Elkhart Products WP0-RING-04 Copper Coupling with Stop

Product Description

The ELKHART PRODUCTS WP0-RING-04 is a WROT copper coupling with stop, designed for sweat-solder connections in copper tubing systems. Sized at 1/4 inch (3/8 inch OD ACR) with a C x C configuration, this fitting accepts standard copper tubing on both ends and uses a built-in stop to ensure consistent seating depth during installation. WROT copper construction provides reliable performance in potable water, hydronic, and refrigeration tubing applications. Licensed plumbers, HVAC technicians, and pipefitters install this type of fitting as part of larger copper piping assemblies where precise tube positioning is required.

This coupling with stop is suited for residential and light commercial copper piping work, including domestic water supply lines, refrigerant line sets, and hydronic heating circuits. The 1/4 inch nominal size targets smaller-diameter runs common in ACR (air conditioning and refrigeration) applications. The integral stop eliminates the need to measure and mark insertion depth, reducing installation time on multi-joint assemblies.

Key Features

• WROT copper construction for consistent material density and solder-joint integrity
• Built-in stop for accurate, repeatable tube seating depth
• C x C solder-type connection compatible with standard sweat-soldering methods
• 1/4 inch nominal size fits 3/8 inch OD ACR tubing
• Compact dimensions support use in tight spaces within mechanical systems

Compatibility

Designed as an OEM-style replacement or new-install fitting for 1/4 inch nominal copper tubing systems using C x C solder-type connections, including ACR applications with 3/8 inch OD tubing.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians following applicable plumbing and mechanical codes, including IPC and IFGC guidelines where relevant. Shut off water supply or depressurize the refrigerant circuit completely before cutting or fitting copper tubing. Clean tubing ends and fitting cups with emery cloth or a pipe cleaning brush, apply flux, and solder using a propane or MAP torch with lead-free solder meeting local code requirements. Allow the joint to cool before restoring pressure.
