STK Stainless Steel RO Membrane Housing (End Entry / Clamp Type)

Engineered for industrial Reverse Osmosis systems, the STARK End Entry Membrane Housing features a seamless stainless steel body with a heavy-duty Tri-Clamp closure. Designed for 2.5" and 4" standard membranes, it offers superior corrosion resistance (SS304/316L) and a high-pressure rating of 300 PSI. Ideal for food & beverage, pharmaceutical, and commercial water filtration projects.

Professional Grade Stainless Steel Pressure Vessel

The STK End Entry RO Membrane Housing sets the standard for reliability in commercial and industrial water treatment applications. Unlike fiberglass alternatives, our stainless steel housings provide unmatched mechanical strength, UV resistance, and a sanitary finish that meets the strict requirements of the food and pharmaceutical industries.

Why Choose STARK End Entry Housings?

  • Seamless Construction for Safety: We utilize continuous seamless stainless steel tubes to manufacture the housing body. This eliminates longitudinal welds, significantly enhancing pressure handling capabilities and eliminating the risk of seam leakage under high-pressure operation.
  • Sanitary Mirror Finish: Both the interior and exterior surfaces undergo a multi-step mechanical polishing process (Exterior: 400 Mesh). This results in a smooth, mirror-like finish (Ra ≤ 0.8µm) that prevents bacterial adhesion and makes the unit easy to clean and maintain.
  • Quick-Access Clamp Design: The End Entry series features a user-friendly Tri-Clamp closure system. This design allows operators to rapidly open the housing for membrane change-outs without specialized tools, reducing system downtime and maintenance costs.
  • Rigorous Quality Testing: To ensure absolute safety, every single housing undergoes a hydrostatic pressure test at 1.5 times the design pressure before packaging. We guarantee zero leakage and structural integrity.
