Unique-Bargains 5pcs Black Rubber Grommets 25mm Conduit

Automotive rubber grommet kit

This five-piece set supplies black rubber grommets designed to protect wiring as it passes through drilled holes in body panels. Each grommet guards cables against sharp sheet-metal edges that can abrade insulation over time. The parts are new and intended for automotive electrical work or similar panel-penetration tasks. They arrive as a ready-to-use pack of five identical pieces.

Single-sided 25 mm conduit design

Every grommet measures 20 mm inner diameter by 33 mm outer diameter with a 5.5 mm thickness and weighs approximately 14 g in total for the set. The single-sided profile seats from one face of the panel, so installation does not require access to both sides. Black rubber construction resists weathering and vibration in under-bonnet or chassis locations. The 25 mm conduit sizing matches common automotive wiring passages.

Limited to 20 mm inner diameter

Wires or loom bundles larger than 20 mm cannot pass through these grommets without cutting or stretching the rubber. Panels thicker than 5.5 mm may prevent the flange from seating flush, leaving a gap that reduces sealing. The blind, closed centre must be pierced for each new cable run, so the product is not suited for pre-terminated connectors that cannot be threaded through a small opening. No adhesive or locking hardware is included.
