Collection: Membrane Housing Pressure Vessels

This comprehensive collection features a wide selection of professional-grade pressure vessel membrane housings designed to accommodate commercial, industrial, and marine reverse osmosis (RO) systems. Engineered to ensure secure containment and optimal fluid dynamics, these universal housings are built to accept standard 2.5-inch and 4.0-inch diameter spiral-wound membrane elements across a variety of lengths, ensuring seamless integration into both new system builds and existing water treatment configurations.

To meet the exact specifications of diverse purification environments, the collection offers vessels in three primary material constructions. For high-pressure seawater desalination and marine watermakers, the Fiberglass Reinforced Plastic (FRP) housings safely operate at continuous-duty pressures up to 1,000 PSI. For standard tap and brackish water applications, "The Original" American-made PVC housings provide a highly durable, cost-effective solution rated for 225 PSI. Additionally, heavy-duty 304 and 316 Stainless Steel housings are available, offering exceptional corrosion resistance and structural integrity for commercial systems operating between 250 and 300 PSI. Designed with secure locking mechanisms—ranging from robust U-pins to heavy-duty retaining clamps—each vessel guarantees a leak-proof seal and long-term reliability.
