      Compared to electric and battery-powered tools, pneumatic nailers are supereasy to repair. In this episode, host Patrick McCombe goes step-by-step through the process of replacing the trigger valve and all the O-rings and seals inside a Bostitch N80 framing nailer. The repair parts are readily available, and the whole process takes about 15 minutes using basic tools.

      When a pneumatic nailer breaks, it doesn’t make a lot of sense trying to isolate the individual part that is broken. The rebuild kit includes all of the wear parts, so it makes sense just to replace them all. Although in the video Patrick is working on a Bostitch nailer, the internal parts and seals are basically the same for every brand of framing nailer. In addition, the repair process for roofing and finish nailers is nearly the same.

        Man if only this had come out in September. My nailer died and I had no idea what was wrong and didn't have the time to figure it out so I just bought a new one. Now I can repair the old one and keep it as a backup.

        You got lucky with that kit. My brad nailer died a year ago. I bought the kit, took apart the nailer, and found that the kit had a few parts that didn't match my nailer and was missing some including the one that I needed. I double-checked and am sure it was the right kit. I was able to kludge it to finish up what I was doing, but I expect it will die for good one of these days. Fortunately I have a newer one as a backup.

        It's THAT easy! Mine failed last year and I mentioned it to the guys at the lumber desk. They had the kit in stock and did the job for free!
