Cup Seal

Suitable for scheduled maintenance and component renewal, the Cup Seal (OEM reference 0667 1206 00) 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. The part is associated with compatible applications such as BOOMER 104, BOOMER 282 and BOOMER L2D.

For long-term reliability, the part is designed around repeated pressure cycles, reciprocating or rotary movement, temperature changes and contamination typical of drilling service. The use of application-matched sealing materials and accurately controlled profiles supports consistent fit at the relevant interfaces and reliable operation after replacement. In practical maintenance terms, this supports stable sealing performance, cleaner operation and longer service intervals for the surrounding assembly.

For workshops and fleet operators, this Delkom alternative offers a straightforward replacement route for the referenced Atlas Copco application. Delkom part number 120 100 034 can be used for ordering, cross-reference checks and volume pricing.
