Screwed quick-connector, plug with METRIC FG (DIN 2353, light series), in galvanized steel, type HS

Q: Can the Screwed quick-connector, plug with METRIC FG (DIN 2353, light series), in galvanized steel, type HS be tightened under residual pressure up to 50 bar?

Yes. Screwed quick-connector, plug with METRIC FG (DIN 2353, light series), in galvanized steel, type HS can be tightened under residual pressure up to 50 bar. The product description explicitly permits tightening under residual pressure up to 50 bar; it is designed for hydraulic oil, uses galvanized steel construction with NBR sealing (â25Â°C to +100Â°C), and has working pressures up to 450 bar (size-dependent) with a 4:1 safety factor.

Q: What is the maximum operating temperature for the Screwed quick-connector, plug with METRIC FG (DIN 2353, light series), in galvanized steel, type HS?

The maximum operating temperature for the Screwed quick-connector, plug with METRIC FG (DIN 2353, light series), in galvanized steel, type HS is +100Â°C.

Q: Does the Screwed quick-connector, plug with METRIC FG (DIN 2353, light series), in galvanized steel, type HS use NBR seals suitable for hydraulic oil?

Yes. The Screwed quick-connector, plug with METRIC FG (DIN 2353, light series), in galvanized steel, type HS uses NBR seals and is specified for hydraulic power (hydraulic oil). The description states socket sealing: NBR (operating temperature â25Â°C to +100Â°C) and lists application as hydraulic oil, so the NBR seals are suitable for use with hydraulic oil within the given temperature range. Ensure compatibility with your specific hydraulic fluid and operating temperature/pressure conditions (working pressure up to 450 bar, permitted tightening under residual pressure up to 50 bar).
