O-Ring 1/16 x 1in 2nd Generation

The O-Ring 1/16 x 1in 2nd Generation from BERT TRANSMISSIONS (part number SG-1081) is a precision rubber seal engineered for Bert Second Generation transmission applications. These o-rings are critical internal components that prevent fluid leakage and maintain pressure integrity within the transmission assembly, making them essential for anyone performing transmission maintenance, rebuild, or repair work on systems using Bert's second-generation transmission platform.

This specific o-ring features a 1/16-inch cross-section with a 1-inch inner diameter, dimensions that correspond to internal seal positions within Bert transmission housings. The rubber composition is formulated to withstand the thermal cycling and fluid exposure that transmissions experience during operation. Proper o-ring sealing is directly tied to transmission performance—degraded or missing seals lead to fluid loss, pressure drop, and potential internal damage. Replacement o-rings ensure the transmission maintains its designed operating envelope and extends component life.

This o-ring is intended for builders and technicians rebuilding or servicing Bert Second Generation transmissions. Whether addressing a slow leak detected during operation, performing preventive maintenance during a full rebuild, or replacing aged seals as part of a comprehensive overhaul, this component is sold individually, allowing you to purchase only the exact seals needed for your application. Part number SG-1081 ensures correct fitment and material compatibility with Bert transmission specifications.

Bert Transmissions serves the high-performance drag racing and street performance community, and their second-generation transmission line represents evolution of sealing design and internal geometry. Using OEM-equivalent or manufacturer-specified replacement seals—rather than generic o-ring substitutes—ensures reliability under the duty cycles these transmissions experience. Stocking the correct seal specification before beginning work prevents mid-project delays and guarantees seal compatibility with internal transmission geometry.
