Straight Coupling Herz P 7026 00 (P702600) 26x3 – copper pipe connection fitting

Herz straight coupling P 7026 00 is a 26x3 copper pipe connection fitting designed to join two pipes of the same diameter in a compact, inline configuration. Intended for use in plumbing and heating systems, this coupling enables a continuous run of copper or compatible metal piping where a durable, leak-resistant mechanical join is required. The fitting is suitable for residential and commercial water supply, heating circuits and circulation lines that require a stable, space-saving connection.

Advantages

The straight coupling provides a simple, linear connection that maintains internal flow characteristics and minimizes pressure loss. Manufactured to match standard copper pipe dimensions, the fitting ensures consistent pipe alignment and mechanical strength at the joint. Its compact design reduces the space needed for installation and helps keep visible pipe runs neat. The coupling is suitable for use in systems where a robust metallic connection is preferred over flexible alternatives.

Suitable for

• Joining two 26x3 copper or compatible metal pipes in-line
• Residential and commercial water supply lines
• Heating systems and radiator connections
• Circulation loops in hydronic systems

Key specifications

• Material: copper-compatible metal (suitable for copper pipe connections)
• Connection type: straight, inline coupling for same-diameter pipes
• Nominal pipe size: 26 x 3 mm
• Application: plumbing, heating and circulation systems
• Design: compact inline fitting for minimal space usage

How to use

Prepare pipe ends by cutting square and deburring to ensure full contact with the coupling. Slide the coupling into position so that each pipe end is fully engaged in the fitting. Follow the chosen joining method appropriate for the system and installer practice (for example, soldering, brazing or approved mechanical joining process compatible with the coupling and pipe material). After installation, inspect joints visually and perform pressure testing according to local regulations and project requirements to confirm leak-tightness before placing the system into service.

Usage recommendations

Use the coupling with correctly sized 26x3 copper or compatible metal pipes and follow relevant plumbing and heating codes. Ensure installation is performed by qualified personnel using suitable joining techniques and testing procedures. Avoid using the fitting in systems with incompatible fluids or temperatures beyond the materials' rated limits.
