HSC Series – Heavy-Duty Screw-Connect Couplers (ROFLEX Compatible)
The HSC Series heavy-duty screw-connect couplers are engineered to provide unmatched reliability and performance in high-pressure hydraulic applications. Designed to be ROFLEX compatible, these couplers are ideal for heavy-duty systems requiring secure, leak-free connections under extreme conditions. With a robust screw-to-connect mechanism and precision engineering, the HSC Series ensures superior performance in industries such as construction, mining, and agriculture.
Fully compatible with ROFLEX screw-connect couplers, ensuring easy integration into existing systems with no need for modifications.
Manufactured from premium-grade steel with advanced surface treatments, these couplers are built to withstand extreme pressures, heavy loads, and harsh environments.
Capable of handling pressures up to 600 bar (8700 PSI) or more, making the HSC Series suitable for demanding hydraulic systems.
The threaded connection mechanism ensures a secure and stable connection, eliminating risks of accidental disconnection, even in high-vibration applications.
