PAMTight Manhole Covers
• PRESSURE TIGHT DESIGN
• DURABILITY
• SAFETY

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.

Pressure Tight Design

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

Durability

back to top

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

Safety

back to top

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
