HOSE - HIGH FLEX

Has anyone tried this super high flex hose?

It looks like it would do about everything needed on the engine & replace all of the preformed specialty bends. I plan to call them to ask about wet exhaust. I have a 24" X 1" sample. Its as easy to bend as the photo indicates.

If that can be used in wet exhaust systems, it would be worth a great deal to me...I'd only need about 18 inches, though.

Re: HOSE - HIGH FLEX

I think the oily exhaust would restrict you to the MP hose, and that may not handle the heat

Quite possibly. My wife works in a chandlery so I'll get her to figure this out. A properly bent T-fitting in galvanized pipe would serve me just as well, but I can see other uses for scuppers and so on.

I figure water & glycol lines on the engine.

Re: HOSE - HIGH FLEX

One issue I have come across when replacing preformed hose with flex hoses is they never want stay bent in the position you put them in. Especially longer runs, they sag and wear on fixed item or belts. So unless you have a way to secure them well use the preformed.
And I don't think this would be rated marine exhaust.

Re: HOSE - HIGH FLEX

so - I called Parker's tech service today. The hose is OK for glycol and cooling water or anywhere else you might think of. It is not CG certified for Wet exhaust. You would have to use MP hose for exhaust due to the diesel oil. (EPDM vs Nitrile) Temperature rating is nominally only 180 F but I was told that 200 is OK. You might keep some around as an emergency replacement - easy to store. I might consider it for the exhaust from the muffler to the through-hull. Other than that, I plan to buy several different sizes for the cooling and bilge system.

I work with Eaton /Aeroquip hose and fittings. Eaton offers a product a product with a blended compound call AQP which gives a 300 degree continuous working temperature Click image for larger version

The AQP compound in the attachment is a comparable construction to a wet exhaust hose but is offered for higher pressure applications.
Look up your local Eaton Hydraulic Hose representative for the most part it's readily availableClick image for larger version
