Screw-to-connect hydraulic quick coupling
Quick couplings used mainly in construction machinery due to the ease and reliability of the connection thanks to the thread used. They work well at high pressures due to their massive construction. Ideal for construction machinery. Used in very demanding hydraulic installations where ordinary poppet quick couplings wear out / damage too quickly.
Highly durable quick couplings
A series of screw-to-connect quick couplings with a poppet valve, which perform excellently in extreme conditions. Made of high-quality carbon steel with a Cr III zinc coating and NBR sealing. A special, additionally reinforced construction ensures increased strength of the screw connection. VD series screw-to-connect quick couplings are ideal for use with high pulse pressure in the hydraulic system (hydraulic hammers). This type of quick coupling is much more durable and resistant to damage than ordinary poppet quick couplings.
