While a well-cared for membrane will last many years, they may need to be replaced in the lifetime of your watermaker. This kit includes DOW Filmtec seawater membranes (or equivalent) with all seals required for replacement.

Please note that this membrane is the 2.5″ x 40″ membrane good for any RO system that needs a replacement.

Spectra Customers!: This is NOT an OEM part and if your watermaker system is still under any factory warranty purchasing this membrane may lead to negating and / or voiding current or future warranty claims.

Halden Marine Service uses these membranes as a replacement aftermarket and can be used for multiple RO systems.

This part is always in stock and available in our warehouse.
