Forespar MF 846 Vent Barb Assembly
- The Forespar MF846 vent barb assembly is an option that can be used in place of the standard MF841 cap / duckbill
- This option allows venting to the outside of the hull via a 1/4" hose.
General Note: Forespar threaded plumbing fittings (like most true marine plumbing fittings) use NPSM Threads - National Standard Free-Fitting Straight Mechanical Pipe Thread. NPT - National Pipe Threads are tapered, NPSM Threads are parallel. The two types are not designed to work together.
