Marine wet exhaust hoses

High performance silicone hoses

Silicone and EPDM Marine hoses with Lloyds approval

Flexible connections for marine engine wet exhaust systems:  From engine exhaust manifold to hull or overboard discharge.

Likon offers a range of high performance silicone straights, elbows and bellows for use as marine wet exhaust hoses, and other marine hoses. Manufactured using only the highest quality silicone the hoses are constructed in 4 to 6 ply polyester with blue silicone for use up to 180°C. A special liner in the hoses prevents attack by sulphurous fumes in the exhaust. For higher temperature applications up to 260°C, 4 to 6 ply meta-aramide fabric is used with silicone in red iron oxide colour.

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!!
