• Flat face valve minimizes fluid spillage and air inclusion during disconnection, ideal for overhead hydraulic applications.
• Threaded sleeve lock provides robust mechanical retention to prevent accidental disconnection under vibration or external impact.
• Anti-blowout bonded seal prevents internal damage or seal loss during high-pressure disconnects.
• Dirt-resistant sleeve cover keeps the retaining ring and locking components clean, ensuring smooth operation over time.
• Zinc-plated finish with yellow chromate coating provides extended corrosion resistance in aggressive environments.
• Compact design with no internal poppet separation allows quick and easy flushing and maintenance.
• Fully compatible with NITTO 350 series couplings.
The internal guiding structure is designed to reduce the ingress of debris during connection or disconnection. The rotating sleeve engages a spring-loaded dust seal to protect the retaining ring area. Compact profile fits standard hydraulic thread ports, enabling quick coupling even in tight spaces.
