Connector (Śrubunek) Detal-met SRGW20X1/2 with female thread, PP, 20x1/2"

Detal-met Śrubunek SRGW20X1/2 is a polypropylene (PP) connector designed to join a 20 mm plastic pipe to a 1/2" internal (female) threaded fitting. The component provides a durable, lightweight transition between plain-ended plastic or metal pipes and female threaded valves, fixtures or adapters. Its chemical resistance and corrosion-free material make it suitable for water supply, irrigation and low-temperature heating circuits where a reliable female threaded connection is needed.

Advantages

The PP construction ensures resistance to many common chemicals and prevents corrosion, while keeping the connector lightweight and easy to handle. The female threaded end provides a secure mechanical interface with standard 1/2" threaded fittings, simplifying installation and replacement of valves and fixtures. The connector’s smooth internal surfaces support steady flow and reduced build-up, and the component is suitable for systems where non-metallic connections are preferred.

Suitable for

• Domestic water supply and plumbing repairs
• Irrigation systems and garden watering setups
• Low-temperature heating circuits and distribution manifolds
• Connections to valves, taps and threaded appliances requiring a 1/2" female thread

Key specifications

• Material: polypropylene (PP)
• Pipe connection diameter: 20 mm (socket for plain pipe end)
• Thread type: internal (female) 1/2"
• Suitable media: water and common non-aggressive fluids
• Construction: corrosion-resistant, non-metallic

How to use

Prepare the 20 mm pipe end by cutting square and deburring. Insert the pipe into the plain 20 mm socket until it seats fully; secure the joint according to the piping system’s guidelines (e.g., solvent welding, mechanical clamp, or push-fit method as applicable to the pipe type). Screw the 1/2" male threaded fitting into the connector’s female thread, using suitable sealing (thread tape or thread sealant) to prevent leaks. Tighten to a practical torque to ensure a leak-free joint without over-stressing the plastic threads.

Usage recommendations

Use this polypropylene connector in applications within the temperature and pressure limits of PP materials; avoid exposure to concentrated solvents or high-temperature fluids. When connecting to metal threads, ensure compatible sealing materials and avoid overtightening to preserve thread integrity.
