2 inch Copper Cap – Built for End-of-Line Integrity in Pressurized Systems

The 2 inch Copper Cap is designed for terminating copper tube lines in potable water and hydronic heating systems. Constructed from lead-free wrought copper, this fitting delivers a secure, permanent seal when properly soldered, making it suitable for high-pressure applications and long-term reliability.

Advantages of the 2 inch Copper Cap

• ✅ Wrought Copper Construction – Formed from high-integrity copper for improved resistance to pressure cycling and mechanical stress.
• ✅ Lead-Free Compliance – Fully compliant with NSF/ANSI 61 and 372 standards for potable water use in accordance with national plumbing codes.
• ✅ Closed-End Solution – Ideal for dead-end pipe terminations or testing closed piping sections during pressure tests.
• ✅ Sweat Connection – Designed for soldered installations using standard ASTM B88 copper tubing.
• ✅ Corrosion Resistance – Suitable for use in corrosive environments, including heating loop systems and exposed mechanical rooms.

Product Specifications

Installation Guidance

Installation requires proper surface preparation and soldering technique in accordance with ASTM B828. For pressure applications, ensure uniform heating and full capillary penetration using approved solder and flux. Recommended for use by trained professionals familiar with copper system assembly to ensure full code compliance and pressure integrity.

Common Applications

The 2 inch Copper Cap is typically used in:

• ● Domestic water distribution system terminations
• ● Hydronic heating system loop closures
• ● Pressure-testing isolation points
• ● Line stubs for future expansion or rerouting

Code Note

All fittings installed in potable systems must conform to local code requirements and be verified lead-free as required under the Safe Drinking Water Act (SDWA).

For contractors requiring long-term sealing performance and regulatory compliance, the 2 inch Copper Cap offers precision fit and field-proven durability. Specify with confidence and install with the assurance of system integrity.
