6K7704 O-Ring Seal

The 6K7704 O-ring seal is a rubber sealing part used in Caterpillar equipment. It is installed between fixed or moving mating parts to form a seal at the connection and is used in applications where the specified O-ring dimensions are required.

This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts). The part is identified by SKU 6K7704 and belongs to the O-Ring Seals category.

The seal has a round cross-section and is intended for use as an O-ring rather than as a flat gasket or formed seal. The available product data identifies the material as rubber and the design as uncoated. The stated dimensions and weight are provided below for part identification and compatibility checking.

Fitment

The 6K7704 O-ring is used on the following Caterpillar wheel loader models:

• Caterpillar Wheel Loader 920
• Caterpillar Wheel Loader 930
• Caterpillar Wheel Loader 930R
• Caterpillar Wheel Loader 930T

Fitment should be confirmed against the equipment model, the application location and the required seal dimensions before installation. The listed model range identifies the Caterpillar machines associated with this part number in the available product data.

Cross-reference numbers

The part is also identified by the following formatting of the same part number:

• 6K-7704

6K7704 and 6K-7704 refer to the same identification number, with the hyphen used in the latter format. No additional equipment-manufacturer or supplier part numbers are specified in the available data.

Specifications

The cross-section diameter and inner diameter describe the O-ring profile and internal opening. The listed length, width and depth are retained as supplied in the product data. Because an O-ring is a circular component, these dimensional entries should be compared with the corresponding catalogue or service-manual dimensions for the installation location.

When replacing the seal, the part number, dimensions and application position should correspond to the Caterpillar machine and assembly being serviced. The seal should be installed in the designated groove or sealing interface for the relevant component.
