PureT (SSMH-4021-12) 4" x 21" x 1/2" 304 Stainless Steel Membrane Housing, With Plastic End Cap

The PureT SSMH-4021-12 is a 4" x 21" commercial-grade membrane housing machined from 304 stainless steel, built to handle up to 300 PSI in demanding reverse osmosis installations. Its corrosion-resistant construction and reinforced plastic end cap make it ideal for high-pressure commercial water treatment systems where durability and reliability are non-negotiable.

COMPATIBILITY & APPLICATIONS

Where This Housing Works

The PureT SSMH-4021-12 membrane housing is designed for commercial reverse osmosis systems requiring a 4" x 21" membrane configuration. Its 304 stainless steel construction makes it suitable for food service, light industrial, and high-traffic commercial water treatment applications where plastic housings may not withstand the pressure or longevity requirements. The 1/2" port size accommodates standard commercial RO membrane configurations. The reinforced plastic end cap balances weight reduction with structural integrity, while EPDM seals provide reliable performance across a wide temperature range. This housing is built for operators who need commercial-grade durability without the cost and weight of full stainless steel construction throughout.

💧 Pro Tip: Always replace EPDM seals when reassembling the housing after membrane changes. Reusing old seals is the most common cause of slow leaks in stainless steel membrane housings, especially in high-pressure commercial systems.
