I am trying to make a CO2 air gun and was wondering if jb weld can hold the pressure from the 12g CO2 cartridge in this set up with a CO2 bike pump connected to a valve that can wothstand the pressure
Where is the JB Weld? Use metal threaded fittings with thread tape to help seal the joints. Just like you would hook things up at the output of an air compressor...shift55 said:
Yes, JB Weld has been tested and proven to withstand pressures up to 5,000 psi. However, the strength of the bond will also depend on proper application and curing time.
The curing time for JB Weld is dependent on the temperature and humidity. In general, it takes 24 hours to cure at room temperature (72°F/22°C) and 15-24 hours at 90°F (32°C). It can take up to 4-6 hours to reach its full strength.
JB Weld can be used to repair most types of CO2 air guns, but it is important to check the materials of the gun and ensure they are compatible with JB Weld. It is not recommended for use on plastic or rubber parts.
Yes, it is recommended to clean and roughen the surface before applying JB Weld. Mix equal parts of the two components and apply a thin layer to both surfaces. Press the surfaces together and let it cure for the recommended time.
While JB Weld can provide a strong bond, it may not be a permanent solution for a CO2 air gun. The high pressures and vibrations from use can eventually cause the bond to weaken. It is best to use JB Weld as a temporary fix and have a professional repair or replace the gun if possible.
