Is the Hydraulic Quick Coupling Plug with BSP Female Thread, TEMA Standard, No Valve compatible with hydraulic oils and other industrial fluids at up to 450 bar?

Yes. The Hydraulic Quick Coupling Plug with BSP Female Thread, TEMA Standard, No Valve is designed for hydraulic power transmission with hydraulic oils and a wide range of industrial fluids (water, steam, fuels, oils, gases, chemicals) and is rated for working pressures up to 450 bar depending on diameter. Constructed from chrome‑plated brass (≤1") or galvanized steel (>1") and built to a 4:1 safety factor, it offers compatibility and durable performance with hydraulic oils and other industrial fluids at pressures up to 450 bar when used within the specified diameter/pressure ratings and application conditions.

Can the Hydraulic Quick Coupling Plug with BSP Female Thread, TEMA Standard, No Valve be used in high-temperature steam or chemical service without additional seals or protective coatings?

No — the Hydraulic Quick Coupling Plug with BSP Female Thread, TEMA Standard, No Valve is designed for use with hydraulic oil and a broad range of industrial media (water, steam, fuels, oils, gases, chemicals) and is manufactured from chrome-plated brass (up to 1") or galvanized steel (larger sizes), offering good wear and corrosion resistance. However, use in high-temperature steam or aggressive chemical services without additional seals or protective coatings is not recommended as a general rule. High temperatures, aggressive chemicals, and steam can degrade standard metal platings and any internal sealing materials (if present), accelerate corrosion, cause embrittlement or stress corrosion cracking in brass or galvanized steel, and compromise leak-tightness and safety. For such applications you should verify compatibility with the specific temperature, pressure and chemical environment, confirm the material limits and any seal materials with the manufacturer, and where necessary specify high-temperature materials, chemical-resistant coatings or special seal materials designed for steam/chemical service.
