Is the Quick coupling plug with GZ BSPT valve, NITTO KOHKI SP CUPLA type A, brass suitable for steam at 180Â°C and 30â50 bar?

Quick coupling plug with GZ BSPT valve, NITTO KOHKI SP CUPLA type A, brass . based on the provided Nitto Kohki datasheet it is specified for steam service, with an operating temperature range up to +180Â°C (with Viton seals) and working pressures rated to 50 bar for sizes 1/8", 1/4", 3/8" and 30 bar for 1/2". Therefore, for steam at 180Â°C: - Sizes 1/8", 1/4", 3/8": rated to 50 bar . suitable for 30â50 bar steam at 180Â°C per the stated ratings and temperature limit (assuming Viton seals are fitted). - Size 1/2": rated to 30 bar . acceptable at the lower end (30 bar) but not suitable for 50 bar steam at 180Â°C. Caveats: confirm actual seal material is Viton, verify system transient pressures, chemical compatibility with steam conditions, and applicable safety/regulatory requirements. If any doubt, consult manufacturer or use a higher-rated component.

Can the Quick coupling plug with GZ BSPT valve, NITTO KOHKI SP CUPLA type A, brass be used with hydraulic oils at 50 bar and 180Â°C?

Yes. The Quick coupling plug with GZ BSPT valve, NITTO KOHKI SP CUPLA type A, brass is specified for use with hydraulic oils, with a working pressure up to 50 bar (for 1/8", 1/4", 3/8" sizes) and an operating temperature range up to +180Â°C when fitted with Viton seals. Therefore, for hydraulic oil service at 50 bar and 180Â°C it meets the stated material, pressure and temperature ratings-provided you are using one of the sizes rated at 50 bar and Viton sealing is confirmed. Verify chemical compatibility of the specific hydraulic oil with brass and Viton for long-term service and consider system safety margins and transient pressure/temperature spikes.

Can the Quick coupling plug with GZ BSPT valve, NITTO KOHKI SP CUPLA type A, brass be used with aggressive chemicals?

Quick coupling plug with GZ BSPT valve, NITTO KOHKI SP CUPLA type A, brass can be used with aggressive chemicals. with important caveats. Why it might be suitable: - The product description explicitly lists âchemicalsâ among intended media, and the brass body provides good mechanical durability. - Operating range: up to 50 bar (small sizes) / 30 bar (1/2") and -20Â°C to +180Â°C with Viton seals, which covers many industrial chemical service conditions. Limitations and cautions: - âChemicalsâ is a broad term; compatibility depends on the specific chemical, concentration, temperature and exposure time. - Brass is susceptible to dezincification and corrosion by ammonia, strong acids, chlorides, and certain aggressive solvents. It is generally not recommended for strong acids (e.g., concentrated HCl, H2SO4), strong alkalis at elevated temperature, or halogenated hydrocarbons unless manufacturer confirms. - Seals are Viton (fluoroelastomer) per the temperature note; Viton resists many oils, fuels and some solvents but is attacked by ketones (e.g., acetone), some esters, and certain amines. check chemical compatibility. - Pressure and temperature limits must not be exceeded; aggressive chemicals at high temperature/pressure accelerate degradation. Recommendation: - Provide the exact chemical name(s), concentration, temperature and expected exposure time to your supplier or Nitto Kohki to obtain a confirmed compatibility statement. - For highly aggressive or critical applications, consider alternative materials (stainless steel, special alloys, PTFE-lined components) or request manufacturer approval/testing. Short summary: Quick coupling plug with GZ BSPT valve, NITTO KOHKI SP CUPLA type A, brass may be usable for some chemicals, but verify compatibility for the specific chemical, concentration and conditions before use.
