GROMMET: (P/N 81-4) - New Surplus

The 81-4 is a rubber grommet for routing wires, cables, and tubing through panel and bulkhead openings. This elastomeric seal protects lines from chafing and abrasion where they pass through structural penetrations in aircraft fuselage and systems. Installed in properly sized holes, the grommet isolates electrical and fluid lines while preventing edge damage during vibration and movement.

Conforms to AN931 and MS35489 standards for material composition and dimensions. Verify hole size and grommet specifications against your aircraft's maintenance manual or Illustrated Parts Catalog before installation.
