      Hey guys I'm new and I was hoping you help me out.

      I need a small flame arrestor that will fit in 1.00" (Inner Diameter) metal tube, can anyone tell me where to get one or another way around this problem.

      The spark and flame arrestors in small engine mufflers as a piece of fine stainless steel screen. the sparks and flame hit the screen and quench. A Davies mining lamp used a metal screen around the flame in the lamp and provided the same function.

      I would suggest that you get some brass, copper or stainless steel screen and fabricate a disc of one or more layers that you can fix in the tube. Up to a point it will stop flame and sparks. The way such a design fails is if the screen gets hot enough to start glowing. Then it can ignite any combustible mixture downstream of the screen. In that case you fabricate a stack of copper plates that have gaps between the plates for the flame to enter. Fit this into the metal tube and be ready to cool the outside of the tube to keep the plates from starting to glow. This will quench the flame and keep the downstream mixture from igniting.

      Are you trying to build your own or to shop?
