Brass Fuel Valve - Restore?

[T. Cotten]

I use polishing compound to seat the surfaces then coat lightly with paraffin wax. Redo yearly. Been working good on 1946 Chief original peacock.

If petroleum-based paraffin works a season, Paul,...

Perhaps bees' wax might resist fuel a little longer.

Just a thought that I cannot follow up upon,

Tried bees wax. Too sticky.

There is a product called EZ Turn that is a lubricant - sealant used in the aircraft and marine industry. Good for high temperature and high octane fuels. Not supposed to gum, crack or dry out. Recommended for tapered plug valves. Sold by Aircraft Spruce a supplier for the aircraft industry.

I have used EZ Turn on all my early Hens, Ex's, and H-D petcocks and it is the only thing I have found that makes them usable. As Jim said, you will have to re-apply it in a year or so, but small price to pay for a reliable genuine petcock that won't leak. Oh yeah, it's not cheap, but they sell a tube that will last most AMCA member's life-time.

I should add that the petcock has to be in good shape, and the taper properly lapped to a respectable dry seal.
