Ouding Building Launches Patented PPR Three-Way Shower Mixer Eliminating Leakage Risks with Welding Connection

Ouding Building has introduced its patented PPR three-way shower mixer, a revolutionary alternative to traditional copper threaded valves. Engineered with a welding connection system, this innovative mixer permanently eliminates the risk of water leakage in concealed wall installations – a common failure point in conventional threaded designs. Manufactured from high-grade PPR and nylon materials, the product meets ISO 15874‑3 and GB/T 18742‑3 standards, and has already gained market recognition in South America, the Middle East, and Africa. With full OEM support and flexible customization, Ouding Building delivers a durable, safe, and patent-protected solution for modern plumbing systems.

Product Background and Technical Positioning

Conventional shower mixers on the market are predominantly made of copper and rely on threaded connections. Over time, temperature fluctuations, water pressure variations, and material aging can cause thread loosening or seal deterioration, leading to hidden leaks that require costly wall demolition for repair. Leveraging over a decade of experience in PPR piping systems, Ouding Building developed a PPR-based shower mixing valve that uses welding (socket fusion) connection, creating a monolithic joint between the valve body and the pipework. This design physically eliminates the risk of leakage caused by thread failure or O-ring aging, ensuring long-term reliability.

Patent Portfolio and Product Series

To date, Ouding Building has developed a full range of PPR mixing valves, including three‑way, four‑way, five‑way, and six‑way configurations, all of which have been successfully patented. The three‑way model (2 inlets + 1 outlet) is available in DN20 or DN25 sizes, compatible with standard residential and commercial shower systems. Trial orders have been well received by overseas customers, with repeat purchases confirming the product's market acceptance.

Structure and Material Composition

The valve body is made from 100% virgin PPR raw material (R200P or RA140E, or specified alternatives) and meets ISO 15874‑3 and GB/T 18742‑3 standards. Body colours include green, dark green, grey, white, or custom shades. The handle can be manufactured in zinc alloy or ABS, while the cover plate comes in square or round shapes, available in 304 stainless steel or ABS. The ceramic cartridge (Φ40mm) can be sourced from domestic or imported suppliers, or designated by the customer.
