Porter Cable Nailer Fix for trigger issues DA250C FN250C

Hey Brain 3👍up. Thank you, my Gun was just out of warranty and did the same thing. Price has gone up for the part on Amazon $23 now. Easy replacement and works great. Thanks Again!!!!

Hi Brian, my porter cable nail gun was working and there were no air leak! The trigger was doing the same thing that your video showed. I watched your video and took you advice. Order one from Amazon! Works great! Thanks for the video and advice!!

Great video, thanks for posting! I’m having the exact problem with my PC nailer. Brought it to a repair shop who estimated $90. and three weeks to fix. It was then that I decided to check YouTube. Should’ve come here first! 🍻

Just wanted to say thank you to Mr. Kanoy - thanks to this video, I was able to repair my gun in about 5 minutes and for about $18. Three pins - two holding the valve, one the trigger, popped it out easily, put the new one in from Amazon, put the trigger back and three pins back in and done. And I'm not the most handy fella -- I had to buy a punch set even (suggested on Amazon with the valve even!), but that is a good investment anyway.

THANK YOU! This is what happened to my Banks 18g Brad nailer. Now I just have to find that valve for it.

Thanks for the help! I ordered the part from Amazon less than 24 hours ago and my nail gun is working like a charm!!! I did lose the little ring that holds the trigger pin in... I could rig something, but think the nailer deserves a new one!! Thanks again... now for that beer...

Nailed It thank you BK, your 9 minute video made my repair much simpler and merely 4 min long

Thanks for this video. Like you I was having the trigger leak, not the piston leak problem and was kind of flabbergasted as to how to fix it. Watching you do this gave me the confidence to order the part from Amazon. 15 mins later, and I have a finish nailer that works like new. My only difference is that when you put the new assembly back in (around 6:40ish) it popped in pretty easily. I needed to use both thumbs and press it back in harder than it looks like you did, until it clicked. Otherwise, I was back in business in no time. You are an internet hero.

I have the same nailer and the same problem. I actually took the trigger valve apart and found there is a little plastic o ring that has destroyed. It looked fine just like yours but once taken apart the problem was obvious. New trigger assembly solved the problem.

Well done! With things falling apart, and springs and assembly doodads shooting out, I probably would have thrown it away and bought a new one, all the while snarling expletive deletives (my technical muttering) then explaining to my wife that it couldn't be repaired. Thanx!!

Watched the video. Ordered the replacement trigger valve from Amazon. Watched video again with new part in my hand. 5 minutes to replace and test. Works great! Thanks.

Thanks! Replacing the valve assembly fixed my nailer.

Thanks for posting the video. I was able to fix my gun with your help!

Great job! Placed an order for a replacement right away. Your comic relief was appreciated too 🤣

You saved me. I thought I broke my brother's gun, and would have to replace it. Thx

this is bc the metal shaft in the center has 2 tiny o rings that most likely disintegrated with use. you can only see them or the grooves if you take that trigger assembly apart. instead of ordering that part, i ordered a whole assortment of orings and hopefully that will fix it as well. but great job on the video!

Thanks for sharing your knowledge. It is very helpful. Now I will repair my nailer. Salutes from El Paso Texas.

Worked like a winner thanks Brian!

As soon as you added the beer as a necessity to complete this project, I subscribed!

Great job!! Thanks for sharing. I’d bought the finish nailer years ago and just got to use it. Worked fine for a dozen nails and the I decided I needed shorter nails. Off to Home D. Got another 5-10 nails in and happy camper I was. The next trigger pull nothing. WTH??!! Checked for a jam. Clear. Pulled up you video. I guess this is the problem. When I pull trigger I hear a hiss from back end. Will order the part and punch set on Amazon. Fortunately I have the beer!!
