Herz connection fitting M22×1.5 plastic 16×2 for plumbing systems

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.
