Reverse Osmosis Membrane Housings & Accessories

A reverse osmosis membrane housing holds and protects the membrane element within a reverse osmosis water filtration system. It provides a sealed chamber through which feed water passes under pressure, allowing the membrane to separate permeate from the concentrate stream.

At GroAqua, we stock reverse osmosis membrane housings and replacement components for compatible water filtration installations. Our range includes compact 1812 membrane housings and replacement sealing components, helping you maintain or repair an existing RO system.

Whether you are building a domestic reverse osmosis system, replacing a worn housing or sourcing an O-ring for routine maintenance, choosing the correct component is essential for a secure and compatible installation.

1812 Reverse Osmosis Membrane Housings

The 1812 designation is commonly used for compact reverse osmosis membrane elements and their corresponding housings in domestic water filtration systems.

A compatible 1812 membrane housing provides an enclosed chamber for the RO membrane and connects it to the system's feed water, permeate and concentrate plumbing.

The PRISM Core 1812 membrane housing in our range features:

• A housing designed for compatible 1812 reverse osmosis membranes.

• A 1/4-inch inlet connection.

• A 1/8-inch outlet connection.

• A compact format for suitable domestic and point-of-use RO installations.

Always check the housing's dimensions, port arrangement, thread type and connection sizes before purchasing. The 1812 designation relates to the membrane format and does not guarantee that every 1812 housing is interchangeable.

Replacement RO Membrane Housing O-Rings

O-rings are important sealing components within a reverse osmosis membrane housing. They help create a watertight seal between the housing components and prevent water from escaping during operation.

Over time, seals can become worn, displaced or damaged. Replacing a compatible O-ring may help restore the seal without requiring the entire membrane housing to be replaced.

GroAqua stocks replacement upper and lower O-rings for the Aquafilter YT-25W RO membrane housing.

Before ordering replacement seals, check:

• The exact membrane housing model.

• The position of the seal within the housing.

• The required O-ring dimensions and profile.

• Material compatibility with the operating conditions.

• Whether the replacement includes the upper seal, lower seal or both.

Using the correct replacement seal is important for maintaining a secure housing connection.

Choosing the Correct Reverse Osmosis Housing

Not all RO membrane housings are the same. Even when two housings are designed for similar membrane sizes, their dimensions, ports and sealing arrangements may differ.

Consider the following before selecting a replacement:

1. Membrane compatibility

Check that the housing is designed for the membrane format you intend to use. Domestic systems commonly use 1812 membrane elements, but larger commercial systems require different housing designs.

2. Inlet and outlet connections

Check the inlet and outlet sizes, thread types and connection arrangements. The fittings must match your existing RO pipework or be suitable for the adapters used in your installation.

3. Pressure rating

Reverse osmosis systems operate under pressure. Confirm that the housing's rated operating pressure is suitable for your system and never exceed the manufacturer's specified maximum pressure.

4. Seals and O-rings

Check the number, position and dimensions of the required seals. A housing with an incompatible or damaged O-ring may leak even if the main housing body is in good condition.

5. Installation space

Allow sufficient room for pipe connections, access and future membrane replacement. This is particularly important in compact under-sink RO installations.

Maintaining Your RO Membrane Housing

Regular inspection helps identify problems before they affect the operation of your water filtration system.

Useful maintenance practices include:

• Inspect the housing for visible cracks, damage or signs of leakage.

• Check connections and fittings for signs of water escaping.

• Examine accessible O-rings and sealing surfaces when servicing the housing.

• Replace damaged or unsuitable seals with the correct components.

• Follow the manufacturer's instructions when opening, cleaning and reassembling the housing.

• Check that the system is correctly depressurised before carrying out maintenance.

Do not attempt to open a pressurised membrane housing. Isolate the water supply and release system pressure according to the manufacturer's instructions before servicing.

Complete Your Reverse Osmosis Installation

A membrane housing is just one component of a complete reverse osmosis system. Depending on your installation, you may also need a compatible RO membrane, sediment and carbon pre-filters, post-filtration cartridges, tubing and connection fittings.
