Re: Stus-List Connection fittings for corrugated bilge pump hose
Eric, I'd either try 1 some silicone sealant 2 I would get a piece of plastic pipe that fits inside the corrugated hose (like a kitchen tailpiece pipe) and figure out how to connect it to the strainer or 3 see if West will sell you a short piece of the new stuff and use a coupling to join the new hose to the old.

Stus-List Connection fittings for corrugated bilge pump hose

Re: Stus-List Connection fittings for corrugated bilge pump hose
Those hoses with the non-corrigated sections are of poorer quality and will not likely last very long. The Shields 141 hose is a reasonable value for bildge hose.

Re: Stus-List Connection fittings for corrugated bilge pump hose
I would try some KY to lubricate the threads so you can get the fitting tighter. I don't know exactly what type of fitting you have but a hose coupling like the one in this link will allow you to screw to pieces of 1.5 corigated hose together. Again more KY. http://www.grabberpower.com/images/vac_accessory_7.png You might also find that an inline check valve or a foot valve helps keep the suction line primed. Beckson makes one. Evidently, on inspected vessels the coast gaurd wants the suction strainer to be 3x the area of the suction hose so this doesn't meet that requirement but then again it is pretty unlikely that you have an inspected vessel. http://www.beckson.com/images/STV-1-1_2at600.jpg http://www.beckson.com/hose.html Josh Muckley S/V Sea Hawk 1989 CC 37+ Solomons, MD On Apr 27, 2015 8:59 AM, Eric Frank via CnC-List cnc-list@cnc-list.com wrote: The 1.5 inch ID corrugated hose that runs from the bilge to a manual pump in the cockpit seems to be leaking in air just where the corrugated hose connects to an adaptor that screws into the hose with the threads of the corrugation and then provides a male 1.5 inch end that fits inside the strainer.

Re: Stus-List Connection fittings for corrugated bilge pump hose
Thanks to all of you who contributed answers to my question. It seems quite clear from the responses that to fix this properly, the hose should be replaced. Fortunately that can be done after Cat's Paw is back in the water. As others have noted, this list is great. I just asked this question this morning!
