Product description Overview These plastic grommets and hole plugs form a firewall gasket kit designed to protect electrical wires and cables where they pass through panels and bulkheads. The double sided grommet design cushions and seals both sides of the panel, reducing abrasion and movement that can damage insulation. The kit includes assorted sizes and a plastic ring storage pack for convenient carrying and organized storage. Key benefits Enhanced wire protection: Double sided construction surrounds the wire on both sides of the panel, minimizing chafing, cutting, and vibration wear. Reliable sealing and spacing: Acts as a firewall gasket and hole plug to fill gaps, keep wires centered, and prevent rubbing against sharp edges. Broad compatibility: Flexible sleeve and plug design fits a range of wire and cable diameters, making the kit suitable for different wiring layouts. Easy to store and transport: Plastic ring packaging keeps plugs and grommets organized for quick access on the job or in the workshop. Quick installation: Push in grommets and plugs require minimal tools and can be installed from either side of the panel for fast maintenance or assembly. Product features Material: Durable plastic with enough flexibility to compress into panel holes while resisting tearing from repeated installation. Design: Double sided grommet and wire protection sleeve for full edge coverage and improved longevity of wiring. Sizes: Assorted hole plug sizes included to match common cable diameters and panel hole sizes. Function: Serves as firewall grommet, gasket, and hole plug for wire pass through locations. Packaging: Plastic ring keeps each plug and grommet separated and easy to carry. Performance and compatibility Protects wire insulation from sharp metal edges and vibration. Compatible with common automotive, marine, appliance, and industrial wiring sizes. Works with metal, plastic, and composite panels where a sealed, cushioned pass through is required. Typical applications Automotive firewall and bulkhead wiring: Protect engine bay and cabin wires where they pass through the firewall or inner fender panels. Marine and boat installations: Seal and cushion wiring that passes through hull or console panels to reduce chafe in a wet and vibrating environment. Home and industrial electrical panels: Use in junction boxes, enclosures, and equipment cabinets to protect control and power cables from panel edges. What makes this kit useful The double sided grommet design offers more complete protection than single flange grommets by covering both edges of the hole. Assorted sizes reduce the need for additional parts and allow the same kit to be used across multiple projects. Plastic ring storage simplifies inventory and makes it easy to bring the right grommet to the work site. Contents and usage tips Assorted plastic grommets and hole plugs in multiple diameters. Plastic ring for storage and transport. For results, select the grommet size that compresses snugly into the panel hole and leaves the wire snug within the sleeve to prevent movement. This kit is a practical, easy to install solution for protecting wires at panel pass through points, improving durability and reducing the risk of insulation damage.
