DIY Co2 Pressure Release Valve for Home-Built Nerf and Air Guns. Are you tired of dealing with malfunctioning or explosive Co2 pressure release valves on your homemade Nerf guns or airsoft rifles? Look no further! This tutorial will guide you through creating a reliable and easy-to-install Co2 pressure release valve that's perfect for your next project. Materials needed: - 1/4" NPT brass tube - Brass fitting (1/4" NPT male x 1/8" NPT female) - Copper tubing (1/4" OD, 1/16" wall thickness) - Aluminum or PVC pipe end cap - Rubber grommet (1/2" ID, 3/8" OD) Step 1: Cut the brass tube to length. Use a tubing cutter or hacksaw to cut the brass tube to your desired length. Make sure it's long enough to reach from the Co2 tank valve to the air gun barrel. Step 2: Assemble the valve body. Slide one end of the copper tubing into the brass fitting, making sure it's seated properly. Then, slide the other end of the copper tubing through the aluminum or PVC pipe end cap and secure it with a small amount of Teflon tape. Step 3: Install the Co2 tank valve. Attach the brass tube to the Co2 tank valve using the brass fitting. Make sure it's securely attached to prevent any leaks. Step 4: Install the air gun barrel. Slide the copper tubing into the air gun barrel, making sure it's seated properly. Then, attach the rubber grommet to the end of the copper tubing and secure it with a small amount of Teflon tape. Tips and Variations: - Use a pressure gauge to monitor the Co2 pressure and adjust as needed. - Add a regulator to control the Co2 pressure and prevent over-pressurization. - Use a longer or shorter brass tube depending on your specific project requirements.
