To change the connections on an NW32 filter from 1 1/4" to 1". Complete set containing 2 nipples, 2 lock nuts and 2 gaskets.
Fits all filters in the NW32 series such as NW32 Particle, NW32 Carbon, NW32 Duo and NW32 Trio (also fits NW18/NW25 series).
NB! Delivered twice as much as the photo shows as 2 connections are needed to change at each end of the filter. Keep in mind that the flow through the filter will be slightly throttled when you reduce the connection..
