Access Doors, Storage Covers, and Tank Hatches
As a safety precaution, all equipment should be locked-out before opening these covers.
Round Non-Pressure-Rated Covers
Commonly used as clean-outs, fill openings, inspection doors, access covers for repairs, and sampling ports. No tools are required to open plus most can be locked shut to prevent unauthorized access.
Gaskets are an integral component so as to reduce dust and water contamination. Gasket options include black buna n, epdm, garlock, hi-temp, teflon (or teflon envelope), white neoprene, and viton.
