What grease should I use to reduce seepage from loading tap leak?

[andrewM]

I have used Nyogel 767 on my Webley Ospreys for several years and would never use anything else now. I bought a tube of it (it wasn't cheap) after I realized that Rocol had ceased manufacture of Kilopoise grease, which would have been my first choice - and it was very pricey as well.

It's difficult to describe how effective this grease is in this role, you have to try it yourself to understand that everything else is basically a waste of time. Buy some, if you're a tap loader fan you will never regret it.

Thanks for that Bill. Do you mean Nyogel 767A? I looked it up and it says it is a synthetic, silica based grease: "A silica thickened, heavy viscosity, synthetic hydrocarbon grease intended for mechanical and electromechanical components that require a heavy level of damping. Used to reduce free motion and to quiet operating noise of loosely-fitting components."

Quite expensive, as you say, with a small tube costing £35 but I have not looked more thoroughly for competing prices.

Hi Andrew,

Yup, 767a. It seems expensive but specialist lubricants are, in industry nobody would blink at that. I bought a tube which will last my lifetime, and have never regretted it. When you think of what you spend on other aspects of the sport it's a pittance really.

Webley Ospreys are my go-to guns, they shoot fantastically well and it's possible that without this grease I would have moved on from them years ago.

As a side note, I do not get hung up on tap loaders sealing perfectly. On my guns some seal much better than others but it makes little difference to how well they shoot. A fluid mechanics expert could no doubt explain that better to us, but I suspect that air under such sudden compression cannot easily escape through tiny leaks.

Some enterprising soul is selling 1g pots of Nyogel 767a for £5...

Doh!

I missed that little nugget of information earlier in the thread.
