Hinged Lids

The hinged lid is manufactured from a co-polymer material for strength, durability and excellent chemical resistance. Norwesco’s unique locking tab allows you to easily slip a padlock through it and secure your lid from theft or spills. The lid is interchangeable with a standard 22″ or 16″ lid and ring assembly if you choose to replace your existing lid.

Features of Hinged Lid:

  • Easy open/close – opens a full 180 degrees
  • Comes complete with a baffle vent assembly which allows for adequate venting when bottom filling your tank
  • Unique locking tab
  • All parts of lid may be ordered as repair parts

Stainless Steel Double Threaded Bolted Full Coupling Fittings

Bolts are threaded into the back plate of the fitting so there are no welds or bolt holes that can be potential points of leakage. Please review chart below to see which fittings come standard with a gasket and which ones come without a gasket.  The gasket should be installed inside of the tank. Available gaskets are cross-linked polyethylene, EPDM or Viton.
