The Rolls-Royce 23053995 is an OEM aerospace gasket used in engine and accessory assemblies where a low-thickness sealing interface is required between flanged metallic components. It is a precision consumable sealing part designed to ensure leak-free operation in high-vibration, high-temperature aircraft engine environments.

The gasket features a circular sealing geometry with six mounting holes and is specified with a 2.52-inch inner diameter and approximately 0.020-inch thickness. It is commonly associated with Rolls-Royce (Allison) helicopter and light turbine engine accessory systems, where it serves as a static seal between housings, covers, or fluid system interfaces.

This part is classified under standard aerospace consumables (FSC 5330 – packing and gasket materials) and is typically replaced during scheduled maintenance or whenever the mating assembly is opened.

Key features include:

OEM Rolls-Royce aerospace sealing gasket
6-hole bolt pattern for flange-mounted assemblies
Thin-profile 0.020" sealing element for precision mating surfaces
Designed for engine accessory and helicopter system applications
High resistance to oil, fuel, and hydraulic fluid exposure
Suitable for high-temperature vibration-prone environments
Single-use consumable (recommended replacement at disassembly)
Used in legacy Allison / Rolls-Royce turbine-related assemblies
Classified under FAA aircraft consumable parts standards
Ensures proper sealing integrity in pressurized or lubricated systems
Supplied through Rolls-Royce aerospace distribution channels
