NITTO KOHKI 4P-M-A Brass Quick Connect Plug - FKM, High Flow

NITTO KOHKI 4P-M-A BRASS FKM High-Flow Brass Quick Connect Plug
The NITTO KOHKI 4P-M-A BRASS FKM (TSP Cupla) is a 1/2-inch male threaded quick-connect plug, a high-quality product adhering to genuine Japanese engineering standards. The TSP Cupla series couplers feature a "valveless" internal design for both the socket and plug sides, completely eliminating obstructions in the air and fluid flow path. This delivers a 100% full maximum flow rate without any pressure drop in the system. The body is made of premium-grade brass, offering high rust and corrosion resistance. Fitted with an FKM (Fluororubber) seal offering superior chemical and heat stability, it can be safely used with compressed air, water, dilute chemical fluids, and industrial oils.
Features
Maximum Flow Rate & Zero Pressure Drop: Clear internal passage with no springs or valve stems to obstruct flow; ideal for systems requiring fast, high-volume, and continuous flow.
Premium Brass Body: The body is made of specially selected brass, sturdy, durable, with excellent torque resistance, and rust-free throughout its service life
Advanced FKM Seal: Top-grade fluoroelastomer (FKM) rubber seal, resistant to chemicals and lubricating oils, with higher heat resistance than standard rubber seals, securely preventing leaks
High Pressure Precision: Supports standard working pressure up to 5.0 MPa (51 kgf/cm²), manufactured with high-precision CNC machines to NITTO Japan factory standards, thread connects securely without stripping easily
Applications 
Suitable for installation in main high-pressure compressed air distribution systems, industrial water pipelines, oil lines, and diluted chemical lines where system pressure drops must be prevented
Suitable for connecting heavy-duty pneumatic tools with very high air consumption, or for use in chemical, food, and beverage industries that require safety and rust-free performance
