Pipe fitting coupling Detal-met PP Mufa GZ 40 x 1" — threaded 40 mm to 1 inch

Detal-met PP Mufa GZ 40 x 1" is a polypropylene (PP) pipe coupling that converts a 40 mm smooth pipe connection to a 1" threaded fitting. Intended for fluid and water systems, this coupling delivers the chemical resistance and corrosion-free performance characteristic of PP materials and is suitable for both new installations and repair work. The component enables a secure transition between plastic piping and threaded fixtures while maintaining leak-tight joints when installed correctly.

Advantages

The coupling offers durable corrosion resistance and chemical stability typical of polypropylene, ensuring long service life in potable and non-potable water systems. Its design facilitates a reliable mechanical connection between a 40 mm pipe and a 1" threaded component, reducing the need for additional adaptors. Lightweight and easy to handle, the fitting resists scale buildup and many common chemicals encountered in domestic and light commercial plumbing.

Suitable for

• Residential cold and hot water distribution (compatible with PP systems within recommended temperature limits)
• Plumbing repairs and retrofit work where conversion to a 1" threaded fitting is required
• Irrigation and garden water lines
• Non-corrosive chemical transfer systems compatible with polypropylene

Key specifications

• Material: polypropylene (PP)
• Connection type: smooth 40 mm pipe to external/internal 1" thread conversion
• Typical applications: water and fluid systems, plumbing junctions and repairs
• Corrosion resistance: inherent to PP material
• Installation: socket/joint for 40 mm pipe with threaded interface for 1" fitting

How to use

Prepare the 40 mm pipe end by cutting square and deburring to ensure a clean, even face. Insert the pipe into the coupling socket to the recommended insertion depth and secure according to the system method (socket welding, adhesive or mechanical depending on system compatibility). Apply appropriate thread sealant or tape to the 1" threaded fitting before engaging the coupling thread to achieve a leak-tight connection. Follow applicable local plumbing codes and the pipe manufacturer's installation guidelines for temperature and pressure limits.

Usage recommendations

Use the coupling within the temperature and pressure ranges recommended for polypropylene systems; avoid exposure to service conditions involving incompatible solvents or temperatures above PP limits. Verify thread direction and hand-tighten before final torqueing; inspect joints for leaks after commissioning and periodically during service.
