Flange Accessory Kits

Spec Rubber offers Flange Accessory kits specifically designed for use with Ductile Iron Pipe applications. Our kits come with a gasket, an essential component that acts as an air and water-tight seal between two pipe ends. When secured with nuts and bolts, the gasket is compressed to seal any air gaps, ensuring a reliable connection. Our gaskets are also designed to prevent any contamination of fluids within the piping system. Standard kits for nominal pipe sizes 2″-12″ include a 1/8″ thick NSF-61 EPDM Flange Gasket or SBR Toruseal Flange Gasket. We also offer customizable kits to meet your specific needs, including options for gasket materials, hardware materials, and import or domestic applications.
