Water Hose - Hard Water Deposits

Is there any product that can safely be used on the threads of drinking hose connectors to prevent keep hard water deposits from cementing them together? I use quick disconnects and cutoff valves on my water hoses and after just a short period of time hard water deposits make them almost impossible to get get apart. Is there any type of "grease" or other product that that will prevent this?

Well I hadn't thought of corrosion but guess it could be that. Whatever it is I'd sure like to prevent it happening.

the same products used to maintain tank drain valves work great on hose connectors...

aerosal spray or grease versions.

these are commonly used as O ring lubricants in drinking water systems.

http://www.airforums.com/forums/f514...ain-72998.html

web search 'food grade silicone' for a lot of vendors.

the sprays will collect less grit than the grease,

but a thin film of grease will last much longer.

plumber's grease from gunk is a common brand available.

________

the problem is typically galvanic corrosion mixed with mineral deposits.

switching all the connectors to brass or steel or nylon helps too,

but 1 can of spray and 1 tiny tub of grease will last for years.

the spray is used with window seals, door gaskets and lots of other bits around the trailer.

cheers

Thanks for the info. Will be heading for the hardware store in the morning to see if they have the Gunk Silicone Grease. Will be happy to get this problem solved and once again Air Forums comes thru with flying colors!
