PAMTIGHT manhole covers are the optimum choice for applications where air and water tightness are required. Made from ductile iron — an engineered material that offers many advantages over traditional cast iron — PAMTIGHT covers deliver unsurpassed performance in all the key areas of concern to municipal engineers.
PAMTIGHT manhole covers are designed to prevent the infiltration or escape of air and water to a 14-psi (1-bar) positive or negative pressure rating
• Elastomer sealing ring ensures watertightness
• Fastening design (six bolts, clamping claws) allows higher performance sealing
• After opening, cover can be put back in any orientation and remain pressure tight

PAMTIGHT manhole covers are designed for safe use by installers and maintenance personnel.
• Ductile iron — Product weighs 50% less than typical cast iron covers, reducing risks of manual material handling (MMH) • Safe mode of failure — even in unlikely event that cover dishes and/or cracks, it remains strong and therefore protects the public from accidents

PAMTIGHT manhole covers are designed to be highly durable, a benefit that is made possible by the excellent mechanical performance of ductile
iron.
• Three times the load strength of typical cast iron covers
• Polyethylene seating ring ensures perfect seating, resistance to traffic shock
