RO Membrane Housing O-Ring- Suitable for Membrane housings

Great for replacing your old membrane O-Rings.

An O-ring is also known as a packing or a toric joint. It is a mechanical gasket in the shape of a torus. It is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts. Therefore creating a seal at the interface.

All of our housing O-rings are here  If this one doesn’t suit you, check these other ones out.

O-rings need regular maintenance. Having said that, you should also not overdo it. O-rings need to be maintained flexible with silicone gel. Grease doesn´t not have sealing properties, in too large amounts it only does harm, attracts dirt and sand and can therefore result in a defect in liquid tightness. You should only grease those O-rings which you can reach without dismantling the housing or the port.

If your housing is leaking, it could be a number of things such as:

From the joint of the lid of the housing
  • -O ring could be squashed meaning the head has been put on too tight
  • -O ring could need silicone gel
Leaking from the in and out area either side of the housing
  • -connection could be too tight and it has a fractured housing
  • -may need more plumbing tape around the threaded end of the connector where it screws into the housing (spare connectors and tape available from us)
  • -tubing may be loose or not pushed in far enough
In conclusion, if it’s leaking elsewhere, we suggest replacing the housing
