Replacing Air Regulator On Bostitch Pancake Compressor
Recently the air regulator on my Bostitch pancake compressor broke off when the compressor fell over in the back of my truck. Actually the dial mechanism snapped off when the compressor tipped over as I went around a sharp bend in the road. The dial contained a small spring and thin aluminum housing that easily broke off. If this has happened to you don’t worry as it’s very easy to replace and fix.
Remove Old Mini Air Regulator
In the photo above you can see the old regulator and hose connection highlighted in the red box. The red dial and spring were contained in the round white circular area in the bottom right hand side of the rectangle. You’ll need to remove the hose connection (quick connect) along with the old regulator. The regulator is typically the second pressure gauge away from the compressor and closest to the hose connections. Be sure to save the quick connect hose connection to re-install later.
Purchase New Air Regulator
There are quite a few air regulators on the market for all different compressor sizes. It’s very important to get an air regulator that’s properly sized and rated for the compressor that you have. In my case I purchased a regulator that’s good for 225 psi (normal operating on this model is 2 to 125 psi) with 1/4 inch threads.
Install New Regulator
Installation of the new regulator is very easy and only requires an adjustable wrench. Simply thread the new regulator onto the output fitting (use teflon tape to ensure a tight fit). Once the new regulator is on then install the pressure gauge and re-install the old quick connection for the air hose.
Finally plug the compressor back in, let it fill with air pressure and test the new regulator. This simple repair took about 10 minutes to complete and the compressor runs just as good as it did before it broke.
