RG30 - Meggitt RG30 Rubber Grommet

RG30 – Meggitt RG30 Rubber Grommet

Available now on the Airparts.aero Marketplace.

Overview

The Meggitt RG30 is a genuine OEM rubber grommet, an essential and purpose-built component for the installation of vent tube elbows on various Securaplane / Meggitt main ship and emergency aircraft batteries. This is not a standard hardware-store grommet; it is a precision-molded seal fabricated from a specialized elastomer, engineered 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 proper venting of gases.

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) 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 Sealing: Designed with precise dimensions to create a tight, positive seal in the battery case's vent port, preventing moisture, dirt, and contaminants from entering the battery box while ensuring vent gases are properly directed.
• OEM Specification: As a genuine Meggitt (Securaplane) component, 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 Maintenance: 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 battery installation.

Technical Specifications

• Part Number: RG30
• Manufacturer: Meggitt / Securaplane
• Component Type: Battery Vent Tube Grommet
• Material: Specialized Chemical-Resistant Elastomer
• Primary Application: Securing and sealing the vent tube elbow on Securaplane / Meggitt aircraft batteries.

Aircraft Compatibility

The RG30 grommet is not aircraft-specific, but rather battery-specific. It is used on a wide variety of aircraft that utilize the corresponding Meggitt / Securaplane main ship or emergency power batteries.

• Common Battery Models:
  • Used across numerous models in the Meggitt / Securaplane main and emergency battery lines. Verification against the specific battery's Component Maintenance Manual (CMM) is essential.
• Common Aircraft Platforms:
  • Business Jets: Gulfstream, Bombardier, Dassault Falcon, Cessna Citation
  • Commercial Airliners: Boeing, Airbus
  • Helicopters: Various models requiring high-performance battery systems.

Applications

The RG30 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) produced during the battery's charge/discharge cycles to the outside of the aircraft, preventing a hazardous buildup within the airframe.

Why Choose RG30?

The proper venting of an 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. Using a genuine Meggitt RG30 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 multi-thousand-dollar battery, there is no substitute for certified, genuine OEM parts.

The RG30 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. 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.
