Stainless Steel Oval Manway NKA 7027

Overview

This cover is used primarily in storage tanks in the beverage industry. It seals from the inside, however its oval shape also allows it to be removed from the tank. When a pivoting mechanism is attached, the cover can also be pivoted to the outside without removing it completely from the tank. The standard version of this seal sits loose on the cover, however the seal can also be vulcanized on.
