## Summary description

SiGMA-Li MP251 is a polypropylene (PP) MUFA (mechanical cable gland/pipe coupling) with a half-coupling design and nominal size 25x1. Intended for joining or terminating pipes/cables where a threaded 25x1 connection is required. Provides a durable plastic joint for plumbing, conduit or cable management applications in residential and light commercial installations.

## Long description

SiGMA-Li MP251 MUFA with Half-Coupling 25x1 is a polypropylene (PP) mechanical pipe/cable coupling designed for creating a secure threaded connection in plumbing, conduit and cable management systems. The half-coupling design allows joining or terminating pipes and conduits with a 25x1 threaded interface. Made from durable plastic material, this joint is intended for residential and light commercial applications where a corrosion-resistant, lightweight connector is required.
Advantages
The polypropylene construction provides resistance to corrosion, chemicals and moisture while remaining lightweight and easy to handle. The half-coupling threaded design ensures a straightforward installation with a standard 25x1 thread, reducing the need for special tools. Its plastic composition minimizes thermal conduction and eliminates metal-to-metal contact, making it suitable in environments where electrical insulation or reduced heat transfer is desirable.
Suitable for
Joining or terminating plastic pipes with a 25x1 threaded connection
Cable conduit installations in residential buildings
Light commercial plumbing and drainage where a plastic threaded joint is acceptable
Situations requiring a corrosion-resistant, non-conductive connector
Key specifications
Material: Polypropylene (PP)
Type: Half-coupling mechanical joint / MUFA
Nominal size/thread: 25x1 (threaded connection)
Application: Pipe and cable conduit joining or termination
Typical installation environments: Residential and light commercial
How to use
Prepare the mating pipe or conduit by cutting square and deburring the end. Ensure threads on the mating component match the 25x1 specification and are clean of debris. Screw the half-coupling onto the threaded pipe or fitting by hand until snug, then tighten to a secure fit using appropriate tools if necessary, taking care not to over-torque plastic threads. If required for the application, use compatible sealing tape or sealant on the threads to improve leak resistance. Inspect the assembled joint for correct alignment and secure engagement before placing in service.
Usage recommendations
Use the coupling within recommended temperature and mechanical load limits for polypropylene fittings; avoid excessive mechanical stress and exposure to sources of high heat or open flame. For pressurized systems, verify compatibility and suitability of a plastic threaded half-coupling for the specific pressure class and fluid. Store in a dry, shaded location to prevent long-term UV exposure that can degrade plastic materials.
