Is the Full-flow quick coupling plug with GZ BSPT, NITTO KOHKI TSP CUPLA, stainless steel AISI 304 suitable for high-viscosity lubricants at 75 bar?

Yes. The Full-flow quick coupling plug with GZ BSPT, NITTO KOHKI TSP CUPLA, stainless steel AISI 304 is suitable for high-viscosity lubricants at 75 bar for the sizes specified (1/8", 1/4", 3/8"). The product is explicitly recommended for highâviscosity fluids such as lubricants, constructed from corrosionâresistant AISI 304, and rated to 75 bar working pressure for those smaller thread sizes. Operating temperature range (-20Â°C to +80Â°C with NBR seals) and compatibility with oils are appropriate for typical lubricant applications. Notes/limits: the 75 bar rating applies only to 1/8", 1/4", 3/8" sizes . larger sizes have lower maximum pressures (45 bar for 1/2"â3/4", 30 bar for 1Â¼"â1Â½", 20 bar for 2"), so verify your systemâs hose/line size and peak pressures. Also confirm lubricant temperature and chemical compatibility with NBR seals; for higher temperatures or NBRâincompatible fluids consider alternative seal materials.

Can Full-flow quick coupling plug with GZ BSPT, NITTO KOHKI TSP CUPLA, stainless steel AISI 304 be used with chemicals at operating temperatures down to -20Â°C?

Yes. Full-flow quick coupling plug with GZ BSPT, NITTO KOHKI TSP CUPLA, stainless steel AISI 304 can be used with chemicals at operating temperatures down to -20Â°C, with caveats. Why: The product specification lists compatibility with chemicals and an operating temperature range from -20Â°C to +80Â°C (NBR seal). The body material AISI 304 stainless steel provides good general corrosion resistance to many chemicals, and the coupling is designed for fluids including chemicals, hydraulic oils, steam, air and gases. Caveats and recommendations: - Seal material: The stated temperature range is tied to NBR (nitrile) seals. NBR has limited chemical resistance to certain solvents, ketones, strong acids, and aromatics and becomes less flexible at low temperatures. Verify chemical compatibility of NBR with your specific chemical(s). If incompatible, consider alternative seal materials (e.g., FKM/Viton, EPDM) if available. - Chemical compatibility: AISI 304 resists many but not all chemicals. Strong chlorides, strong acids (e.g., hydrochloric, sulfuric at certain concentrations/temperatures) and some halogenated hydrocarbons can cause corrosion or stress corrosion cracking. Check compatibility charts for both the stainless steel and seal versus your specific chemical, concentration and exposure duration. - Pressure/temperature effects: Ensure working pressure ratings (depend on coupling size) are acceptable under your operating temperature and fluid conditions. - Low-temperature performance: At -20Â°C, NBR may stiffen; functionality for quick coupling operation should be validated in application. - Safety testing: Perform compatibility testing (soak and pressure/leak tests) under real operating conditions before service. Conclusion: Technically usable at -20Â°C for many chemicals per the specification, but confirm compatibility of NBR seals and AISI 304 with your exact chemicals, concentrations and pressures; if incompatible, request alternative seal materials or a different alloy.

Q: Can Full-flow quick coupling plug with GZ BSPT, NITTO KOHKI TSP CUPLA, stainless steel AISI 304 be used with steam at 75 bar?

Yes - Full-flow quick coupling plug with GZ BSPT, NITTO KOHKI TSP CUPLA, stainless steel AISI 304 is rated for steam use at the stated working pressure only if within its published limits: for 1/8", 1/4" and 3/8" sizes the working pressure is 75 bar and the material and description list steam as a compatible medium. However note the sealing material (NBR) limits the operating temperature to -20Â°Câ¦+80Â°C; saturated steam at high pressure often exceeds 80Â°C, so verify actual steam temperature. If steam temperature â¤80Â°C and size is 1/8", 1/4" or 3/8", it can be used at 75 bar; otherwise select a higherâtemperature seal or a coupling sized/rated for the intended pressure and temperature.
