Is the Brass Full-Flow Quick Coupling Socket with Hose End, NITTO KOHKI TSP CUPLA, compatible with hydraulic oils and steam at 50 bar?

Brass Full-Flow Quick Coupling Socket with Hose End, NITTO KOHKI TSP CUPLA Format Yes — the Brass Full-Flow Quick Coupling Socket with Hose End, NITTO KOHKI TSP CUPLA is compatible with hydraulic oils and steam, subject to pressure, size and seal selection. It is explicitly designed for media including hydraulic oils and steam. Working pressure limits depend on size: up to 50 bar for small sizes (1/8", 1/4", 3/8"), 30 bar for 1/2", 3/4", 1", 20 bar for 1¼"–1½" and 15 bar for 2". Seal material affects temperature/steam suitability: NBR seals for −20°C to +80°C, Viton seals up to +180°C. For steam at high temperatures/pressures choose Viton seals and ensure selected size’s pressure rating meets your 50 bar requirement (only 1/8", 1/4", 3/8" rated to 50 bar).
