Overview
KIT-MB-40F is the long, narrow seawater membrane and seal kit for Spectra’s documented 2.5 × 40-inch installations. It replaces the element inside the existing pressure vessel.
The current Newport fact sheets show why order quantity matters: a standard Newport 400C has one 2.5 × 40-inch element, a Newport 700C has two, and a Newport 1000C has three. Those counts apply to the named standard arrangements.
The Newport 400C Compact uses two short 20-inch elements instead. Selecting “Newport 400” without identifying the vessel arrangement can therefore lead to the wrong kit.

FAQs
Does one kit replace every membrane on a multi-element watermaker?
No. Order by the number of individual elements being replaced. “40-inch kit” describes the element format, not a complete multi-vessel set.
