## Long description

Herz straight coupling P 7026 22 with 26x3 outer diameter and Rp3/4 internal thread is a compact plumbing fitting designed to join a 26x3 mm pipe to a component with Rp3/4 female thread. Made for heating, water supply and sanitary systems, the coupling provides a stable mechanical connection that keeps flow paths aligned and suitable for installations where a pipe-tothread transition is required.
Advantages
The straight coupling offers a straightforward, space-efficient connection between a 26x3 pipe and Rp3/4 threaded fittings, reducing the need for complex adapters. Its construction ensures reliable mechanical stability and alignment for pressurized water and heating circuits. The coupling's dimensions make it compatible with standard 26x3 tubing and common Rp3/4 threaded components used in residential and commercial plumbing.
Suitable for
 Connecting 26x3 mm copper or compatible metal pipe to Rp3/4 threaded valves and fittings
 Heating system installations where pipe-to-thread transitions are required
 Water supply and sanitary installations with Rp3/4 threaded components
 Replacement or retrofit work in compact mechanical assemblies
Key specifications
 Connection A: outer diameter 26x3 mm (pipe connection)
 Connection B: internal female thread Rp3/4
 Type: straight coupling for pipe-to-thread transition
 Application: heating, water supply and sanitary systems
 Design: compact inline mechanical coupling
How to use
Prepare the 26x3 pipe end by cutting square and deburring the inner and outer edges. Slide the pipe into the coupling until it seats firmly against the internal stop. Thread the Rp3/4 female side onto the matching male threaded component using appropriate sealing method for the system (for example, PTFE tape or approved jointing compound) where required. Tighten to the torque recommended for the mating components to avoid over‑stress; ensure alignment and check for leaks after pressurisation.
Usage recommendations
Use the coupling only with compatible 26x3 tubing and Rp3/4 threaded fittings. Verify material compatibility with the system fluid and operating temperature/pressure. During installation, follow local plumbing codes and manufacturer's guidelines for thread sealing and torque values. After installation, perform a pressure test and visually inspect joints for any signs of leakage.
