Is the Brass Full-Flow Quick Coupling Socket with BSPT Male Thread, NITTO KOHKI TSP CUPLA compatible with hydraulic oils and high-viscosity lubricants?

Yes. The Brass Full-Flow Quick Coupling Socket with BSPT Male Thread, NITTO KOHKI TSP CUPLA is compatible with hydraulic oils and high‑viscosity lubricants. Made from durable brass and designed for a wide range of media—including hydraulic oils and high‑viscosity fluids—it ensures smooth, efficient flow for lubricants. It supports working pressures up to 50 bar (for 1/8", 1/4", 3/8"), 30 bar (1/2", 3/4", 1"), 20 bar (1.1/4", 1.1/2") and 15 bar (2"), and operates between −20°C and +80°C with NBR sealing, providing reliable performance in typical hydraulic and lubricant applications.

Can the Brass Full-Flow Quick Coupling Socket with BSPT Male Thread, NITTO KOHKI TSP CUPLA withstand continuous operation at temperatures near its upper limit (+80°C) without seal degradation?

Yes — the Brass Full-Flow Quick Coupling Socket with BSPT Male Thread, NITTO KOHKI TSP CUPLA can withstand continuous operation near its upper temperature limit (+80°C) without seal degradation, provided the specified NBR (nitrile) sealing is used and operating conditions stay within the stated limits. The product’s rated operating range is −20°C to +80°C with NBR seals, and the pressure ratings given for each size assume use within that temperature envelope. Caveats: - Continuous exposure at the extreme (+80°C) accelerates NBR aging compared with moderate temperatures; for maximum seal life, avoid sustained operation at the absolute limit when possible. - Compatibility with specific media (some chemicals and steam) and pressure/temperature combinations should be verified, as certain aggressive fluids or repeated thermal cycling can shorten seal life. - For critical applications or higher temperatures, consider alternative seal materials (e.g., FKM) or periodic inspection/replacement intervals.
