1 inch Copper Coupling less Stop Copper x Copper

1 inch Copper Slip Coupling – Precision-Fabricated for Inline Repairs and Extensions

The 1 inch Copper Slip Coupling is designed for use in plumbing systems requiring axial movement to facilitate pipe alignment or to perform repairs where a section must be replaced. Manufactured from high-grade copper, this coupling enables full-length insertion without the need for stop shoulders, ensuring continuous interior wall surfaces for optimal fluid flow.

Fabricated to meet applicable plumbing and mechanical codes, the slip coupling supports both residential and light commercial installations. Its seamless design is ideal for soldered joints where ease of alignment and integrity under temperature and pressure cycling are critical factors.

Performance Features

• ✅ Full-Slip Design – Allows insertion over copper tube ends for inline splicing without dimensional interference.
• ✅ Material Composition – Rolled from UNS C12200 copper tubing to provide excellent corrosion resistance and thermal conductivity.
• ✅ Dimensional Tolerances – Precision-formed to ASTM B88 and ASME B16.22 standards to ensure proper fit and compatibility with Type M, L, or K tubing.
• ✅ Pressure Rating – Suitable for systems operating up to 200 PSI at ambient temperatures, and up to 100 PSI at elevated temperatures when properly soldered.

Applications

Primarily used in potable water distribution, hydronic heating, and DWV systems, this slip coupling is essential for field repairs or layout adjustments where a section of pipe requires replacement. It is particularly useful when space constraints or immobile pipe ends make traditional couplings impractical.

Installation Guidelines

Preparation includes cleaning tube ends with appropriate abrasive cloth and applying lead-free solder in conjunction with approved flux. Ensure uniform heating to promote full solder capillary action across the joint. Do not use for press or flare systems. Verify system compatibility with local code requirements prior to installation.
