Title: RK Series Hydraulic Couplings: Enhancing Safety and Efficiency in High-Pressure Systems
As hydraulic systems face growing pressure and performance demands, the RK Series Flat Face Thread-to-Connect Couplings provide a clean, leak-free solution. Engineered for heavy-duty applications from construction to oil drilling, their superior sealing and corrosion resistance ensure reliable performance and reduced downtime in harsh industrial environments.
The RK Series Flat Face Thread-to-Connect Hydraulic Couplings provide reliable, leak-free connections for high-pressure systems up to 420 bar. Featuring a flat face valve system, they minimize fluid loss and simplify cleaning, while the thread-lock design ensures secure, vibration-resistant performance—even under residual pressure. Made of carbon steel with durable Zn-Ni plating, these couplings offer excellent corrosion resistance and long service life. Available with BSP, NPT, and SAE threads, the RK Series includes NBR standard seals and optional FKM or EPDM materials for broader temperature and chemical compatibility. Ideal for agricultural machinery, construction equipment, special vehicles, oil drilling platforms, and metallurgical industries requiring safe, clean, and durable hydraulic connections.
