Reducer coupling Herz P 7026 01, reducing 26x3 to 16x2 (P702601)

The Herz reducer coupling P 7026 01 is a compact pipe fitting designed to connect a 26x3 pipe to a 16x2 pipe. Manufactured by Herz, this reducing coupling provides a stable mechanical and hydraulic transition between pipes of different outer diameters and wall thicknesses, suitable for plumbing and heating systems where a dimension-matched joint is required.

Advantages

The coupling delivers a reliable, leak-resistant connection when installed according to recommended methods. Its reduction profile enables straightforward adaptation between larger and smaller diameter pipes without the need for additional adapters. The component is made to fit standard pipe dimensions, simplifying inventory and installation on site.

Suitable for

• Domestic and commercial plumbing systems requiring a transition from 26x3 to 16x2 piping
• Heating installations such as radiators, boilers, and underfloor heating manifolds
• Repair or modification work where a secure hydraulic connection between differing pipe sizes is needed

Key specifications

• Reduction: from 26x3 (larger pipe) to 16x2 (smaller pipe)
• Function: mechanical and hydraulic coupling for pipe size transition
• Material compatibility: suitable for common plumbing and heating pipe materials (use matching pipe type for best results)
• Application environment: indoor plumbing and heating systems

How to use

Select pipes with the specified outer diameters and wall thicknesses (26x3 and 16x2). Prepare pipe ends by cutting square, deburring, and cleaning to ensure full contact. Slide the coupling onto the prepared larger pipe or smaller pipe first according to the chosen installation sequence and secure using the appropriate joining method compatible with the coupling design and pipe material (for example compression, press, or soldering if applicable). Follow system pressure ratings and local plumbing codes when tightening and testing the connection.

Usage recommendations

Verify material compatibility and pressure/temperature limits of the complete piping system before installation. Perform a leak test after assembly, and use proper tools and torque settings recommended for the chosen joining method to ensure a lasting, watertight joint.
