Membrane compatibility\u003c\/h3\u003e\n\u003cp\u003eCheck that the housing is designed for the membrane format you intend to use.

Inlet and outlet connections\u003c\/h3\u003e\n\u003cp\u003eCheck 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.\u003c\/p\u003e\n\u003ch3\u003e3. Pressure rating\u003c\/h3\u003e\n\u003cp\u003eReverse 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.\u003c\/p\u003e\n\u003ch3\u003e4. Seals and O-rings\u003c\/h3\u003e\n\u003cp\u003eCheck 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.\u003c\/p\u003e\n\u003ch3\u003e5.
