Fire Resistant Hose for Cockpit Drains

[lpdsn]

The hose for my cockpit drains passes through the engine compartment to seacocks behind the keel. The current ones are insulated but they're getting a bit old, so it is probably time to start thinking about replacement.

Obviously if the hose burns through in a fire the boat will sink, which whilst it may well put out the fire would be otherwise quite awkward.

Does anyone know of a supplier of decent fire-resistant hose? The diameter in 1.25".

I believe that wet exhaust hose is suitable. It is required on a coded boats for such applications, when all hoses below water level have to be fire rated. Here is a link ( http://www.sealsdirect.co.uk/shopping.asp?intDepartmentId=6#53 ).

Alternatively or as well Aviation parts suppliers should be able to supply a stainless steel mesh cover to go over the hoses to deflect heat so improving fire resistance. olewill

Mine are fire resistant fuel hose as described in the link above.

Similar to this which is 32mm: http://www.asap-supplies.com/marine/superflex-fuel-hose-seaflow/seaflow-iso7840-fuel-hose-305832

although since you'll not need the requirement for fuel delivery through them, ASAP also do a fire retardant water delivery hose which is a little better in terms of price.. It might not look exactly like the picture though

Agreed and even cheaper for the 32mm!

Speed reading, late at night is not conducive to getting things right...

On coded boat is it not just hoses within engine compartments that need to be fire resistant?

You are probably right, need to ask a surveyor I guess, or read through MGN 280. On ours, all the hoses in the engine room are fire rated. In the separate hold/lazarette those hoses supplying the generator needed to be fire rated as well as those to the deck wash pump. However those hoses supplying the heads forward in a separate hull compartment are just standard hoses.

The OP was describing deck drain hoses passing through the engine room and my reply was a bit sloppy and assumed that we we discussing hoses passing through an engine compartment.

Thanks for your answers everyone. Looks like the asap link will do the business.
