Is the HOLMBURY HS Galvanized Steel Socket Quick-Connector with BSP Female Thread safe to tighten under static pressure up to 50 bar and suitable for systems up to 450 bar?

Yes. The HOLMBURY HS Galvanized Steel Socket Quick-Connector with BSP Female Thread is designed to be tightened under static pressure up to 50 bar and is rated for working pressures up to 450 bar (depending on size). It features galvanized steel construction, NBR sealing, an additional O‑ring to prevent accidental loosening under pulsation/vibration, and a 4:1 safety factor, making it suitable and safe for hydraulic oil systems within the specified pressure and temperature ranges.

Can the HOLMBURY HS Galvanized Steel Socket Quick-Connector with BSP Female Thread maintain sealing and vibration resistance in hydraulic systems operating between -25°C and +100°C?

Yes. The HOLMBURY HS Galvanized Steel Socket Quick-Connector with BSP Female Thread is specified to maintain sealing and resist vibration in hydraulic systems from -25°C to +100°C. Key features supporting this: - NBR internal seal rated for the –25°C to +100°C temperature range, providing reliable sealing across those temperatures. - Additional O-ring on the socket body to prevent accidental loosening under pulsating pressure or vibration, enhancing retention and leak resistance in dynamic environments. - Robust galvanized steel construction and a 4:1 safety factor (working pressures up to 450 bar depending on size) that ensure mechanical integrity under high-pressure and vibratory conditions. - Capability to be tightened under static pressure to 50 bar and designed for optimized flow with minimal pressure drop, supporting stable system performance. Taken together, these design elements indicate the connector will maintain seal integrity and vibration resistance within the stated temperature range when used in hydraulic oil systems and within the specified pressure limits.
