Need to replace the hoses from the seawater intake that cool the gear box oil....two questions please. Can I use hose from my local industrial hose supplier or car factor, or do I have to pay Volvo prices?? It will be an over the engine job with a mirror and torch..what best to lube the hose with..washing up liquid or can I use silicon grease?? Engine is a Volvo 2010
 
Cue for photo, surely?....

I suppose I asked for it /forums/images/graemlins/smile.gif.... but where are the practical replies???? Or is KY really the best thing to use ???? A bit pricey !!
 
I'm being serious. Lots of lubricants you may think of using attack rubber. Silicone ones may leave the hose liable to coming off. I don't know about Fairy Liquid long term, but if you rub the end of your hose with Swarfega for instance you'll get a black mess on your fingers, so it aint doing the rubber much good.

feel free to insert "Oh, Err, Missus" wherever applicable.
 
Garages have lubricated coolant hoses with Swarfega, Teepol or washing up liquid ever since the internal combustion engine was invented. Any half decent rubber-based hose will be either nitrile or neoprene based, either of which is pretty much 100% inert to detergents. I wouldn't use silicone lubricants because they are insoluble in water and will remain slippery for some time, with a possible risk that the hose will slip off. There is absolutely no problem with detergents. Any black that may rub off is simply a small amount of the carbon filler that is being removed. Exactly the same would happen if you rubbed it with a dry hand. The base elastomer will not be attacked by either hot or cold water, detergent, oil or many chemicals. Let's not invent problems where none exist.
 
silicon grease is too slippy by far - on a straight hose connection you can rotate/pull the hose off even with the clips done up tight.

I prefer tyre-fitting lube. Available in spray cans or nick some from your local tyre place. nice n slippery.... doesn't attack rubber ( you think? ) & dries out after a while. Perfect

But a hose behind a hot engine that you can't even see pops off at sea when you're trying to clear a lee shore.

A little bit of caution could be exercised. Because that problem may exist.
 
Plumbers merchants carry drain pipe assembly lubricant. Slippier than washing up liquid and ok for rubber. There's even one for potable water. Gel type dries out after time so that it doesn't leave a tendency to slip apart.
Screwfix do it
 
just done the job, undid the 2 * 6 mm nuts, 10mm spanner, used a stanley knife to cut at a slant to get the old off, tight as hell, used 3/4" wagon heater hose, spot on size, bit of spit and it slipped on grand. as others have said, all my maintenance life have used any from swarfega to washing up liquid, never a moments prob.

Red rubber grease for hydraulic systems doe not attack rubber.

I don't think he wants it to slip off when at sea.
 
That sounds ideal. Like KY jelly in bulk.
In fact you could repackage it in smaller, pink tubes, and there's bound to be a market for it. /forums/images/graemlins/smile.gif
