New 7 " Threaded Lids Available 

Den Hartog Industries is proud to announce the newest addition to our line of Accessories, Lids and Fittings with a new 7" threaded polypropylene lid. 

8" R.H. Buttress-style threads and ear tabs are available for lanyard attachment.

Options:

Non-Vented - does not allow air exhange in or out of tank

Spring Loaded Vent - allows air into the tank

Two-way Stepped vent -allows air exchange in or out of the tank

Our innovative step vent prevents the tank contents from sloshing out. 

The Lid and Step Vent are produced from injection-molded polypropylene and are black in color. 

The vent is sonic welded to the inside of the lid.  The Step Vent is preferred by customers who bottom-fill their tanks.

A gasket will soon be available to seal the lid to the tank.
