These standard RO membrane housings are long-lasting and offer wide membrane compatibility. Membrane housings are relatively standard across the industry, and these housings will fit standard 10" RO membranes, such as the popular Dow Filmtec 75 GPD membranes. Made with high-quality components and o-rings, they are the perfect option for building your RO/DI system or replacing a worn-out membrane housing.

 

For the most part, the only wearable parts are the o-rings that seal the housing. If the o-rings are kept properly lubricated, they will often last years without any problems. However, over time the o-rings can wear out or deform, and with slight variations in tolerances of o-rings and housings over time, it's often easier purchasing an entire new housing.

 

Most common fittings used -

Source water input: 1/8" MNPT x 1/4" Push Connect

Waste water output: 1/8" MNPT x 1/4" Push Connect

Product water output: 1/8" MNPT x 1/4" Push Connect Check Valve

 

Note: Housing has 1/8" Female NPT Fittings. We highly recommend the use of a push connect elbow check valve on the product water line if you are going to use an auto shut off valve on your RODI system.  The use of a non-check push connect elbow is totally fine, as inline check valves can be added at any time.

Product Questions

What size fittings will fit this housing? It has been noted in previous reviews that standard 1/4" female elbows do not fit. Kinda important info that should be included in description. Don't you think?

Hi Milo,
The membrane housing is a standard membrane housing which utlize 1/8" female npt fittings. The most common fittings to use in them would be 1/8" male NPT fittings x 1/4" push connect like the one found at the link below

What is the housing material made from?
Question by: KELSEY ANTHIS on Apr 25, 2017, 11:26 PM
Hey there,
The clear water filter housings are made of a plastic material called Styrene-Acrylonitrile which provides a safe operating range up to about 90psi.

Happy reefing!

Is there a wrench or tool to remove the caps from the R/O housing? I just replaced my membranes and found the caps very difficult to remove.
Question by: chad bisbing on Jan 25, 2018, 8:33 AM
We do not have a specific tool to remove the membrane housing caps, but sometimes soaking the cap in hot water for 5 minutes can help, but if that doesn't do it either a strap wrench or a properly sized oil filter wrench works well too.

What size fittings will this RO housing need on the cap?
Question by: Justin on Feb 20, 2014, 3:53 PM
Hi Justin,
The threaded fittings on the cap (and other end) are 1/8" NPT, so to use them one would generally use a 1/8" NPT x 1/4" push connect.

If I currently have a 50gpd 4 stage ro/di could I add a second RO membrane and double the output?
Question by: Shane on Feb 1, 2016, 3:23 PM
Great question!
You certainly can add a second water saver membrane onto the system. Keep in mind that the membranes will need to be the same size. For example if you have a 50 gpd membrane your second will also need to be the same size due to the flow restrictor. If you change your current membrane to a 75GPD you can simply change the flow restrictor to one which is closer to 550 mL per minute. Feel free to let us know if you have any further questions!

What is the thread size on the inlet/outlet for this?
Question by: Drew on Feb 24, 2014, 5:48 AM
-1
The threads on the membrane housing are all 1/8" NPT so most folks will use a 1/8" male NPT x 1/4" push connect fitting on them.
