Reducing Coupling

Poly Reducing Coupling – Black Polyethylene (PE)

Black Polyethylene Reducing Couplings (sockets) are designed to connect BSP threaded pipes or fittings of different sizes securely. Manufactured from high-quality polypropylene, these fittings are durable, lightweight, and resistant to corrosion, chemicals, and UV exposure—ensuring long-lasting performance for both plumbing and irrigation systems.

Made to AS/NZS 4020 standards, these reducing couplings are suitable for residential, commercial, and irrigation applications. Many brands also hold WaterMark approval, ensuring compliance with Australian plumbing regulations.

Key Features

• Durable Polypropylene Construction – Provides long-lasting strength and reliability.
• Reducing Connection – Connects two BSP threaded pipes or fittings of different sizes.
• Chemical & UV Resistant – Performs well in outdoor and industrial applications.
• BSP Thread Compatibility – Female x Female threads designed for secure connections.
• High Pressure Ratings – Supports up to PN16 depending on size.
• WaterMark Approved (many brands) – Ensures Australian plumbing compliance.
• Easy Installation – Works best with white Teflon thread sealant.
• Versatile Applications – Suitable for plumbing, irrigation, and mains water systems (licensed plumber required).
