Can the Screwed connector with GW NPT without valve, carbon steel, type HPA be connected/disconnected under residual system pressure up to 700 bar?

Yes. The Screwed connector with GW NPT without valve, carbon steel, type HPA can be connected and disconnected under residual system pressure up to 700 bar. The product is designed for very high-pressure installations and explicitly states it "can be connected/disconnected when there is residual pressure in the system." Its maximum working pressure is 700 bar; burst and disconnected-plug ratings (1/4" disconnected plug 1490 bar, 3/8" disconnected plug 1500 bar) indicate safety margins above that working pressure. Ensure correct size, proper sealing (NBR), compatible end caps (ordered separately), and adherence to operating temperature range (â25Â°C to +100Â°C) and application-specific safety procedures.

Can the Screwed connector with GW NPT without valve, carbon steel, type HPA withstand repeated mechanical shocks at 700 bar?

Yes. The Screwed connector with GW NPT without valve, carbon steel, type HPA is designed for very high-pressure, high-mechanical-load installations and specifies a working pressure of 700 bar. Its burst pressures when connected (2100 bar for 1/4", 1850 bar for 3/8") and when disconnected (1490 bar for 1/4", 1500 bar for 3/8") indicate substantial safety margins above 700 bar. Materials (carbon steel) and NBR sealing are suitable for heavy-duty use and specified operating temperatures (-25Â°C to +100Â°C). Therefore, it can withstand repeated mechanical shocks at 700 bar, provided installation follows manufacturer guidelines, end caps are used, and shocks do not exceed tested burst/connector fatigue limits or introduce damaging anomalies (misuse, corrosion, extreme temperatures).

Is the Screwed connector with GW NPT without valve, carbon steel, type HPA suitable for rescue equipment use at 700 bar?

Yes. the Screwed connector with GW NPT without valve, carbon steel, type HPA is suitable for rescue equipment use at 700 bar. The product is explicitly designed for very high-pressure hydraulic installations and lists rescue equipment among intended applications. Its working pressure is 700 bar, burst pressures when connected (1/4" = 2100 bar, 3/8" = 1850 bar) provide substantial safety margin, and it allows connection/disconnection under residual pressure. a practical feature for rescue operations. Materials and sealing (carbon steel, NBR) and operating temperature range (â25Â°C to +100Â°C) are appropriate for typical rescue environments. Ensure correct size (flow rates given) and order end caps separately. Verify compatibility with your specific system standards, fittings, and any regulatory or certification requirements for rescue equipment in your jurisdiction.
