Porter Cable FN250C 16 ga finish nailer won't fire 

Thanks for posting this. I have the same model I've had for 10 years and mine started doing the exact same thing today. I'm ordering a replacement trigger piston assembly, got nothing to lose trying. Thanks again.

Replaced the trigger and mine works like new. Thanks for showing the total tear down. I popped the three pins, pried out old trigger and snapped new one in in about three minutes. Amazon costs, about $14.00. You saved me around $170.00. Again, thanks for the video.

Thanks Joe! that is exactly what was wrong with my nailer. Glad I found your video!

Thank you for the detailed video, Joe! Fixed it in no time once the part arrived! Cheers!!

Great video. Just exactly what i was looking for. Got mine working and saved me the expense of buying another one. Thanks.

Wanted to say thank you, thank you, thank you for this video as my nail gun was having the exact same issue. replaced the trigger assy and its working like new again.

Thanks much, you helped get my nailer’s trigger back together.

I had the same problem with my nailer. I found those tiny O-rings, put them in and got the nailer work again. Thanks for pinpointing the root cause.

Nice video. I thought I was listening to Anthony Bourdain, may he rest in peace. You have a great voice and should be making bank doing voice overs.

Exactly as u said. I ordered trigger and when I replaced it the old one had no o rings left! Thank you

Thanks for this! The last part of the trigger insert was hard to pull out. I used a Paint Can opener, the small hooked end was able to grab a spot down in there and it popped right out. Looking forward to using this nailer again!

Thank you, Exactly what mine is doing.

Waow.... Thank you sooo much for this vedieo.. Much appreciated

Same gun, same issue. Thanks very much!

My gun was acting up last time I used it. Today I started using it and it failed just like in this video.....Now I know what to look for when I take it apart....Thanks !

Great job and the good way to explain things appreciate the update 🇩🇰🙏👍

Have the same problem with mine. Gonna try the trigger assembly replacement. Thanks!

Thanks for the video! I've been having the exact same issue, I'll get the part and hopefully that will fix it!

Saved me some time! Thank you 🙏

I was building a doghouse for my corgi and my exact same finish PC nailer had issues just like urs. Hoping to just replace the o rings and call it a day. Thanks! Liked and Subbed!!

Glad someone made the trigger replacement parts that original manufacturer didn’t support their products anymore by providing spare parts

Good video. I had the same problem... and I noticed there were never real "O-rings" in there originally to begin with, it was just a semi-stiff seal made of grease/glue!!! No wonder it looked like they disintegrated. Planned obsolesce caught red handed! LOL. Needless to say I will not be buying Porter Cable anymore. I was looking for an excuse to get a Milwaukee cordless....

Lol... I haven't dug that deeply into mine, but it's is doing the same exact thing. I rightly assumed ot had something to do with the trigger. I'll order the part and see if it will fix the gun. Thanks!

I could have told you from the start that its the trigger valve. I fiddled with mine a couple years ago and learned the hard way

Great video. Thanks for sharing

Thank you

this is a common issue many porter cable fn250c nailgun failures guns Look brand new still , i have same one , obviously manufacture is using very sinister cheap parts assembly, trigger seals etc just getting money $$ from customers .

first 20 seconds of the vid i WAS TELLING YOU IT WAS THE TRIGGER VALVE

Let me guess you charge the customer 4 days worth of Labor to fix a $40 stapler good video anyway though I bet you're glad you made it so you can put it back together and see where everything goes

are these good nailers also what is the difference in the different modles in the 250SB and 250C 250B

Hopefully you’ll tear into the porter cable pancake compressor. Mine leaks when it hits around 100 psi in tank and won’t shut off due to it.

What's the serial number so I can order my trigger from my through Amazon

I have the same problem (DEWALT d51257 is identical mechanically). Whatever is left in mine looks like rings made out of grease. Instead of buying a new assembly, has anyone found the size of the replacement rings?

Did you fix it, or u bought anew one? I did watch it till end good job.

Have the same problem with my air nailer. Porter cable wants 48.00. What is the part number for the trigger assembly from Amazon

Your voice is really familiar

same problem with mine too. so maybe those PC pneumatic gun are totally junk.

you didn't oil the top gasket. LOL

HF spend $100 and you save 8 hours of your life

It was shooting 2 nails because it is a 16ga nailer and I’ll bet you were shooting 18ga nails

Most frustrating and unreliable tool I've owned. Appreciate your video, but the gun isn't worth the effort. Had mine for years, and even using their nails, continues to multi-fire and jam. Won't even give it away. It's trash material.

Thanks for your information,.
