Seals-it Split Grommet Seals
Seals-it split grommet seals use a combination of fire-retardant rubber and anodized aluminum bezel, making them the perfect choice for many applications. In race cars, they keep unwanted smoke and fumes from entering the driver's area, while protecting lines from chafing and abrading on rough surfaces. In hot rods and custom car applications, they provide the perfect "finishing touch" to all through-panel installations. Wiring, fuel and oil lines, air and liquid hoses, and all other lines that make up your rod or custom can make an otherwise detailed installation look unfinished. In response to many inquiries concerning how to seal and "dress up" existing hose, wire, cable, etc. we have developed the new "split" Grommet Seal. The unit comes in two half-part sections so that it can be mounted on an existing installation without disturbing anything. Seals-it grommet seals add the well-organized, professional appearance you want throughout your vehicle. Available in standard hole sizes from 1/4 in. thru 1 in. in 1/8 in. increments. Alternate hole sizes are available for any order of 5 pieces or more.
