Nitto HSU coupler for high pressure, mating size R1/4, pressure resistance (MPa) 31.5 (47943) HSU-2S SUS HNBR 1 piece

Catalog number: HSU-2S SUS HNBR Features: ● Made of stainless steel with excellent corrosion resistance. ● After connecting the coupler, the three-lock mechanism can be easily and securely locked by simply turning the sleeve. ● The main body is made of stainless steel (SUS304) with excellent corrosion resistance. ● Suitable for use in harsh environments such as marine development. ● New design achieves compactness and increased flow rate. (Compared to S210 coupler) ● Although made of stainless steel, it achieves the same maximum operating pressure of 21.0 MPa (214 kgf/cm2) as steel. ● Equipped with a separation prevention mechanism to prevent accidental separation after connection. ● Both the socket and plug have built-in automatic opening and closing valves to prevent fluid leakage when separated. ● Hydrogenated nitrile rubber (HNBR) is used as the sealing material, making it compatible with a wide range of fluids. Specifications: ● Pressure resistance (MPa): 31.5 ● Counterpart mounting size: R1/4 ● Fluid used: Water, hydraulic oil, gas ● Maximum operating pressure (MPa): 21.0 ● Operating temperature range (℃): -20 to 180 ● Counterpart mounting screw size: R 1/4 ● Two-way opening and closing type ● Valve structure: Two-way opening and closing type ● Made of stainless steel with excellent corrosion resistance. ● Equipped with a separation prevention mechanism that can be easily locked by simply turning the sleeve after connecting the "coupler". Material/Finish: ● Body: Stainless steel (SUS304) ● Sealing rubber: Hydrogenated nitrile rubber (HNBR)
