Detal-met Półśrubunek PP 20 mm 3/4" PS20X3/4 plumbing fitting

Detal-met Półśrubunek PP 20 mm 3/4" PS20X3/4 is a polypropylene half-union fitting designed to join 20 mm plastic pipes with 3/4" threaded components. The fitting provides a lightweight, corrosion-resistant transition between socket-type pipe connections and standard threaded plumbing fixtures. It is suitable for cold and warm water distribution systems, repair work and installations where a reliable threaded-to-socket coupling is needed.

Advantages

The polypropylene construction ensures chemical and corrosion resistance, low weight and dimensional stability. The half-union design allows for a secure threaded connection while simplifying assembly and disassembly for maintenance. Smooth interior surfaces reduce flow resistance and the material resists scale and typical household water contaminants, increasing service life in normal plumbing conditions.

Suitable for

• Joining 20 mm plastic distribution pipes to 3/4" threaded valves and fixtures
• Domestic cold and warm water plumbing systems
• Repair or replacement of small sections of piping
• Connections where periodic disassembly for maintenance is required

Key specifications

• Material: polypropylene (PP)
• Connection types: socket for 20 mm pipe to 3/4" male/female threaded connection
• Application temperature: suitable for cold and warm water (typical household ranges)
• Resistance: corrosion and chemical resistance typical of PP
• Weight: lightweight for ease of handling and installation

How to use

Prepare the 20 mm pipe by cutting it square and deburring the end to ensure a smooth fit into the socket. If solvent welding or adhesive is required for the socket joint, follow the adhesive manufacturer's instructions for surface cleaning, primer application and curing time. Screw the threaded half of the union to the corresponding 3/4" threaded component and hand-tighten; use appropriate tools to finish tightening without over-torquing to avoid damaging the polypropylene threads. After assembly, inspect the joint and perform a pressure or leak test in line with local plumbing codes.

Usage recommendations

Use the fitting within recommended temperature and pressure ranges for polypropylene materials, avoid exposure to open flames and strong solvents, and follow local plumbing standards for installation and testing. For long-term reliability, ensure threads are clean and use compatible sealing tape or sealant on metal-to-plastic threaded interfaces as appropriate.
