Our RubbaHatch® combination seal is our most popular rubber hatch seal supplying marine clients worldwide.

The cellular sponge core is purpose made for RubbaHatch® with excellent flexibility and compression properties, allowing for general duty and water tight installation in marine hatch and door flanges. Supplied with chamfered edges to assist with installation.

Material Selection

The Rubber Company can offer three different types of rubber for the sealing face dependant on the customers specification and application:

Natural Rubber for general purpose use.

Our RubbaHatch-S® is a solid rubber extruded seal, as with our composite hatch packing, we can supply with chamfered corners to assist installation and cater for troublesome welds at the base of the fabricated recess. A hollow section improves the seal’s compressibility and its response to clamping pressure.
