Transducer O Rings - lubrication

[RestlessL]

What should I use to lubricate the O Rings of new transducers (Airmar and Echopilot) ?

[sailorman]

silicone grease / spray

 

[FlorealIII]

I use winch grease

 

[machurley22]

Teflon grease. This one could go on all night. /forums/images/graemlins/smile.gif

K Y ?? /forums/images/graemlins/smile.gif Well surely it must have another use .Hasn't it ??

 

[NorthUp]

fairy liquid(mild green)

 

[steve28]

funny, diffrent answer from each so i will double up on the silicone grease, works really well on the unscrewable porthole lids in dinghys etc, same o-ring idea.

Yes!....Spittle, Washing Up Liquid and KY etc work….BUT! I was always informed, and have used for decades silicon grease with anything rubber. Anything other than Silicon could break down the rubber seal over time. Ask any diver who maintains their rubber equipment.
Cant say about Teflon though.

 

[OGITD]

There is also (only discovered this 08) some specific type of grease used on rubber based impellers, has all the properties + a little more than silicon.
PM if you require details (its down the garden in the shed) or speak with your local Outboard service centre.

 

[Scotty_Tradewind]

I would have thought you needed both a lubricant and a sealant, so the silicon grease would have been better than a mere lubricant that gradually got washed away?

 

[Ruffles]

I always use vaseline on o rings. Doesn't seem to do any harm. Am I wrong?

 

[John100156]

Ruffles has it!

Save all your expensive greases and use KY Jelly sparingly, running-out of that could be most frustrating!

Airmar themselves recommend:

"Inspect the O-rings (replace if necessary) and lubricate them with the silicone lubricant supplied or petroleum jelly (Vaseline®)"

Would be amazed if they were rubber, and very worried about my car engine if o-rings couldn't tolerate oil..... /forums/images/graemlins/confused.gif

Thank you, all. I will go with the silicon grease option.

And, pvb, KY is good for filling the space between in-hull echo sounders and the hull /forums/images/graemlins/wink.gif

I know it's an old thread, but just came across this

"Water-based lubricant (such as K-Y® jelly)"

Not having read every word I'm not sure what 'some installations'refers to. But for the O-ring on the transducer an insoluble lubricant is required, for which they clearly state silicone grease.

My brother-in-law uses a light smear of glycerine on the door seals of his classic cars.

Vaseline works well.
