Is the Brass DN5 Threaded Quick Connector Plug, Valve-Free, Series 21KA compatible with both BSP and metric thread standards?

Yes. The Brass DN5 Threaded Quick Connector Plug, Valve-Free, Series 21KA is compatible with both BSP and metric thread standards. It is offered with either external or internal BSP or metric threads, ensuring broad compatibility with a wide range of systems.

Can the Brass DN5 Threaded Quick Connector Plug, Valve-Free, Series 21KA withstand continuous operation at temperatures near its +100°C limit without accelerated wear?

Brass DN5 Threaded Quick Connector Plug, Valve-Free, Series 21KA can operate continuously near its maximum rated temperature of +100°C, but running any component consistently at the upper limit of its specified operating range increases the risk of accelerated wear and reduced service life. Key considerations: - Material: Brass body provides good high‑temperature strength and corrosion resistance, but seals, internal plastics or elastomers (if present) are more likely to degrade faster at prolonged exposure to ~100°C. - Design/ratings: The product is specified for -20°C to +100°C and up to 35 bar, so operation within these limits is intended and safe from an immediate failure standpoint. - Practical impact: Continuous service near +100°C can cause faster hardening, embrittlement or compression set of non‑metallic parts, potentially increasing leak risk or reducing smoothness of one‑handed operation over time. - Mitigation: To avoid accelerated wear, consider periodic inspection, use of compatible high‑temperature seals if available, keeping pressures moderate, and allowing cooling cycles if feasible. Conclusion: It is designed to work at +100°C, but for long‑term reliability you should avoid continuous operation at that extreme or implement monitoring and higher‑temperature-compatible seals to minimize accelerated wear.
