In agricultural hydraulic circuits, sealing failures can halt a harvester mid-season and drive up maintenance costs. The dual sealing system with O-ring helps eliminate leaks even under intense vibration and pressure spikes, reducing unplanned downtime and fluid loss by up to 95% when installed according to specifications.
The self-centering 24° cone speeds up assembly by up to 40% compared to conventional fittings, reduces rework, and improves torque repeatability.
Helesul DKO (Double Cone O-ring) hydraulic adapters are engineered for high-reliability sealing in high-pressure hydraulic systems, combining a self-centering 24° cone and an O-ring to deliver consistent performance in agricultural machinery and road applications.
With a robust construction, they reduce leaks, simplify assembly, and increase equipment uptime even under vibration, heavy-duty cycles, and harsh environments.
All Helesul hydraulic adapters are manufactured in accordance with ISO, SAE, and DIN standards, ensuring interchangeability, safety, and predictable field performance.
