The wrong hose for your application can make for a smelly situation... literally. First know your size. Marine sanitation hose is available from 5/8 up to 1-1/2 inch diameter. Determine the size hose you'll need (and any clamps too) before you buy. Marine sanitation hose also comes in a varity of colors including white with a blue stripe which may be an easy identifier for you while you are in the bilge one day! Wire or PVC wire reinforcement is also a choice to consider before you buy.
All of the marine sanitary hoses at Defender Marine are top of the line odor free (just be sure your fittings are tight). Optional smooth wall finishes make for a speedier installation and may be the smart choice for the weekend warrior with more guts that actual repair experience.
The old saying "get what you pay for" holds true right here - the best marine sanitation hose is simply not cheap. So know how much you need before you buy and buy only what you need.
