Benefits & Applications

This polypropylene threaded cap stops leaks, protects open pipe ends from contamination, and simplifies maintenance by allowing quick removal and reinstallation. Because polypropylene resists many chemicals and moisture, this cap is a cost-effective alternative to metal fittings for corrosive or wet environments.

Common applications include:

• Plumbing and irrigation systems — end-of-line sealing and seasonal winterization.
• Chemical processing and laboratory piping — where chemical resistance is required.
• Water treatment and wastewater systems — non-corrosive sealing solutions.
• Light industrial and manufacturing piping — protection during assembly and storage.

Before installing, verify thread standard (NPT, BSP, or other) and system pressure requirements. Clean mating threads, apply appropriate thread sealant or PTFE tape if required, and hand-tighten. For pressure-critical or high-temperature systems, consult Barr Plastics technical support to confirm suitability.
