4K1557 Beaded Gasket for Caterpillar Equipment

The 4K1557 beaded gasket is a sealing component used between mating surfaces on Caterpillar equipment. It is used for sealing joints against leakage and contamination and is listed for Caterpillar articulated dump trucks and Caterpillar engine-machine applications.

This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

Fitment

The gasket is listed for the following Caterpillar equipment types and models:

• Caterpillar articulated dump trucks
• Caterpillar engine-machine applications
• Caterpillar D350E
• Caterpillar D400E

• Caterpillar 3208
• Caterpillar 3406
• Caterpillar 3406C
• Caterpillar 3408
• Caterpillar 3408C
• Caterpillar 3408E

Fitment should be checked against the equipment model and the part number removed from the machine before installation. The listed applications include both complete machine models and engine designations, so the installation position may depend on the specific equipment configuration.

Cross-reference numbers

4K1557 and 4K-1557 refer to the same listed gasket number in different number formats. The hyphenated form is included for catalog and parts-identification purposes.

Specifications

The gasket dimensions are specified by the inner diameter and the cross-section measurements. The supplied package dimensions are listed separately as length, width, and depth in centimetres. The material designation NBR identifies nitrile rubber as the gasket material.

The part forms a sealing interface between two mating surfaces. Its listed application is to help prevent leakage and contamination at the joint. The actual mounting location is not specified in the available part data and may vary between the listed Caterpillar machine and engine applications.
