4″ Quick Assembly FRP Membrane Housing is a certified, user-friendly component for reverse osmosis systems, designed for easy installation and reliable performance:
Core Performance: Features a working pressure of 300PSI, accommodating 1–2 membrane elements. It passes over 100,000 fatigue tests and 4× burst pressure tests, and is compatible with various complex media environments.
Certifications & Quality: Approved by EU CE, ISO9001 quality management system, and domestic hygiene licenses, ensuring compliance with strict standards.
Design & Customization: Equipped with quick-assembly accessories (clamps, gaskets, etc.) for easy setup. Standard colors include white, blue, and green, with other custom colors available.
Ideal for RO systems requiring fast maintenance and consistent performance, this housing balances convenience, durability, and regulatory compliance.
Product Advantages
In order to make up for the abrasion resistance of FRP, embedded steel rings were added to it. Winder® products will wind the embedded ring in the membrane housing during the winding process, which is integrated with the membrane housing and is not easy to fall off. The size and thickness of the embedded ring is proportional to the pressure of the membrane housing. The larger the pressure of the housing, the steel ring will thicken, so that the membrane housing and the pressure head are more firmly connected. The embedded rings are all made of stainless steel 316L, which is more resistant to corrosion and higher temperatures, and has a long service life.

The inner wall of the membrane housing is as bright as a mirror, which can facilitate the disassembly and assembly of the membrane core; it can ensure that the membrane housing has no leakage problem.
The design of the red plug: the production material is ABS modified raw material, which is more durable; the design of the four corners is more convenient and quick to install.
π-shaped silicone ring: using food street silicone raw materials, this design is double-sealed, double-safe, leak-proof and reliable, and the quality is more stable.
There is a unique ID code on the inner wall of each membrane housing, which is used as an anti-counterfeiting mark and can also make the model of the membrane housing clear at a glance.
