2514 1000 PSI FRP Fiberglass Pressure Vessel Housing for 2.5 x 14 inch Membranes

2.5" x 14" Fiberglass Pressure Vessel (1,000 PSI, Made in USA)

This fiberglass reinforced plastic (FRP) pressure vessel is proudly designed and manufactured in the United States by HCTI (Hydrocomponents & Technologies, Inc.). Built in-house, this vessel is part of HCTI's own domestically produced line, maintaining direct control over the materials, construction, and quality of every unit. Sized to house a single 2.5" x 14" membrane element, it has become a popular choice among DIY watermaker builders, with mentions across online forums, blogs, and video tutorials from the desalination and marine community.

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 for specialized applications.

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 a compact 17" overall length, it's well suited for space-constrained watermaker and small-scale desalination installations where a single 2.5" x 14" element is the right fit.
