Is the Stainless Steel BSPT Male Plug, NITTO KOHKI TSP CUPLA Full-Flow Quick Coupling suitable for steam and high-viscosity lubricants at rated pressures and temperatures?

Yes. The Stainless Steel BSPT Male Plug, NITTO KOHKI TSP CUPLA, Full-Flow Quick Coupling is suitable for steam and high‑viscosity lubricants within its specified rated pressures and temperatures. Made from AISI 304 stainless steel, it resists corrosion and wear and is explicitly stated as compatible with steam and high‑viscosity fluids such as lubricants. Rated working pressures are size-dependent (up to 75 bar for 1/8", 1/4", 3/8"; 45 bar for 1/2" and 3/4"; 30 bar for 1¼" and 1½"; 20 bar for 2") and the operating temperature range is −20°C to +80°C (NBR). Use within those pressure and temperature limits is appropriate; if your steam system exceeds 80°C or uses different seal materials, verify seal compatibility and safety margins before use.

Can the Stainless Steel BSPT Male Plug, NITTO KOHKI TSP CUPLA, Full-Flow Quick Coupling be used with various hydraulic oils and chemicals across its specified pressure and temperature ranges?

Stainless Steel BSPT Male Plug, NITTO KOHKI TSP CUPLA, Full-Flow Quick Coupling Format Yes — the TSP CUPLA stainless steel BSPT male plug is suitable for use with a wide range of hydraulic oils and many chemicals within its specified pressure and temperature limits. Constructed from AISI 304 stainless steel and designed as a full‑flow coupling, it is explicitly intended for media such as water, hydraulic oils, steam, chemicals, air and gases, and handles high‑viscosity fluids (e.g. lubricants) effectively. Pressure ratings vary by size (up to 75 bar for 1/8", 1/4", 3/8"; 45 bar for 1/2" and 3/4"; 30 bar for 1¼" and 1½"; 20 bar for 2") and the operating temperature range is −20°C to +80°C with NBR seals. Caveats: compatibility with specific hydraulic fluids or aggressive chemicals depends on chemical compatibility with AISI 304 stainless steel and NBR seal material. For aggressive acids, strong alkalis, certain solvents or temperatures outside the stated range, verify compatibility with manufacturer chemical charts or choose alternative seal materials. Always ensure system pressure and temperature remain within the listed limits for safe, reliable operation.
