The Monitor Premium Watertight Well Cap secures to the pitless casing with a compression gasket for a truly watertight closure. The top removes without disturbing the seal, conduit, or wiring, and it can serve as a vacuum seal to 20 psi when the conduit is plugged.
Cast from high quality gray iron, painted green and oven-dried, with stainless steel hardware. Select by casing outside diameter. For a factory-vented version, see the Monitor Premium Watertight Cap with Screened Air Vent.
