High-Pressure 20-Inch and 40-Inch Membrane Housing

Proudly made in the USA, this premium housing is constructed from durable epoxy resin and rated for 5,000 PSI burst pressure. It features stainless steel tie rods and double O-ring, Teflon-coated corrosion-resistant end caps for maximum durability and leak protection. This is the highest-quality membrane housing available.

Each unit comes pre-installed with a seawater series reverse osmosis membrane, ready to connect and operate right out of the box.

What is the function of the 40-inch reverse osmosis membrane?

The 40-inch membrane is the heart of the reverse osmosis system. It removes salt, minerals, and other contaminants from seawater, delivering pure, drinkable freshwater for marine, industrial, and residential applications.

How often should I replace the RO membrane?

With proper flushing and regular maintenance, RO membranes typically last 3 to 5 years. Actual lifespan depends on usage, feedwater quality, and system care.
