TRRG30 – Textron Aviation OEM Rubber Grommet
Available now on the Airparts.aero Marketplace.
Overview
The Textron Aviation TRRG30 is a genuine OEM rubber grommet, a flight-critical component engineered for the installation of vent tube elbows on the main ship and emergency power batteries used in various Cessna Citation and Beechcraft King Air aircraft. This is not a standard hardware grommet; it is a precision-molded seal fabricated from a specialized elastomer, designed to provide a secure, chafe-free, and chemically-resistant pass-through for the battery vent system. Its function is critical for maintaining the integrity of the battery case and ensuring the safe venting of battery gases. This part is the Textron-specified equivalent of the Meggitt RG30 grommet.
Key Features
- Chemical-Resistant Elastomer: Manufactured from a high-grade, durable rubber compound specifically formulated to resist degradation from battery electrolytes (such as potassium hydroxide in Ni-Cad batteries or sulfuric acid in lead-acid batteries) and other harsh aviation fluids.
- Vibration Damping & Chafe Protection: Creates a cushioned, protective barrier between the hard plastic vent tube elbow and the battery case. This prevents vibration-induced chafing and wear, which could otherwise compromise the battery housing over time.
- Positive Environmental Seal: Designed with precise dimensions to create a tight, positive seal in the battery case's vent port. This prevents moisture, dirt, and contaminants from entering the battery box while ensuring explosive or corrosive vent gases are properly directed overboard.
- Genuine OEM Specification: As a genuine part specified by Textron Aviation, it guarantees the correct material properties, durometer (hardness), and dimensional tolerances required for a safe and airworthy installation on certified aircraft batteries.
- Essential for Battery Safety: A mandatory inspection and replacement item during battery servicing or whenever the vent tube elbow is removed, ensuring the continued safety and reliability of the aircraft's primary or emergency battery installation.

- Verification: Always consult the specific aircraft's Illustrated Parts Catalog (IPC) or the battery's Component Maintenance Manual (CMM) for final verification.
Applications
The TRRG30 grommet has a singular but flight-critical application:
- Aircraft Battery Venting System: Provides the interface between the battery box and the external vent tube elbow. This system safely vents any gases (such as hydrogen and oxygen) produced during the battery's charge/discharge cycles to the outside of the aircraft, preventing a hazardous buildup within a confined space.
Why Choose TRRG30?
The proper venting of a large aircraft battery is a critical safety function. A failed or missing grommet can lead to chafing damage to the battery case and vent elbow, potentially causing a leak of corrosive electrolytes or a failure of the venting system, which can create an explosive atmosphere. Using a genuine Textron Aviation TRRG30 grommet ensures that the material is compatible with the battery chemistry and that the fit is precise enough to provide a durable, long-lasting seal. For a component so integral to the safety of a high-value battery system, there is no substitute for certified, genuine OEM parts.

The TRRG30 grommet serves as a critical mechanical and environmental seal. Mechanically, it isolates the vent elbow from the battery case, preventing the direct transmission of high-frequency vibration and absorbing shock loads, which protects both components from fatigue. Environmentally, it creates a barrier that prevents moisture and contaminants from tracking along the elbow into the battery box, which could lead to shorting or corrosion. The material's specific durometer is engineered to provide enough clamping force on the elbow to prevent it from vibrating loose, while still allowing for intentional removal by maintenance personnel without requiring excessive force that could damage the battery case.
Note: This component should be inspected for pliability, cracking, or swelling at every battery service interval. It must be replaced if any signs of degradation are present or whenever the vent tube elbow is removed and reinstalled. Always refer to the specific battery's Component Maintenance Manual (CMM) for proper installation procedures.
