Seal Ring

Built to restore reliable operation in high-cycle drilling systems, the Seal Ring (OEM reference 3115 3289 17) provides a replacement option for compatible Atlas Copco drilling applications. In the assembly, 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 BOOMER 282, BOOMER L2D and BOOMER M2C-SP.

The replacement is intended to perform under repeated pressure cycles, reciprocating or rotary movement, temperature changes and contamination typical of drilling service. Produced using application-matched sealing materials and accurately controlled profiles, it is intended to maintain dimensional stability and dependable function throughout demanding service. This supports stable sealing performance, cleaner operation and longer service intervals for the surrounding assembly.
