Hygienic Oval Manhole Covers are specialized tank access points designed primarily for inward-opening applications. Their unique elliptical shape allows the cover to be turned and removed through the opening it seals. This design uses internal tank pressure to tighten the seal against the gasket, making them exceptionally safe for pressurized liquid storage. Made from 316L or 304 Stainless Steel, they are common in wine, dairy, and brewing for side-wall entry.
