## Long description

Herz connection fitting M22×1.5 plastic 16×2 is a threaded adapter designed for plumbing and heating installations using 16×2 mm plastic pipes. The fitting provides a secure M22×1.5 threaded interface to connect valves, hoses or other components with matching threads. Made of durable plastic, the component is intended to simplify assembly and ensure leak-resistant mechanical connection points in water and heating circuits.
Advantages
The plastic construction offers corrosion resistance and a lightweight alternative to metal fittings while maintaining adequate strength for typical residential and commercial applications. The M22×1.5 thread is a common standard, allowing compatibility with a wide range of valves and accessories. Designed for 16×2 mm pipe dimensions, the fitting ensures a snug fit and straightforward installation, reducing the need for additional adaptors when working with standard plastic piping systems.
Suitable for
Connecting radiators, valves and hoses in central heating systems
Water supply pipe connections in residential and commercial buildings
Repair or replacement of existing M22×1.5 threaded joints
Plumbing installations using 16×2 mm plastic pipes
Key specifications
Thread type: M22×1.5
Pipe compatibility: 16×2 mm plastic pipe
Material: plastic
Application: water and heating circuits
How to use
Prepare the 16×2 mm pipe by cutting squarely and deburring the end. Slide the fitting onto the pipe according to the pipe system's joining method (push-fit, adhesive, or mechanical as applicable for the system) and engage the M22×1.5 threaded connection with the mating component. Tighten the thread to the manufacturer-recommended torque for plastic fittings or hand-tighten and secure with an appropriate tool, taking care not to overtighten and damage the plastic thread. Pressure-test the assembled connection according to local plumbing standards before placing the system back into service.
Usage recommendations
Use compatible sealing materials where required and follow system-specific installation instructions. Avoid excessive torque when tightening the M22×1.5 thread to prevent deformation. For long-term installations, verify chemical compatibility between conveyed fluids and the plastic material.
