This hemispherical lid features a unique set of features in that it reduces from a NPT fitting to a Tri Clamp fitting with a showerhead for distributing solvent evenly threw the column. It’s made of 304 stainless steel, and will reduce from 6” 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.
