Value Collection IBNRG-4-BKN Rubber Grommet 50 Pack

Product Description

The VALUE COLLECTION IBNRG-4-BKN is a Buna-N rubber grommet designed to protect wiring, tubing, and cables passing through punched or drilled panel openings. With a 5/8 inch outside diameter, 1/4 inch inside diameter, and 1/4 inch overall thickness, this grommet seats into a 7/16 inch slot diameter opening with a 1/8 inch slot width. The Buna-N compound delivers resistance to oils, fuels, and common shop fluids, making it a practical fit for electrical panels, HVAC equipment cabinets, and sheet metal enclosures. Hardness is rated at 45 to 55 Shore A. Electricians, HVAC technicians, and panel fabricators routinely use grommets of this type when routing low-voltage control wiring or refrigerant sensing lines through metal chassis walls.

This grommet is suited for residential and light commercial applications where wiring or tubing must pass cleanly through a metal panel without chafing or abrasion damage. Typical installation scenarios include electrical junction boxes, HVAC unit control boards, motor housings, and fabricated steel enclosures. The black color blends with standard panel finishes. Each package contains 50 pieces, making it a practical stock item for service vans and shop inventory. The Buna-N material performs reliably in environments with incidental exposure to petroleum-based lubricants and refrigerant oils.

Compatibility

Designed as a standard-fit rubber grommet for metal panel openings requiring a 5/8 inch outside diameter snap-in style grommet in electrical, HVAC, and mechanical enclosure applications.

Installation Notes

De-energize any panel or enclosure before installing or removing grommets near live conductors, in accordance with applicable NEC requirements. Press the grommet firmly into the panel opening until the flange seats flush against both faces of the material. Verify the slot diameter and panel thickness match the grommet dimensions before installation to ensure a secure, rattle-free fit. Sharp burrs on punched openings should be deburred before seating the grommet to prevent premature wear on the Buna-N material.
