Retainer Seal

Description

Developed as a practical replacement option for hard-working drill rigs and drifters, the Retainer Seal (OEM HD709-01040) is used within the percussion and drifter assembly. By maintaining a controlled sealing barrier, the part supports pressure stability and reduces unwanted fluid loss or contaminant ingress.

Application data associates this reference with HCR 900-DS and HCR 900-DSII; configuration and serial-number checks are recommended before purchase. For overhaul and repair planning, the component provides a competitive alternative to original-supply-only purchasing. Sealing geometry and material selection are intended for repeated pressure cycles, fluid exposure, temperature variation and contamination encountered in drilling service.

Delkom combines rock-drilling spare-parts expertise with broad export capability for mining and tunneling customers. For purchasing support, bulk requirements or fitment confirmation, use Delkom reference 130 100 159 and OEM reference HD709-01040.
