No oil/oilless air nailers

1 month 1 week ago #3166 by IATSEtoolguy

Hi guys, I'm new here. Happy to find this forum. I'm the tool specialist for our shop. Needless to say, if it breaks, squeaks or has maintenance schedules, I'm the guy. I take care of a $200,000 inventory. Love my job. Love to tinker.

So here's my question. What do y'all use to lubricate an oil free gun? I have some Senco nailers and staplers that are the oiless type. Of course our carps are often leaving them on the floor in a pile of dust, etc. They get dirty, malfunction, and need a cleaning.

Currently, as with our oiled guns, I'm lubing up O-rings and piston with a light coat of white lithium grease as I rebuild. I'm aware the oil guns dilute this with oil going through them. We do not have a oil drip on our compressor. Just an old Speed Aire regulator/water collector.

As I understand it, the piston ring on the oilless guns is teflon. But even with a teflon pan, one needs some butter to fry an egg. Some guns have aluminum piston chambers. Some have plastic.

When y'all clean/rebuild these oilless guns, what do YOU use as lube during reassembly?

Thanks!

We lube all of the o-rings completely before installing, but do not use any type of lube on the teflon composite ring. You could use a dry silicone spray, but that's about it. Anything else can prematurely degrade the piston ring. These are truly to be oil free nailers.
That's what we do at least!

What lube do you use on the o-rings though? Regular air tool oil or something else.
Thanks for the tip on the teflon ring.

We use oring grease. You can get it at a plumbing supply house or simply ask if they have any of the sample tubes available for free. A tool repair shop should have plenty of these to hand out.
