## Summary description

WAVIN Tigris M1 coupling with internal thread, 25 mm (3/4") diameter, PN10 pressure rating. Designed for joining plastic pipe systems with a threaded connection, it provides a secure seal and straightforward installation. Suitable for potable water, heating or drainage applications where PN10 rating and 25 mm pipe size are required.

## Long description

WAVIN coupling with internal thread Tigris M1 25 mm (3/4") PN10 is a plastic pipe fitting designed to join 25 mm (3/4") pipes using a female threaded connection. The coupling is intended for use in systems where a PN10 pressure rating is sufficient and where a secure threaded joint is required. It is compatible with Tigris M1 systems and other plastic piping that match the specified diameter and thread form, providing a sealed transition between plain pipe ends and threaded components.
Advantages
The coupling offers a reliable mechanical connection with built-in sealing properties suitable for potable water, heating and certain drainage applications. Its PN10 pressure rating meets common domestic and light commercial requirements. The plastic construction resists corrosion and scale formation, reducing maintenance compared with metal fittings. Installation is straightforward and does not require specialized tools beyond those typically used for threaded plumbing connections.
Suitable for
Connecting 25 mm (3/4") plastic pipes to threaded valves or fixtures
Potable water distribution where PN10 rating is acceptable
Low-pressure heating circuits and radiator connections
Repair or modification of existing plastic piping systems
Key specifications
Nominal diameter: 25 mm (3/4")
Connection type: internal (female) thread
Pressure rating: PN10
Material: plastic suitable for potable water use
Compatibility: designed for Tigris M1 piping systems and compatible 25 mm plastic pipes
How to use
Prepare the pipe ends by cutting square and deburring to ensure full engagement of the coupling. Threaded components should be wrapped with appropriate thread sealant tape or sealant compatible with plastic fittings if required by local practice. Hand-tighten the coupling onto the mating thread, then complete the final tightening with an appropriate wrench, taking care not to over-tighten the plastic thread. After installation, pressurize the system and inspect the joint for leaks; retighten slightly if permitted and necessary.
Usage recommendations
Use the coupling within the specified PN10 pressure limit and temperature range for the pipe material. Avoid excessive torque during installation to prevent thread damage. For systems supplying drinking water, follow local regulations for potable water fittings and use compatible thread sealants. Regularly inspect accessible joints for signs of wear or leakage, especially after system modifications or pressure testing.
