EDPM puddle flanges: NBR rubber puddle flanges available.


Puddle flanges
WA-PF models have raised profile ridges on the collar creating a bonding surface for concrete.

EDPM elastomer collars thick disk materials 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.

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

Puddle flanges Watertight collars floor units

Cast in a floor slaps to waterproof pipes that are installed through the floor. EDPM rubber is resistant to a wide range of acids and chemicals.
