O-Ring

Engineered as a durable aftermarket solution for drilling equipment, the O-Ring (OEM 0663 2101 68) 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. Listed compatibility includes BOLTEC 235, BOLTEC MC and BOLTEC MD.

During drilling operation, it must tolerate repeated pressure cycles, reciprocating or rotary movement, temperature changes and contamination typical of drilling service. With application-matched sealing materials and accurately controlled profiles, the component is intended to install accurately and work predictably with adjoining parts. This supports stable sealing performance, cleaner operation and longer service intervals for the surrounding assembly.

This Delkom aftermarket option is intended for maintenance programs that require dependable replacement parts and clear OEM cross-referencing. Ask for 120 101 575 when checking stock, lead time or technical compatibility.
