2521 1000 PSI FRP Fiberglass Pressure Vessel Housing for 2.5 x 21 inch Membranes

2.5" x 21" American-Made Fiberglass Pressure Vessel (1,000 PSI)

This fiberglass reinforced plastic (FRP) pressure vessel is proudly designed and manufactured in the United States by HCTI (Hydrocomponents & Technologies, Inc.). Built in-house as part of HCTI's own domestically produced vessel line, it houses a single 2.5" x 21" membrane element, giving customers a dependable, American-made vessel backed directly by the company that builds it.

Constructed with a durable, non-corrosive fiberglass housing in natural color (white finish available on request), this vessel features end-entry feed and brine ports standard on every unit. An anodized aluminum retaining clamp locking device makes installation straightforward, while flush-mount anodized aluminum or acetal co-polymer end plugs, backed by stainless steel backing plates, keep fitting installation simple and effortless. FDA-approved ethylene propylene (EPDM) O-rings are standard, with silicone and other compound options available on request.

Rated for 1,000 PSI working pressure, this vessel is built with maximum separation between the permeate port and the feed/concentrate port, allowing the use of larger fittings without crowding. At 24" overall length, with 1/4" NPT ports across feed, brine, and permeate, it's sized for watermaker, desalination, and small-scale RO installations that need a single 2.5" x 21" element housed in a proven, US-manufactured vessel.
