## Summary description

SiGMA-Li MP2534 is a connector mufa with a half-union (semi-coupling) designed for joining pipes or fittings with dimensions 25x3/4". It provides a mechanical connection between a 25 mm pipe and a 3/4" threaded element. Suitable for plumbing and heating installations where a transition between metric and BSP/imperial thread sizes is required.

## Long description

SiGMA-Li MP2534 mufa with half-union 25x3/4" is a connector fitting designed to join a 25 mm pipe to a 3/4" threaded element. It provides a mechanical transition between metric pipe systems and BSP/imperial threaded components, allowing secure connection in plumbing and heating installations. The fitting is intended for use where a reliable thread-to-pipe interface is required without altering the existing piping layout.
Advantages
The connector creates a stable mechanical connection between a 25 mm pipe and a 3/4" threaded fitting, minimizing the need for additional adaptors. Its half-union design facilitates installation and disassembly by allowing the threaded element to be separated from the pipe without rotating the entire piping. The fitting supports straightforward alignment and reduces the risk of leaks when properly installed with appropriate sealing materials.
Suitable for
Plumbing systems requiring a transition from 25 mm pipe to 3/4" threaded components
Heating installations and radiators that use mixed metric and imperial connections
Repair or retrofit work where replacing entire piping is impractical
Piping connections in residential and light commercial applications
Key specifications
Connection types: 25 mm pipe interface and 3/4" threaded interface
Design: half-union (semi-coupling) for separable threaded connection
Application: mechanical transition between metric pipe and BSP/imperial thread
Typical installation environment: plumbing and heating systems
How to use
Prepare the pipe end by cutting it square and deburring to ensure a flush fit. Assemble the fitting onto the 25 mm pipe according to the manufacturer's assembly method for the pipe material (e.g., compression, push-fit, or soldered joint as appropriate). Apply appropriate thread sealant (PTFE tape or liquid sealant) to the 3/4" threaded element, then engage the half-union and tighten to the recommended torque for the materials involved. Verify alignment and check for leaks under pressure following installation.
Usage recommendations
Use compatible sealing materials for the threaded connection and follow local plumbing codes. Ensure the fitting is used within the pressure and temperature limits of the connected system and avoid excessive torque during assembly to prevent damage to threads or the union. Periodically inspect the joint for signs of leakage or corrosion.
