during installation.
- Corrosion Resistance: Copper offers natural resistance to scaling and chemical degradation in potable water systems.
- Temperature/Pressure Rating: Suitable for systems up to 400 PSI at 100°F (per ASME B16.22 guidelines).
- Versatility: Applicable in hot/cold water supply lines, hydronic heating systems, and non-potable distribution.
Installation Notes
Prepare pipe ends by cleaning and reaming prior to insertion. Use lead-free solder and approved flux for joining. The integral stop aids in maintaining alignment during heating and cooling cycles. Follow local plumbing code and ASME B31.3/B31.9 requirements for joint preparation, spacing, and support.
Use Case Applications
Installed in copper piping systems for municipal, institutional, and residential buildings. Commonly used in branch extensions, pipe repairs, or when routing changes require in-line connection with position control.
Code Compliance
Conforms to ASME B16.22, MSS SP-104, and UPC/IPC requirements for copper solder fittings in water distribution and mechanical systems.
