O-Ring

Designed for demanding drilling service, the O-Ring (OEM reference 0663 2113 46) supports reliable servicing of Atlas Copco rock-drilling equipment. Within its operating system, the component helps contain hydraulic oil, air or flushing media while keeping dirt and abrasive contamination away from critical interfaces. Typical listed applications include DHR 6H, DHR 6H-SH and FLEXIROC D65 -10SF.

Its working environment commonly involves 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.

Supplied as a Delkom aftermarket alternative, this part gives maintenance teams a practical cross-reference option for Atlas Copco drilling equipment. Use Delkom reference 120 101 227 when requesting availability, quantity pricing or technical support.
