I?ve been searching for a solution for a firewall pass through fitting for wires. I?ve wanted something that gives the ability for the inevitable need to open and close so a wire can be removed or replaced. I have seen the odd looking round ones protruding from the firewall with the fire sleeve and globs of red silicone hanging out. Pulling a wire in/out with a connector on the end of those that are crowded with other wires is difficult without hanging up. Besides having to dig the silicone out is a problem and could cause damage to other wires.
I have designed my own but haven?t made one yet. This is a .020 stainless box with silica seal material braided like a rope such as used in a heat treat oven door. It is rated to 2300 degrees. It is packed into the bottom, then a layer on top of the wires then a clamp held firmly with two bolts. This gasket material is very smooth and forms nicely around various sizes of wire lying next to each other. I have a seam formed around the wire opening so there are no sharp edges.
This is the first design. I plan to make the overall height shorter.
I would like some feed back to this design idea. Fire a way!
