Video Transcript for Spectro Snap Bushing Grommet Review

Today we're going to review and install the Spectro Snap Bushing, part number SWC8055. Note, the snap bushing is available in two sizes: the 7/16 inside diameter and a 9/16 inside diameter, part number SWC8057. Here's what our Spectro snap bushing looks like. This is a nylon bushing that will help protect our wiring as it passes through our pre-drilled hole. Typically that hole is drilled into sheet metal like a firewall. The raw edges of the metal can chafe or dig into the wiring or even an air line, and the snap bushing will protect it. Once the snap bushing is slid through your pre-drilled hole, the locks here will help hold it in place and the face of the grommet will be on the other side of the firewall, so we'll have part of the grommet on each side holding it in position. When drilling it out, you're going to open it up to approximately a 9/16 hole.

That makes the inside diameter 7/16 and the outside overall is 21/32. The grommet itself is 13/32 thick. Our grommet is typically used in areas where there's not a lot of heat, but it will hold up to approximately 257 degrees Fahrenheit. Now with the hole drilled out, we'll go ahead and take our snap bushing and install it. Put it in the hole, push it into place, and it locks into position. We're now ready to route our wiring, air line, or whatever you need to route through the protected hole.

There you have it for the Spectro Snap Bushing, part number SWC8055.

It's a good one. This prevents the wire from scraping the edge of the metal hole causing wire breakage. The only thing is the drilled hole requires a drill bit larger than 1/2", otherwise you have to expand the hole using the sides of the bit. It took me a while with trial and error. I have a good collection of drill bits but unfortunately the largest doesn't go beyond 1/2", and I didn't realize that until trying to fit the grommet inside the hole. By that time, I didn't feel like to go out to just get the right sized drill bit. Just wish they make a grommet that fits the 1/2" drill hole. It's a great product. 450592

  • How to Route Wiring Through Firewall When Installing Brake Controller on 2014 Ford Escape
  • Your best bet is always going to be using an existing opening. If you can find an existing grommet where a factory wiring harness passes through the firewall into the passenger cabin, you can use a sharp knife to carefully poke a slit in the rubber or plastic grommet to pass the wire through. If you cannot find anything, you'll need to drill your own hole, being extremely careful to make sure that there's not anything on the other side of where you're drilling that would be damaged....
