EDPM puddle flanges: NBR puddle flanges available.


Puddle flanges WA-PF models have raised profile ridges on the collar that create a bonding surface with concrete.

EDPM elastomer collars are thick disk materials that compressed during the concrete pouring process and relaxes into shrink cavities during the concrete drying process. EDPM rubber disks units are pressure-tight up to 145 psi (10 bar).

The rubber density is 1030 Kg/m cube with a tensile strength of 8/N/mm square. They prevent water creep along the pipe exterior into a structure.-puddle-flange-pool-wall-sleeve

316L stainless steel tightening bands firmly attach the puddle flange to the pipe.
