Dakota Sourcing 13110 Copper Coupling 1-5/8 Od Roll Stop

Product Description

The DAKOTA SOURCING 13110 is a copper coupling with a roll stop designed for joining copper tubing in plumbing, HVAC, and refrigeration piping systems. The roll stop feature provides a positive seating point that controls insertion depth, ensuring consistent, repeatable joints during soldering or brazing operations. This fitting has a 1-5/8 inch outer diameter and a 1-1/2 inch inner diameter, making it suited for standard 1-1/2 inch nominal copper tube. Licensed plumbers and HVAC-R technicians are the primary installers of this fitting.

This coupling is used in residential and light commercial applications where copper piping is the specified material. Typical install scenarios include domestic water distribution, hydronic heating lines, chilled water piping, and refrigerant line sets where a full-length coupling with a stop is required. The roll stop design distinguishes this fitting from slip couplings, which are used for repair work requiring axial movement of the fitting over cut pipe ends.

Key Features

• Roll stop prevents over-insertion and ensures consistent joint depth
• 1-5/8 inch OD fits standard 1-1/2 inch nominal copper tubing
• Copper construction compatible with soldering and brazing joining methods
• Full-port bore supports unrestricted flow through the coupling

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 1-1/2 inch nominal copper tube systems in plumbing and HVAC piping applications.

Installation Notes

Installation is performed by licensed plumbers or HVAC-R technicians following applicable local plumbing codes and ASTM standards for copper tube and fittings. Shut off and depressurize the water or refrigerant system completely before cutting into any existing line. Clean pipe ends and fitting sockets thoroughly before applying flux and soldering or brazing per the joint method required by the system. Do not use this fitting on gas lines unless the piping material and fitting type are explicitly approved for that service under the applicable code.
