DISJEST Professional Series: High-Pressure Hydraulic Connectivity for Bobcat Fleet The DISJEST 6679837 & 6680018 Hydraulic Quick Coupler Set is a mission-critical component designed for the high-intensity auxiliary hydraulic systems of Bobcat loaders. In demanding construction and agricultural environments, the integrity of your fluid connectors dictates the uptime of your attachments. Our flat-face couplers are engineered to restore the pneumatic-like precision and hydraulic stability your equipment requires. Engineering Excellence & ISO Compliance: Following the international ISO 16028 standard, the DISJEST couplers offer universal interchangeability within the specified 46mm thread range. The flat-face design is specifically optimized to prevent "air inclusion" during coupling, ensuring that your hydraulic pump remains protected from cavitation. The heavy-duty internal valving is tested for pressure-pulse endurance, maintaining a secure lock even during high-vibration demolition or grading tasks. Built for the Elements: Thermal Range: Operational stability from -25°C to 125°C. Surface Protection: Reinforced plating to prevent oxidation and surface pitting in humid or muddy conditions. Compatibility: Covers Bobcat S-Series (S130, S250, S300, etc.), T-Series (T190, T590, T770, etc.), and E-Series excavators. Thread Accuracy: Guaranteed 46mm (1-13/16") outside diameter for 6679837 and 6680018 cross-referencing. The DISJEST Commitment: We understand that for heavy equipment operators, every hour in the shop is lost revenue. Our couplers are bench-tested for alignment and flow-rate consistency. By choosing DISJEST, you are investing in a component that meets the structural demands of Bobcat's rigorous workload, ensuring your machine stays on the job and your connections stay dry.
