Product description

Highlights at a glance

  • Steel Zinc Plated Hydraulic quick coupler - steel zinc-plated hydraulic quick couplers pair a hardened steel core with an anti-rust finish, built for the mud, rain, and constant washdowns that excavators endure on construction sites. The zinc plating shields the body against moisture and corrosion, so the coupler keeps working and looking right even in tough outdoor service. Beneath the finish, the hardened steel delivers the strength to handle high working pressure and the repeated coupling cycles of daily attachment changes without deformation. The combination of rugged strength and corrosion protection makes zinc-plated couplers a dependable, economical choice for excavator fleets, rental machines, and any equipment that works outdoors all year.
  • Poppet valve quick disconnect - poppet valve quick disconnects open fully for maximum flow and seat positively on disconnect, giving excavator breakers and high-flow attachments the oil delivery they need while cutting pressure drop and oil waste. The poppet lifts completely out of the flow path during connection, allowing unrestricted fluid movement that keeps the hammer or shear responsive under heavy load. On separation, the valve seats firmly to seal the line instantly, preventing drips and keeping the work area clean around the machine. With reduced wear on sealing surfaces and consistent performance cycle after cycle, poppet valve quick disconnects balance efficiency, reliability, and ease of use for demanding excavator service.
    • Frequently asked questions

    This coupler supports a tilt of 45 degrees left and right (with some models supporting up to 90 degrees). This allows you to easily complete complex tasks like slope finishing, trenching, and angled back filling without moving the excavator chassis, increasing overall construction efficiency by more than 30%.

    Safety is our top priority. We are equipped with a Double Locking System: the hydraulic safety lock ensures convenience and firmness in daily operations, while the physical Safety Pin serves as the final line of defense. Even if the hydraulic system pressure is abnormal, it ensures the attachment will not fall off, complying with international safety standards.

    We primarily use high-strength wear-resistant steel (such as Q355B or original Hardox 450) to manufacture key stress-bearing components. All welds undergo strict ultrasonic flaw detection and stress relief treatment to ensure the coupler has an extremely long service life even under heavy-duty conditions like mining and demolition.

    We provide a "Plug and Play" engineering design. Installing a tilt coupler typically requires two sets of two-way hydraulic lines (one for locking and one for tilting). We provide detailed installation manuals and video guidance with the shipment to ensure your technicians can get started quickly.
