Compression Coupling WAVIN TIGRIS M1 with Internal Thread 20 mm 3/4" PN10 (3243170262)

WAVIN TIGRIS M1 compression coupling with internal thread for 20 mm pipe and 3/4" female threaded connection, PN10. This fitting is intended for press-fit installation on compatible plastic and multilayer pipes and provides a sealed transition from a press system to a female threaded component. The coupling is designed for use in potable water, heating and general utility installations where a compact press-to-thread connection is required.

Advantages

The compression coupling offers a secure press connection combined with an integrated internal thread for easy attachment of threaded components. Designed for PN10 pressure rating, it ensures mechanical strength and leak-tight performance when installed according to manufacturer guidelines. The compact form factor allows installation in confined spaces and reduces the need for additional adapters when connecting press pipe systems to female-threaded valves or fittings.

Suitable for

• Connecting 20 mm plastic or multilayer press pipe to a 3/4" female threaded fitting
• Potable cold and hot water distribution systems
• Residential and light commercial heating circuits and branches
• Service lines and utility connections requiring a press-to-thread transition

Key specifications

• Nominal pipe size: 20 mm
• Thread size: 3/4" internal (female)
• Pressure rating: PN10
• Connection type: press-fit to pipe with integrated female thread
• Compatible with plastic and multilayer press pipe systems
• Compact design suitable for confined installation spaces

How to use

Prepare the pipe end by cutting square and deburring to ensure a clean contact surface. Insert the pipe into the coupling until it reaches the defined stop. Perform the press operation using a compatible press tool and jaw specified for WAVIN TIGRIS M1 fittings, verifying that the press collar is fully closed. After pressing, connect the female-threaded component by hand and tighten to the required torque using appropriate tools, following the threaded component manufacturer’s instructions. Inspect the joint visually and conduct a pressure test in accordance with applicable standards before putting the system into service.

Usage recommendations

Use only approved press tools and jaws for WAVIN TIGRIS M1 fittings, and follow installation instructions and local regulations. Ensure pipe compatibility and perform a pressure test after installation. Avoid exposure to incompatible fluids and protect the fitting from mechanical damage during assembly.
