The STARK 8040 stainless steel RO membrane housing is designed to meet the rigorous demands of high-pressure industrial water treatment environments. Precision-engineered from corrosion-resistant 304 or 316L stainless steel, the housing ensures long-term durability, leak-free operation, and structural integrity under challenging conditions such as seawater desalination, high-TDS brine filtration, and boiler feedwater purification.
Its interior surface is mirror-polished to reduce friction, prevent scale formation, and minimize biofilm development—ensuring better flow distribution and membrane protection over time. The external body is finished with a brushed anti-oxidation layer, making it suitable for both indoor and outdoor installation without compromising on aesthetics or longevity.
STARK membrane housings are capable of withstanding pressures up to 600 psi, depending on configuration, and are rigorously pressure-tested to industry standards. Each vessel is equipped with high-strength end closures, multi-seal locking systems, and industrial-grade ports (customizable for side or end entry), making it compatible with nearly all standard 8040 RO membrane elements.
Unlike plastic or FRP alternatives, our stainless steel membrane housings offer superior mechanical strength, thermal stability, and resistance to aggressive cleaning chemicals—ideal for industries with frequent CIP (Clean-In-Place) protocols or long operational cycles. The vessel design allows for vertical or horizontal mounting, and supports 1 to 6 membrane elements in series, helping customers maximize system throughput without expanding footprint.
In addition to standard models, STARK offers full customization services. We can manufacture multi-stage housings with tailored flange positions, inlet/outlet angles, anti-vibration brackets, and custom thicknesses to meet specific project demands. All products undergo 100% hydrostatic testing and visual inspection before delivery, and are shipped with technical documentation and optional OEM branding for integrators or engineering clients.
Whether you're upgrading an aging membrane system or designing a new high-efficiency RO plant, STARK stainless steel membrane housings deliver unmatched performance, safety, and peace of mind for industrial water professionals.

STARK’s 8040 RO membrane housing is engineered to serve a wide range of industrial water treatment projects where high-pressure reliability, corrosion resistance, and ease of integration are mission-critical. Whether you operate in harsh coastal environments or need dependable vessels for continuous 24/7 operation, our housings offer flexible solutions trusted across industries.
The STARK 8040 membrane housing is constructed using industrial-grade stainless steel, providing exceptional mechanical strength and resistance to pressure, corrosion, and temperature fluctuations. This durability ensures that the housing maintains its structural integrity even under constant high-pressure operation or harsh chemical cleaning cycles.
Unlike FRP or plastic alternatives, stainless steel vessels offer superior stability, longer lifespan, and reduced risk of cracking or deformation. Each unit is hydro-tested at 1.5× its rated pressure to verify safe performance under real-world conditions. With a design lifespan of over 5 years under standard operation, the STARK housing significantly reduces downtime and replacement costs for industrial water systems.
STARK membrane vessels are engineered with modularity in mind. Each housing supports 1 to 6 membrane elements in a single linear structure, making it easy to expand system capacity without reconfiguring plant layout. Both side-port and end-port options are available to accommodate space constraints and plumbing preferences.
For engineering teams or OEM integrators, we offer complete customization services—from adjusting inlet/outlet flange positions to selecting custom wall thickness, support brackets, or port angles. Whether you're designing a compact skid-mounted system or a large-scale municipal RO line, our engineers will help deliver a housing solution that fits perfectly into your workflow and spec sheet.
