Is the Full-Flow Quick Coupling Socket, BSPT Female, NITTO KOHKI TSP CUPLA in AISI 304 Steel compatible with hydraulic oils and steam at up to 75 bar?

Yes. The Full-Flow Quick Coupling Socket, BSPT Female, NITTO KOHKI TSP CUPLA, AISI 304 Steel is compatible with hydraulic oils and steam. It is specifically designed for media including hydraulic oils and steam, and its construction in AISI 304 stainless steel provides corrosion and wear resistance. Working pressure capability is up to 75 bar for smaller sizes (larger diameters rated to 20 bar), and temperature compatibility ranges from −40°C to +180°C depending on seal material (NBR, Viton, or EPDM). Ensure you select the correct coupling size and seal material for your specific hydraulic oil type and steam conditions to meet pressure and temperature requirements.

Can the Full-Flow Quick Coupling Socket, BSPT Female, NITTO KOHKI TSP CUPLA, AISI 304 Steel be used with high-viscosity lubricants and gases across its full temperature range?

Yes. The Full-Flow Quick Coupling Socket, BSPT Female, NITTO KOHKI TSP CUPLA, AISI 304 Steel is suitable for use with high‑viscosity lubricants and gases across its specified temperature range. Constructed from AISI 304 stainless steel and designed for full‑flow performance, it handles high‑viscosity fluids such as lubricants with smooth flow and minimal pressure loss. Service temperatures span −40°C to +180°C depending on sealing material (NBR, Viton, or EPDM), and the coupling supports various media including oils and gases at working pressures up to 75 bar (smaller sizes) and 20 bar (larger diameters). Ensure you select the appropriate seal material for your specific temperature and chemical compatibility to maintain reliable performance.
