Bumper Boy O Rings

[Keith Stroyan]

a #10 at Lowes is the same size as a #10 at Home Depot.

But it uses #11.

(At least the older ones do.)

I don't seem to have problems with my bumper boys like others have stated. ...

I have replaced several servos and replaced the batteries. I do use graphite in the releases when I re-charge.

I launched around 1500 bumpers this summer and over 10k since I bought them. I don't see a need to replace them yet.

That's fine. I just mean that no matter where you buy the O'Ring the size, whether it is a #10 or a #11 they will be the same. A # 11 here is the exact same as a #11 any where else in your city.

i use BAG BALM on the orings and also on the electrical connections, keeps the orings sliperry and the connections dry and corrosion free. also good for skin, and other uses stated on can.

I cant find any spray graphite like they show on the bb videos....regular powdered works the same right? Forgive my ignorance on the subject...thanks in advance.

Silicon spray works well and we spray the shafts before every use.

I use silicon spray on the shafts too but don't spray it in the tubes.

That's what he and she said.

I think they last longer and stay in place if you grease them.

I spray Silicone up the bumper's butte from time to time – makes the bumpers slide on easier.

Harbor freight. No since paying extra at lowes or home depot when you are gonna replace them anyways. save a dollar or to and go to harbor freight.
