Porter cable round head nail framing nailer
The seal that was recommended did the job. It arrived in perfect condition. So I was able to get my nailer back on line for a very reasonable price and she is good as new. Thanks Ereplacement parts

Repair was easy and cost effective. All I did was watch the video first to see if I wanted to tackle the project. When it was over discovered there really isn\'t a lot of parts inside to keep me from trying it. So, I disassembled the nailer and found the source- broken piston bumper. I could see all kinds of plastic pieces scattered throu
... Read moreghout the internal workings of the gun. After a good cleaning and a check of all the o-rings, the top portion of the nailer would have to be replaced. Next, I ordered the parts from the website which was simple and easy- in fact I also found a part to my Porter Cable sander as well. After a few short days the parts arrived and I put the gun back together, plugged it into the compressor and tried it out. \"P-ka,\" the nailer was once again making that sweet sound that my wife can\'t stand.
Now if I had to buy the complete overhaul kit I\'m not too sure I would have fixed the nailer. Reason being, the big box stores are always having a sale and a new one could be found for 30-50 dollars more with a one year warranty. Unless, I already had an abundance of nails that were specific to the old nailer then I would fix the old one.
Good Luck with your project and may the force be with you!
