    Has anyone installed or seen silicone hose used as a substitute for Algonquin packing box hose? I’m thinking of using something similar to the blue silicone bellows hose used for dripless face seals. Some of the high heat/ burst pressure silicone hoses used for auto exhaust also look promising. There’s also wire reinforced hose. Any thoughts?

    I wouldn’t. Never seen it and don’t think torsional strength is there.

    Talk to the people at Tides- very good people and boat people not just engineers so odds are they will have an answer based on their experience.

    I am right in the middle of the same issue on one of our boats. I need a 5-1/2" hose which no one makes anymore. I looked at the blue Tides hoses but could not find a match and decided against it anyway. My hose is 1/2" thick and what I believe they call a 5 ply. I finally found something from Parker so I went with that. Just don't trust going so much thinner

    No, no, & no. Has no strength, even exhaust hose isn't strong enough.

    I would only use Algonquin hose or equivalent. It has the necessary torque strength. Anything else would be suspect and if it fails and your boat sinks, your insurance may not cover you.

    I got ya now, sorry I wasn’t thinking. I actually thought about dredge pipe hose but not clam hose. Worth looking into

    May be just me but I wouldn't use anything not specifically engineered for that purpose given a failure can quickly turn your boat into an artificial reef. There are plenty of other places on a boat that I would that but not there

    RE Thomas did not carry 5 1/2” hose but he said he gets his hose from complete hydraulics in Plymouth Maine. I’ll give them a call in am for you if you want

    Well I do have some coming from Parker tomorrow. Allegedly. I used to get it from Amazon in Tampa but no more. Let me see what shakes out first. Help like this is always appreciated.
