## Summary description

VIEGA transitional coupling FKM 22 x 3/4" (MPN 628895) is a plumbing connector designed to join a 22 mm pipe to a 3/4" threaded fitting. Constructed with FKM sealing material, it provides chemical and temperature-resistant sealing for installation in potable and technical water systems. Suitable for household and commercial plumbing repairs and retrofits where a reliable transition between metric pipe and imperial thread is required.

## Long description

VIEGA transitional coupling FKM 22 x 3/4" is a plumbing connector engineered to join a 22 mm pipe to a 3/4" threaded fitting. The fitting uses an FKM (fluoroelastomer) sealing element that offers resistance to a wide range of chemicals and elevated temperatures, making it suitable for potable and technical water systems. The connector provides a compact transition between metric pipework and imperial threaded components in repair, maintenance and retrofit situations.
Advantages
The FKM sealing material ensures long-term resistance to aggressive media and thermal stress, helping to maintain leak-tight connections under varying conditions. The coupling’s design enables a secure mechanical connection between a 22 mm tube and a 3/4" threaded fitting without additional adapters. Its compact form factor simplifies installation in confined spaces and reduces the number of separate parts needed for a reliable transition.
Suitable for
Joining 22 mm copper, plastic or composite pipes to 3/4" threaded valves or fixtures
Household plumbing repairs and replacements
Commercial water installations and technical systems where mixed metric/imperial connections are required
Retrofit projects converting metric pipework to imperial-threaded equipment
Key specifications
Connection: 22 mm tube end to 3/4" male/female threaded fitting
Sealing material: FKM (fluoroelastomer) for chemical and temperature resistance
Application: potable water and technical water systems
Design: compact transitional coupling for metric-to-imperial connection
How to use
Prepare the 22 mm pipe by cutting squarely and removing burrs, then insert the pipe into the coupling according to standard installation practice for the chosen pipe material. Thread the 3/4" fitting into the coupling and tighten to the torque recommended for the mating thread to ensure proper engagement without overloading the seal. Verify alignment and inspect the connection for leaks after pressurizing the system.
Usage recommendations
Use the coupling within the temperature and pressure ranges applicable to FKM seals and the connected piping system. Avoid exposure to media outside the chemical compatibility of FKM. Ensure threads are clean and undamaged before assembly and perform a pressure test after installation to confirm leak-tight performance.
