3/4" Copper Cap – Built for Termination Integrity in Professional Plumbing Systems

The 3/4" Copper Cap is engineered for terminating copper tube lines in water distribution and HVAC systems. Constructed from high-grade copper material, this fitting is suitable for sweat-solder applications where long-term seal integrity is essential. Its uniform wall thickness and smooth interior profile support precision joining and help ensure system reliability in pressurized environments.

Performance Highlights

Designed for use in systems requiring NSF 61-G certified components, this cap is lead-free and corrosion-resistant, offering excellent durability for both hot and cold water applications. The cap's closed-end design provides a permanent or temporary seal and is often used in rough-in plumbing phases for future connections or testing purposes.

• ✅ Uniform Dimensions Manufactured to ANSI/ASME standards for Type L and Type M copper tubing.
• ✅ High Copper Content Supports corrosion resistance and long service life, especially in potable systems.
• ✅ Sweat Connection Compatible with standard solder fittings and torch techniques for a clean finish.
• ✅ Versatile Installation Suitable for both new construction and maintenance shut-off points in sealed systems.
• ✅ Code-Compliant Fabricated from lead-free materials in compliance with U.S. Safe Drinking Water Act requirements.

Typical Applications

This copper cap is commonly used in commercial and residential potable water systems, as well as hydronic heating loops and mechanical room terminations. It is ideal for capping unused stub-outs or closing off pipe ends where future extension may be needed.

Industry Insight

Permanent caps are frequently installed during pressure testing phases to isolate sections of piping. This facilitates system integrity checks and reduces installation downtime.

Choosing copper caps that adhere to ASTM B88 standards ensures consistent performance, especially under fluctuating temperature and pressure conditions. Make the professional choice with a fitting designed to meet the demands of today’s plumbing environments.
