4" Tri Clamp Reducer - Spool Reducer or Cap in 3/8" or 1/2" MNPT

This hemispherical reducer features a unique set of features in that it reduces from a Tri Clamp fitting to a NPT fitting. It’s made of 304 stainless steel, and will reduce from 4” Tri Clamp connections to 3/8" to 1/2" MNPT connections. 

This is your solution to different fitting needs, and carries the possibility of a pressure build up.

Our hemispherical reducer is recommended for connections at the base or top of spools, filter driers, manifolds, and all other locations where great reduction is generally helpful.
