PureT (SSMH-4040-12) 4" x 40" x 1/2" 304 Stainless Steel Membrane Housing, With Plastic End Cap
4" x 40" Stainless Steel Membrane Housing
The PureT SSMH-4040-12 is built for operators who need corrosion-resistant housing that handles standard 4" x 40" RO membranes in commercial applications. The 304 stainless steel body resists scaling and oxidation better than FRP alternatives, while the glass fiber reinforced nylon end cap keeps weight manageable without sacrificing pressure ratings.
Material Specifications
| Housing Body | 304 Stainless Steel |
| End Cap | Glass fiber reinforced polyamide thermoplastic nylon |
| O-Ring/U-Packing | EPDM |
| Clip & Fasteners | 304 Stainless Steel |
| Membrane Size | 4" x 40" |
| Port Size | 1/2" NPT |
| Maximum Pressure | 300 PSI |
Membrane Fit
Accepts all standard 4" x 40" RO membranes including Filmtec, Hydranautics, Toray, and CSM models. The SSMH-4040-12 works in municipal water treatment, commercial beverage applications, aquaculture systems, and light industrial process water where stainless construction is preferred over fiberglass for cleaning protocols or sanitation requirements.
