This is an authentic manufacturer-sourced part which is specially designed for use with Porter Cable nailers. It helps to provide an air-tight seal between connected components. Unfortunately, over time it may wear out and get damaged eventually requiring a replacement. Make sure to refer to the owner's manual for your model to ensure the proper repair procedure. Note, this high-quality O-ring is made of durable rubber and is sold individually. A Hex key also is known as an Allen wrench to take the housing apart when replacing this component.
Removed top from tool. Cleaned out fragments of old piston stop which was completely destroyed. Replaced with new piston stop, seal and o rings. Replaced top. I had found detailed instructions on You Tube.
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!
1. Disassembled the nail gun using the video from this web site.
2. Cleaned all the parts and inspected them for any damage.
3. Lubed all the parts and reassembled the nail gun.
4. Before loading any nails I dry fired the nail a few times.
5. I then loaded 3 1/2 nails and tested the gun, it worked as good as new.
