NITTO KOHKI 12TPM Valveless Steel Air Coupler Plug 1-1/2"

The product belongs to the "TSP Cupla" series, characterized by its "valveless internal structure" (Valveless Structure / Open Type). Designed for large-scale compressed air distribution systems or circulating high-viscosity fluids, this design eliminates pressure drop issues, allowing air, gas, or liquids to flow at 100% full capacity without performance loss, conforming to advanced manufacturing standards directly from Japan.
Features

Valveless High-Flow Structure: Clear internal bore without any valve mechanism or spring obstructing the flow path, providing maximum flow rate and completely reducing system resistance.

Heavy Duty Hardened Steel Body: The body is made from specially hardened steel, resistant to high impacts and severe vibrations, reducing wear from heavy industrial operations.

Low Pressure Drop: Perfectly suited for systems requiring consistently stable pressure, as zero internal resistance enhances overall machine efficiency.

Secure Thread Precision: High-precision 1-1/2 inch male thread standard (R 1-1/2"), easily and safely fastening tight to main pipe fittings.

Ideal for connecting main compressed air lines (Main Air Line) in industrial plants requiring massive air volume to supply large machinery.

Used in industrial fluid circulation systems such as hydraulic oil, machinery cooling water, or high-viscosity lubricating oil

Suitable for high-pressure fuel filling systems, gas pipeline systems, or smelting and mining industries that operate under constant heavy-duty conditions

Used for connecting to large screw air compressors, construction equipment, or high-power hydraulic machinery
