This is a genuine Bostitch replacement part, it is sold individually. The purpose of the AB-9051116 Pressure Reducer is to control the amount of air pressure coming out of the compressor tank. This is helpful when inflating items to specified pressure. Also some pneumatic tools use different air pressure specifications to make them operate properly.

Justy Like New
The regulator portion of this assembly is known for failure. I unscrewed the regulator from the 'T' pipe assembly, used it to replace my defective part, and everything worked just like new. Easy fix.

The pressure regular failed.the repair was not difficult. Remove the existing parts that are on the failed regulator. The one thing you need to do is hold the housing it threads into.

Removing the old switch and reducer was the hardest part. Everything was really tight and I had to be very careful in not stripping or breaking any fittings or connections. Take note as to how the switched is wired. Two 3-wire harnesses are colored coded the same. Be sure to install the correct harness to the proper side of the switch
... Read more. Had to replace one electrical connection due to over heating of several years of use. That\'s why I had to do this repair. Crimped on a new lug and connected. After tightening all connections and fittings and double checking the wiring, I turned the compressor on and whamo, it ran. Shut off at the predetermined setting and came back on after I opened the drain to let air out. $50 fix and I have a new compressor.

4.Removed quick connect for air supply while using a back up pipe wrench.
5.Remove pressure regulator gauge with a 7/16\' open end wrench. Proceed cautiously not to damage gauge.
6. Remove defective pressure regulator & nipple with a adjustable wrench while using a back up pipe wrench on the positive compressor side of the pump. This is very soft metal so be smart and don\'t force anything to move.
7. Clean area around compressor side of nipple and make sure that no debris falls inside of open fittings.
8.Use threaded pipe tape to on new replacement fitting per normal pipe fitting specs.
9. Gently reapply the pipe nipple into the compressor positive side were the old part was removed from.
10.Possition fitting to make sure that it is not over tightened and is inline with how the replace part was positioned prior to removing it... This has to be correctly installed to make sure that all of the plastic and gauges are in place to allow the plastic covers to fit correctly.
11.Reapply quick connection fitting and make sure to use the threaded pipe tape on this fitting too.
12. Leak test the fittings that replace by plugging in the cord to electric and allowing the compressor to pressure up to 20 psi and turning it off .. Unplug electric supply cord from the compressor and use test solution or some dish washing liquid... Ten to 15 minutes should be along enough dwell time
13. After the leak test is successful release the air pressure stored in the tank and start the reassembly of the plastic cover...
14. Plug the compressor into the electric source, turn it on and monitor the pressure as it build up in ten PSI increments to make sure that everything is operating correctly before leaving it unattended...
Good luck with your replacement project! This replacement may not be 100% per the book but it worked for me.... The right tools for the job do make the difference...
The factory valve is installed with epoxy on the threads. Use the torch to heat the old valve until the epoxy releases. Use standard thread tape to seal the new unit.
