Reducer coupling Detal-met MR25X20, 25 mm to 20 mm pipe fitting

Detal-met MR25X20 reducer coupling is a pipe fitting engineered to connect a 25 mm diameter pipe to a 20 mm diameter pipe. Designed for plumbing and heating systems, this reducer provides a reliable and compact solution for transitions between pipe sizes in domestic and light commercial installations where downscaling of piping is required. The coupling is suitable for use with compatible materials and standard pipe profiles, offering a straightforward mechanical connection for fluid or gas flows.

Advantages

The reducer coupling delivers a compact and space-saving connection that simplifies the transition from larger to smaller pipework. Its construction ensures a consistent internal profile to maintain flow characteristics and reduce turbulence at the junction. Installation requires minimal tools and permits straightforward integration with existing piping lines, reducing labor time. The fitting is suitable for repeated installations and replacements in maintenance operations.

Suitable for

• Connecting a 25 mm pipe to a 20 mm pipe in plumbing systems
• Downscaling pipework in residential heating installations
• Service and maintenance tasks requiring a size transition
• Light commercial piping where compatible materials and diameters are used

Key specifications

• Connection sizes: 25 mm to 20 mm
• Function: reducer coupling for fluid or gas transitions
• Typical applications: plumbing and heating systems
• Form factor: compact inline reducer

How to use

Verify that both pipes are clean, free of debris and compatible with the coupling material. Prepare each pipe end according to the piping system's standard practice (deburring, cleaning, and applying any required sealant or adhesive if specified by the pipe system). Align the 25 mm pipe and the 20 mm pipe with the coupling and insert each end fully to ensure correct seating. Secure the connection following the installation method appropriate to the pipe material and local regulations. Perform a pressure or leak test as required by the system to confirm a tight joint before commissioning.

Usage recommendations

Use the reducer coupling only with compatible pipe materials and profiles. Check manufacturer guidelines for temperature and pressure limits of the piping system and perform leak testing after installation. For permanent or high-pressure applications, follow industry-standard joining methods and local codes to ensure system integrity.
