Grommet Assortment Kit

The Painless Wiring Grommet Assortment Kit (Part #71901) is a comprehensive firewall grommet collection designed for custom wiring installations in automotive and powersports applications. This rubber grommet assortment provides multiple inner diameters (0.312 to 1 inch ID) and outer diameters (0.500 to 1.500 inch OD) in a single convenient kit, eliminating the need to source grommets individually across different projects.

Each grommet is manufactured from durable black rubber that resists weathering, UV exposure, and oil contact—critical for firewall applications where wiring passes through metal panels. The range of sizes in this assortment accommodates standard wire gauges from small gauge sensor wires to larger power conductors, with the stepped diameter design sealing gaps while maintaining strain relief around cable bundles. The rubber composition provides both flexibility and compression strength needed to prevent chafing and short circuits where wiring transitions through sheet metal.

This kit is essential for custom wiring projects, engine bay restorations, hot rod builds, and professional automotive harness installation. Technicians and builders appreciate having multiple grommet sizes on hand to avoid project delays caused by missing fasteners. The assortment format ensures compatibility across different wire gauges and firewall hole sizes without excess inventory.

Painless Wiring grommets meet industry standards for automotive electrical applications and are trusted across restoration shops, custom builders, and DIY installations. Whether organizing a complete harness replacement or patching individual penetrations, this assortment delivers the coverage needed for most firewall wiring scenarios.
