In this how-to video, you will learn how to maintain a Tippman A-5 Power Tube and Valve. First, pull the valve out of the power tube. Grab the pin with a pair of pliers and give it a firm yank. Next, remove the o-ring and set it aside. Remove the other o-ring off the back. A washer, spring, and plunger will fall out. Remove the other o-ring and valve seat with the tool shown. Now, you can oil the o-rings back up and re-assemble the power tube and valve. Follow the above steps in the reverse order, except remember to lube the o-rings before re-installing. Viewing this video will show you how easy it is to maintain your Tippman A-5 power tube and valve.
