What do you think of using a grease zerk? Just push down on the spring loaded ball to relieve pressure. It's small and doesn't need a cap to unscrew. Just don't let anyone grease your forks for you!

I zerk fitting would work great...but is it air tight? You wouldn't want air or oil to come out LOL! A zerk would be better since it is smaller and does anyone know if there is a internal o-ring or some sort of a seal inside the zerk fitting? A zerk fitting is where your grease gun attaches to (for anyone who doesnt know what it is) Later,


Every time I come to this thread someone has thought of a new way to let air out! LOL

I'm not sure if it is airtight or not. I will try to find out. If it is, I would bet that you can find one that is 5mm (I think that is the size) and you would not have to drill & tap. You could simply put a small o-ring onto the zerk.

I would think that if the grease zerk leaked air pressure that would be better yet. Isn't our goal to get air out and keep the oil in? The pressure of the ball against the seat should also keep out water and dirt. This may be the lightest, cheapest, easiest works part yet!

Would the leg fully extended cause a vacum and suck air on a zerk fitting ? ? ?
