This is my new part. Not sure if there should be an O Ring on the upper part of the plunger. If so I don't have one.

So does the rubber O Ring go on the upper part of the plunger that is grooved for the O Ring?
the piston driver i am replacing has the ring, piston attached. I was under impression that the piston driver i ordered would have the ring attached. so much for assuming. anyway, can i remove the original ring and place it on the new piston driver? thanks

Hi vtjohn,
I believe that uses a teflon ring in a plastic cylinder and as long as the cylinder and ring look good it should be fine.Be sure not to put grease or oil around the ring as if I remember right that tool is an oil free tool and any oil that gets around that ring or cylinder will attract dust and will act like a lapping compound prematurely wearing the cylinder and ring out. Hope that helps.good luck.

Question: Nail Feed

I am having trouble with the feed not feeding the 2nd nail to be driven. The magazine shows signs of wear near the driver end of the magazine on the most used size of nail on the slide. Less used nail sizes shoot okay.
