NITTO KOHKI 10TPM SUS Stainless Steel Male Coupler Plug 1-1/4" Valveless Type

NITTO KOHKI TSP Cupla model 10TPM SUS is a 1 1/4-inch male coupler plug with male thread, manufactured from 100% genuine Japanese premium stainless steel. It features an open, straight-through (valveless) engineered structure with no valve mechanisms, springs, or internal metal shafts in the fluid path. This innovation completely prevents and minimizes resistance that causes pressure drop, allowing liquids, air, gas, or high-viscosity fluids (such as hydraulic oil, lubricating oil, and grease) to flow through the large opening at a full 100% flow rate without losing pressure throughout the piping system.

The stainless steel material of the TSP Cupla series offers extremely high purity and metal density, providing absolute rust resistance, chemical liquid corrosion resistance, acid-base vapor resistance, and outstanding resistance to extreme hot and cold temperatures. The coupler body and male thread port undergo precision machining, enabling it to securely and smoothly connect and lock with the same size TSP series female coupler socket. It is easy to lock and unlock by hand, provides absolute leak prevention, and meets the demands of chemical engineering applications, food processing plants, and all types of heavy industrial production lines.

Straight-Through Valveless Design: No internal valve mechanism obstructing the fluid path, allowing air and liquids to flow at full capacity, preventing pressure drops, and eliminating chemical sediment clogging inside the coupler.

Premium Japanese Grade Stainless Steel Material: Superior corrosion resistance against chemical rust and salt vapor; safe for clean industries and harsh liquid chemicals.

Secure and Quick Connection: Male plug dimensions are manufactured to high precision standards, locking securely into the female socket and delivering excellent resistance to cumulative vibrations in piping systems.

1 1/4" Male Thread Port: Sharp, deep threads connect tightly to female pipes or main system valves, supporting working pressures up to 3.0 MPa.

Easy Maintenance and Long Service Life: Since it contains no complex internal spring mechanisms, it is easy to clean, prevents internal spring corrosion, and offers a service life many times longer than conventional couplers.

Ideal for piping systems conveying chemicals, liquid reagents, and acid-base vapors in chemical plants and laboratory facilities.

Used in hot and cold water piping systems for cooling plastic molding machines or large metal processing machinery requiring high flow rates with zero pressure drop.

Suitable for food processing, beverage industries, and water treatment systems that require 100% hygiene control and rust-free operation.

High-flow pneumatic systems as well as transfer systems for viscous fluids such as engine oil and hydraulic oil.
