Revenue model

1. Rubber Gasket and Sealing Product Sales: Hamilton Kent generates revenue through the manufacture and direct sale of rubber gaskets, sealing systems, and components for infrastructure pipe applications. Products include concrete pipe gaskets, manhole connectors, plastic pipe gaskets, bridge expansion joints, and mechanical couplings. Both standard catalog items and custom-designed products are sold.
2. Straub Mechanical Coupling Distribution: As the exclusive North American partner for Straub mechanical couplings, Hamilton Kent distributes Straub joining, repair, testing, and marine couplings. This is a complementary product line sold alongside Hamilton Kent's own gasket portfolio.

• Tylox WT+, WT, and ST Cast-in Connectors Cast-in pipe-to-manhole connectors that replace mortared pipe connections so structures arrive at the jobsite ready to install.
• Tylox XT Cast-in Connector Push-fit cast-in connector that replaces mortared joints on the jobsite; installs with no special tools and creates a strong watertight connection with all pipe types.
• Tylox 3SPW Glued Manhole Connector Economical push-fit gasket specifically designed for connecting PVC pipe to a concrete structure, creating a watertight seal by inserting the pipe into the structure.
• Tylox HKT Compression-Fit Connector Compression-fit connector that replaces mortared joints, creating a permanent watertight connection between PVC pipe and a precast concrete structure or concrete pipe.
• PVC/PVCO Pipe Gaskets Rubber gaskets providing watertight or silt-tight pipe connections for water, sanitary, industrial, storm drain, mining, and culvert applications using PVC and PVCO pipe.
• Plastic Drainage Pipe Gaskets Rubber gaskets designed specifically for HDPE and PP pipe joint designs and pipe materials to ensure watertight drainage connections.
• Expansion Joints for Roadways, Bridges, and Parking Structures Custom rubber extrusions accommodating up to 12 inches of thermal, traffic, and structural movement in bridges and roads.
