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.

Worked great

by: 11/21/2023

Bought it. Never arrived. Package says it's in there but nothing. Complete rip off.


I had a great experience. Got the product with no problems.


The only problem I had was having to buy a 11/16" drill bit. All the parts worked great!

Still doing fine


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.


I ordered a couple of fenders and other small hardware for a camp trailer I’m building. I bought enough to qualify for free shipping. The order went through very quickly and the package arrived two days earlier than promised! All was correct with the order. No damage. Great service.


Got everything I ordered quickly. Installed everything and referred to some of the trailer install videos, which were a big help. Towed my camper for the first time the past weekend!


It protects the wires very well. I added some silicone sealant to keep the critters out


Excellent reaction time in getting products processed and shipped.


A way to protect wiring from shorting. Easier to use than a rubber grommet.


Huge selection, fair prices, easy to navigate web page and free delivery. Very pleased!

  • Parts Needed To Install Tekonsha Prodigy P3 90195 In 1994 Chevrolet Silverado W/ Factory 7-way
    Since your 1994 Chevrolet Silverado Pickup has the factory 7 way connector wiring you will have a blue and orange wire located underneath the brake booster. The factory orange wire will need to be connected to the 1 o'clock pin of your 7-way connector and then will get installed onto a fused stud. The factory blue wire will need to be routed inside of the cab of the truck through a bushing like # SWC8057 to connect to the Tekonsha Prodigy P3 # 90195. You will need to get the # 5506...

    For your 2015 Honda CR-V, I recommend the Tow Ready Custom Fit Vehicle Wiring # 118561.

  • How To Install a 7-Way on a 1996 Chevrolet Suburban
    The blue brake output and orange 12 volt power wires are already ran on your 1996 Chevrolet Suburban however, as you suspected they are not yet connected. The rearmost point of the wires near the trailer hitch will need to be connected to the 7-way. Once the rearmost point of the wires are secured to the 7-way you will then need to connect the forwardmost point of the wires to the brake controller and 12 volt power. The forwardmost wires will end in a gray connector under the brake booster....

  • 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.

  • Which Size Circuit Breaker Is Needed For Tekonsha Primus IQ In 1996 Chevrolet Suburban
    Thanks for the kind words! Starting with the # ETBC7, you are right on that you will connect the factory run blue and orange wires to the 7-way connector, and will connect them to the studs on the fuse box of your 1996 Chevrolet Suburban using the # DW05705-1 and # 185917. The 30 amp fused post will be fine to connect the orange 12v power wire to. You will need to add a grommet to the firewall to get the factory blue brake output wire to the trailer brake controller.
