Product Description
Our Hatch Packing is manufactured from three different rubber compounds and a range of different sized profiles. Our watertight hatch seals for cargo covers and access doors are used on many vessels including: naval ships, cruise ships, ferry lines and oil, gas and chemical tankers. Hatch packing is used for watertight doors, skylights, ullage plugs and other comparable marine applications.
Our RubbaHatch® combination seal is our most popular composite hatch packing seal supplying marine clients worldwide. It is comprised of a closed cell sponge sealing material with a thin outer skin of solid rubber to provide added strength and durability. 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
- Neoprene Rubber – for high temp and ozone resistance
- Nitrile Rubber – for gas and oil resistance
RubbaHatch-S®
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.
RubbaHatch-SP®
This is our high-density, closed cell sponge that has been specifically manufactured for use in hatch sealing applications. Our RubbaHatch-SP® allows for a variety of compression rates in order to ensure you get an airtight as well as watertight seal, without deteriorating the material.
