Question about Senco Air Tools & Compressors

1 Answer

I have a Senco Palm nailer. It works but there is a small air leak all the time. I am guessing it is one of the o-rings but not sure which one.

    At the same time I posted this I left both voice message and email question to Senco direct. They emailed me a link to Danair, Inc who apparently is the manufacturer. Their site had a troubleshooting list which I downloaded. For the type of leak I had they advised to change gasket, screws, or valve seat. The valve seat did the trick. The tool is over ten years old but not used on more than 50 nails or so total.I

There are 3 reasons an air leak can take place on this tool.

1) Most likely your o-rings are worn.
2) If the leak is coming from between the head cap and the body, at the gasket. The gasket may need to be replaced.
3) Very unlikely, The body is worn where the o-rings contact the housing.

If it is not a gasket problem, open the tool and look at each o-ring. If any are worn, or have a small inconsistency replace it.

Here is a breakdown of Senco's current Palm Nailer.

I have a senco coil roof nailer that all of a sudden is leaking air big time and will not coil and fire nails. What parts do I need to replace.


depends on where the air is leaking from. If you go to senco.com and type in your model number you can look at a breakdown and they will list the rebuild kits specific to the leakage, they make an upper o ring kit and a lower kit for this problem. Let me know if you need more assistance or where the air is leaking along with the model number and I will find a number for the rebuild kit. Also the senco kits have detailed instructions on how to install them.

Senco sns40 stapler replaced all o rings still leaks air. Even seals in trigger assembly. Leaks out the exhaust port.


Air leaking thru exhaust on sns40 gun is indication of pinhole in rubber diaphragm of firing valve (part #BA0120). This gun is oil-less type and will develope leaks if oil is used. Most likely need to replace firing valve to restore to working order. Parts are at www.toolpartsdirest.com. Good luck

Finish Pro 32 is Leaking air out of the exhaust cap


You have worn or broked o-rings/seals inside the gun. The Finish Pro 32 is one of Senco's older guns and they no longer offer a repair kit for this gun. You have to go to a site like www.senco.com or www.ereplacementparts.com, find a breakdown of your gun and order each part you need. If you are going to rebuild the gun order all the o-rings/seals (Senco parts that start with LB) and any other parts that may be damaged like the piston stop, springs, etc. Lubricate the o-rings with light grease as you put them in and make sure to oil the gun regularly when you are using it to make your work last.

Air nailer vnot operating. blowing air from top close to handle


Your nailer has worn or broken o-rings in the top end. You need a rebuild kit (Senco part number YK0360) to get your gun going again. They are available through most online, after market parts stores. When you get it, remove and replace each seal and o-ring one at a time so you get them all back in their proper place and use all of the grease to lube the o-rings. Use all of the parts in the kit, if one o-ring or seal is damaged the others are not far from failing.

My senco air stapler sns50 is blowing air out the top what is wrong with it


You have worn or broken seals/o-rings inside your gun. You need Senco repair kit #YK0375 to fix it. Use all of the parts in the kit and replace each ring one at a time to make sure they go back in the right place. Lube them well with the grease provided in the kit.

SENCO Framing nailer suddenly decided not to fire. Air escapes from top of gun when trigger is pulled


You have some worn/broken o-rings inside the gun. You need Senco repair kit #YK0360 to fix it. Fairly easy to replace the o-rings, just be sure to put lots of lube on the rings as you put it back together.

Senco Finishpro18 just stopped shooting nails. Took it apart put it together. Shoots a couple of nails then stops. Press the nailer against the target pull the trigger and air comes out of the handle.


I just had the same problem with mine. Exact same symptoms. My guess is that your gun hasn't been used in a while.

I called Senco and they recommended removing the top cap, removing all o-rings (one at a time) gently stretch them, put a small amount of lithium grease in the o-ring track, and replace the o-rings. This fixed my problem and I hope it fixes yours!

Senco has awesome tech support for their tools. I will not buy another brand because of their support. 800-543-4506

I have some air nailers and staplers that have some leaks and aren't working properly. I would like to try rebuilding them, they are bostitch, paslode, and senco. I have found the rebuild kits for trigger...


The kits for the senco guns, have all the o-rings and seals needed to stop most leaks, no hard parts. You have to replace all of them, no oil is needed, but it needs to be clean, some have little tubes of grease for the o-rings. I'm sure the other guns are the same way. Some of them will give you a fit. I had a senco sfn1, totally rebuilt, still leaked, tried it again, still leaked, called senco, they said send it to us, they fixed it for free, but never said what the problem was. Some times the triggers go and you end up building the whole gun for nothing, and the trigger still leaks, they are the toughest to spot. I have seen a lot of complaints about paslode. We tried them all in our shop, and the senco was/is the best, So we fazed out all the other guns and kept the senco, so all the nails were from 1 dealer, all the parts, we weren't looking all over town for a box of staples.

Audiable air leak within body of Senco 702 xp. You can hear the air leaking and of course, it won't drive nails. Thanks, for any help, Jeff


get a rebuilding kit. the kit will have all you need for overhauling your gun. a blown O ring on the piston is the most common cause of air leaking.

My senco frame pro 650 has an air leak and is evident from the exaust port when sitting idle. Is there a gasket kit available? How do I diagnos where the leak is originating? Thanks


Its not gaskets it is ''o'' rings its not always that apparent with orings so you order in a oring kit and replace all orings pay attention with your triger orings as they are very small i suggest you get a white board and lay all components out in order of removal they are pretty staight forward in there no springs or nastey supprises Oring kit normally has exploded diagram of gun and how it goes together
