## Long description

MKW321 is a 90° elbow for PEX piping systems, model Sigma-LI, designed to connect a 32 mm PEX pipe to a 1" threaded fitting. This metal plumbing connector provides a compact right-angle transition for water distribution and heating installations. The fitting is intended for use where a durable, space-saving elbow is required and is compatible with common PEX installations in residential and light commercial environments.
Advantages
The metal construction offers mechanical strength and long-term durability compared with plastic alternatives. A standardized 90° angle enables reliable redirection of fluid flow in tight spaces while maintaining system integrity. The connector design ensures a secure threaded transition between PEX piping and standard 1" fittings, reducing the need for additional adapters and simplifying installation where a right-angle change of direction is needed.
Suitable for
 PEX water distribution systems in residential buildings
 Heating circuits and radiators requiring a compact elbow
 Connections between 32 mm PEX pipework and 1" threaded valves or devices
 Light commercial plumbing where a metal 90° connector is preferred
Key specifications
 Connection types: 32 mm PEX to 1" threaded fitting
 Angle: 90° elbow
 Material: metal construction suitable for plumbing use
 Application: potable water and heating installations (where compatible with system materials)
 Installation orientation: right-angle transition for compact layouts
How to use
Prepare the 32 mm PEX pipe by cutting it square and deburring the end. Follow the PEX system's recommended method for attaching metal fittings (crimp, clamp, or push-fit) according to the specific Sigma-LI installation practice and tools. Thread the 1" connection into the mating component using appropriate sealing material on the threads where required by the installation code. Ensure all connections are tightened to the manufacturer's torque recommendations and inspect joints for leaks before putting the system into service.
Usage recommendations
Verify material compatibility with the PEX piping, sealing methods, and the intended media (cold/hot potable water or heating fluids). Use appropriate tools for securing PEX to metal fittings and perform pressure testing after installation to confirm leak-free operation. In installations with aggressive water chemistry or where corrosion risk exists, consider system-level measures to protect metal fittings.
