Fits perfect on craftsmen 18G nail gun
My craftsmen 18G nail gun was letting air from top air vent continuously. I opened it up just to find the black valve was broken into many pieces. I replaced it with this one and now it works. Thanks!

Repair of Bostitch nail gun SB-1850BN
Received the replacement part quickly and in good condition. The new head valve was a perfect fit to the OEM part that was broken with age causing air to leak from exhaust port and the gun would not fire. Very easy repair and the nail gun works like new again.

Perfect replacement
This is the perfect replacement for that old original black rubber deteriorated head valve in your nailer. It does not come with the valve o-ring, so you may pick that up too. Works great!

easy
My nail gun uses this little plastic part to hold a strong spring. As you would expect, over time the plastic failed. The new part is under 4 screws and fit perfectly. I re-used the "o" rings from the broken part. Easy!

Before I attempted to look for parts I completely disassembled the air tool (Craftsman Brad Nail Gun) to look for a failed part or seal. It helps to have the available parts sheet that illustrates the assembly, I would highly recommend that you have that before disassembly/assembly. Also make sure you clean the inside of the tool after it
... Read mores disassembled. Compressed air has moisture and over the years with use grime builds up inside the tool so make sure to take the time to clean it. The only questionable part I saw that could cause the air leak was the head valve. Its made of plastic and one edge was brittle and I saw a lot of cracks. My intention was to only replace all the seals, but once I went on-line to look for the seal kits I discovered they weren\'t available anymore. The repair tips on the website gave me the confidence that what I was ordering was going to fix my problem. I reassembled the nail gun with the new head valve and I was pleasantly surprised when the gun operated like it should. eReplacementParts saved me from tossing my tool in the scrap bin.
Disassemble the main cylinder and inspect for wear or broken parts. I found the o-ring groove on the head valve piston broken and very brittle. Original was made of a black material. The replacement is made of a white nylon looking material. Assembled all parts with new o-rings and lubrication. One of the easiest machines I\'ve ever
... Read moreworked on. It is now working like new and if it ever has a similar problem, I\'ll know where to go for parts. The original o-rings in mine didn\'t show any damage or much wear, but I felt it was better to replace them since the machine is several years old.
