B-SQUARE HYDRAULIC DENT RAISER

COPPER TOP

[:)] I have a B-SQUARE hydraulic shotgun barrel dent raiser, am looking for the very small o-ring ( .155 ) on the piston. Anyone have these or have a source?


Thanking you in advance for any help you may be able to provide

Sammie, your local auto parts store should have a good selection of o-rings. If you have the old one take it with you. If you don't, take the part it goes on, they can fix you up.

also look in the air conditioner "O" rings. those are usually better quality and in some different sizes than standard O rings.

What dimension is .155, ID, OD, or cross section?

If your doing any smithing, you must have a pair of good dial, or digital calipers. Measure the groove width, and depth. Choose your O-ring accordingly. 25% of the O-ring's height should be above the shaft, and there should be a little to no wiggle room for width. I would use a Viton compound one if I could.

also check the stores that sell paint ball guns

I've found o-rings at Ace Hardware, you might give them a look.

Find a good gasket house in your area. They will usually have all sorts of o'ring sizes available. If they don't have your specific size than they can make you some.

This one might be close to you.

Anyone with more than 3 screwdrivers and 5 wrenches... should have one of these $10 kits under the workbench.[:D]

You will need to know first if it is inch or metric size - they are not the same. Measure the bore size it fits into, then the cross section size of the o-ring (they are a few thousandths oversize to allow for squeeze. Do not expect the folks at a hardware store to find the right one for you.
