Seal

Engineered for reliable service on rock drilling equipment, the Seal (OEM 4350 2618 03) is an aftermarket replacement for Atlas Copco rock drilling and related equipment. It helps contain hydraulic oil, air or flushing media while keeping dirt and abrasive contamination away from critical interfaces. The compatibility data covers applications such as DHR 6H, DHR 6H-SH and FLEXIROC D65 -10SF.

Its design focuses on repeated pressure cycles, reciprocating or rotary movement, temperature changes and contamination typical of drilling service. Construction based on application-matched sealing materials and accurately controlled profiles helps the part retain its functional geometry under repeated use. As a result, it supports stable sealing performance, cleaner operation and longer service intervals for the surrounding assembly.

Delkom supplies this item as a cost-conscious alternative for maintaining Atlas Copco drilling machinery without compromising the focus on fit and service reliability. Reference 120 102 713 for availability and quotation requests.
