Scuba Forum / General / August 2005Lubricating low pressure hose
My low pressure hose to my dry suit is getting quite difficult to remove, which is a bit worrying in case I need to disconnect in a hurry. What is the best sort of lubricant to use (obviously anything above water would simply get sprayed with WD40 but I'm not sure this is a good idea for an LP connector). > My low pressure hose to my dry suit is getting quite difficult to > remove, which is a bit worrying in case I need to disconnect in a hurry. > What is the best sort of lubricant to use (obviously anything above > water would simply get sprayed with WD40 but I'm not sure this is a good > idea for an LP connector). Mine normally cakes up with chalk from being hosed off and left to drip dry so a quick flash in Viakal or Lemon juice before some silicon grease helps. Nobody much likes puting hydrocarbon based lubricants around high pressure gases. nigelH > Mine normally cakes up with chalk from being hosed off and left > to drip dry so a quick flash in Viakal or Lemon juice before > some silicon grease helps.

Never use any petroleum product *especially WD40* on diving gear. It will turn rubber into a sticky goo. Usu silicone or, better yet, Cryslo Lube. Safe diving, Cpt.

You can take it apart by carefully removing the thin retaining ring, but do it over a towel so as not to lose any of the balls. Dip it into some CLR (do not get it deep enough to dip the hose) for a few minutes, then rinse real well and lube it with Christolube or Krytox: The lube will help keep the balls in place for re-assembly. http://www.jelmar.com/CLRbasic.asp http://www.dupont.com/lubricants/en/index.html http://www.miller-stephenson.com/home_008.htm > My low pressure hose to my dry suit is getting quite difficult to remove, > which is a bit worrying in case I need to disconnect in a hurry.

An ultrasonic cleaning might not be a bad idea. Ultrasonic it and the LPI if poss in citric acid solution. Put a BIT of silicone grease [tube not aerosol type] connect to first stage, quick inflate and all the inside of valve has a nice thin coating of lube. I have done this once every couple of months for 9 years with no prblems. >Ultrasonic it and the LPI if poss in citric acid solution.

I >have done this once every couple of months for 9 years with no prblems. I should have done that last week. Instead I took it into the shop (reg still attached to BC). He asked how old the hose was. I told him 20 years. Three minutes later he was charging me for a new hose. Signaturedillon Linux, it's not just an OS, it's a way of life.

Well, thanks for all the replies. I actually tried using a little bit of silicone grease on a cue-tip and now it connects and disconnects beautifully. >> My low pressure hose to my dry suit is getting quite difficult to remove, >> which is a bit worrying in case I need to disconnect in a hurry.

Also it can be risky when putting on. My dad's colleague was putting on a hose from a cylinder onto an inflatable tent and it didn't connect properly (either he didn't pull it to test or it was too stiff to pull off). Air was turned on and it flew off to smack him squarely in the forehead, creating a small cut and a quick trip to hospital for a check up. Gareth > Also it can be risky when putting on.

Only in the U.K. No one in America would dream of going to a hospital for a small cut on the forehead. It's no wonder you guys lost the Revolution.

Only if the paper is very thick.

Or possibly begin an investigation to link the air hose to a terrorist conspiracy :-) >> "Greg Mossman" wrote > >> [quoted text clipped - 10 lines] >Or possibly begin an investigation to link the air hose to a terrorist >conspiracy :-) Well obiously, it is. Or perhaps you're a terrorist trying to sew discontent amongst the members of these two find, harmonius groups.

It's no wonder you guys lost the Revolution. Thats because we have a free health service. I wouldn't go if I had to pay like you guys. > Do you call 911 if you get a paper cut?

Don't you Brits ever >> take facts like that into consideration? Do you think all accident [quoted text clipped - 3 lines] > > Jason Good point. They're all upside-down there. But here in the U.S., dialing 0 would get you an operator. That was back when there were operators. Today it would likely get you lost in some eternal voicemail damnation of touchtone prompts. Dialing 000 would triple the hell. I'd rather dial 666. After our terrorist attacks of 9/11, I believe they should change the emergency number here to something like 000 or 666, and reserve 911 for the sole purpose of reporting terrorist attacks or potential terrorist attacks or just to report your neighbor if he happens to look Brazilian. >> Which reads 666 if I turn my monitor upside down.

Nah, 666 is not a valid number.....here in the US tho, we consider everything right Greg? so 116 calls are forwarded to 911.
