Thick solid rubber skin – sponge rubber core

Dual hardness, reduced compression force


Dual hardness rubber packings for compression sealing of yacht and commercial ships doors and hatches. These rubber marine packings are made with a thick, wear resistant solid rubber outer skin that protects the compressible sponge rubber core.

Suited for large transom doors, tender garages and terraces.


Available sizes




The skin is much thicker than the skin you’ll find on normal sponge and cell rubber. It is hard wearing and resistant to cuts. It does have to be inspected regularly since the sponge rubber core isn’t water tight.

Keeping up with COVID-19

This rapidly evolving corona-virus (COVID-19) has imposed an unsettling, fluid situation upon our community and its businesses. While the team here still aims to maintain a “business as usual” approach, we are making a number of significant changes to our operations to account for a situation that is far from normal. Governmental orders in the fight against the spread of the corona-virus (COVID-19) lead to the partial or complete closing of several production lines or designation of lines for the production of crucial parts for essential industries like food and pharma. As a direct result confirmed or usual lead times may not be met. In the current situation the delay cannot be determined. With the closing of factories in certain areas we need to make some changes to standard terms. To can keep operational and safeguard our financial position we must change certain terms. These will be announced and confirmed upon receipt of orders. Apologies for the inconvenience. Take care of yourself so you can take care of others!!
