NITTO KOHKI SP Cupla Type A BSBM 6S-A Brass Coupler Two-Way Shut-Off

NITTO KOHKI Brass Air Coupler Model BSBM 6S-A, Two-Way Shut-Off System
The NITTO KOHKI BSBM 6S-A 3/4-inch (female thread) brass quick coupler is a premium "S-A Type" series coupler from Japan. It features an automatic two-way shut-off valve mechanism in both the socket and plug. When disconnected, valves on both sides instantly close the flow passages, preventing any fluid or air leakage from the system, preserving line pressure, and keeping external contaminants from entering the system. The body is made of genuine high-quality brass, making it robust, corrosion-resistant, and rust-free. Ideal for use with air, gas, liquid chemicals, or water systems.
Features
Two-Way Shut-Off Valve: Maximum safety with automatic piston valves on both sides. Prevents oil, air, or liquid from spraying upon disconnection, meeting the demands of jobsites requiring ultimate cleanliness and safety.
Solid Brass Construction: The body is made from industrial-grade brass, providing outstanding wear resistance, weather resistance, and corrosion resistance against moisture.
Special-Grade NBR Rubber Seal: Fitted with high-elasticity Nitrile Rubber (NBR) sealing that offers excellent resistance to oil corrosion, lubricants, and pneumatic pressure, completely preventing leakage.
High Flow Rate: The precisely engineered internal flow path minimizes pressure drop, allowing air or fluid to flow at full efficiency.
Applications
Suitable for plant air supply systems, pneumatic equipment, and automated machinery requiring high safety levels.
Used with piping for dilute chemicals, machine coolant, or low-pressure hydraulic oil systems.
Ideal for jobsites requiring frequent hose disconnection without leaving fluid or air leaks dripping onto work surfaces.
Used for connecting large 3/4-inch air supply lines to primary pneumatic tools in shipyards, automotive assembly plants, or heavy industries.
