Can the Screwed quick-connector (3/4" Ã· 1") socket in galvanized steel, type TC be tightened under residual pressure up to 50 bar safely?

Yes. The Screwed quick-connector (3/4" Ã· 1") socket in galvanized steel, type TC may be tightened under residual (static) pressure up to 50 bar safely. The product description explicitly permits tightening of the quick coupling under residual pressure up to a maximum of 50 bar. Operating limits (material, NBR seals, temperature range â40Â°C to +106Â°C, working pressure up to 350 bar and safety factor 3:1) support safe use in hydraulic oil systems of heavy-duty trucks, provided the residual pressure does not exceed 50 bar. Ensure the system is otherwise intact, fittings and seals are undamaged, and standard safety procedures are followed when tightening.

Can the Screwed quick-connector (3/4" Ã· 1") socket in galvanized steel, type TC be used in dump truck hydraulic systems at -40Â°C to +106Â°C?

Yes. The Screwed quick-connector (3/4" Ã· 1") socket in galvanized steel, type TC is specified for hydraulic systems of heavy-duty trucks (dump trucks), uses hydraulic oil, has NBR sealing and an operating temperature range of â40Â°C to +106Â°C, and supports working pressures up to 350 bar (safety factor 3:1). It also permits tightening under residual pressure up to 50 bar. Therefore it is suitable for dump truck hydraulic systems operating between â40Â°C and +106Â°C.

Is the Screwed quick-connector (3/4" Ã· 1") socket in galvanized steel, type TC suitable for hydraulic oil up to 350 bar?

Yes. The Screwed quick-connector (3/4" Ã· 1") socket in galvanized steel, type TC is suitable for hydraulic oil up to 350 bar. The product description specifies use in hydraulic power systems (hydraulic oil), construction in galvanized steel with NBR seals, and a working pressure rated up to 350 bar (depending on size). It also allows tightening under residual pressure up to 50 bar and has a safety factor of 3:1. Operating temperature range is â40Â°C to +106Â°C, appropriate for typical hydraulic oil applications.

All products, Hydraulic quick couplings/

Additional information

Material	CS – steel (cast iron)

The screw-together quick-coupling socket, type TC, for use in the hydraulic systems of dump trucks. The socket is fitted with a locknut, which allows bulkhead mounting. The quick coupling may be connected under residual pressure of max. 50 bar (static pressure remaining in the system after the drive is switched off). Application: power hydraulics (hydraulic oil). Material: galvanized steel. Sealing: NBR. Operating temperature: from -40°C to +106°C. Working pressure: up to 350 bar (depending on the size). Safety factor 3:1. The flow is given for a pressure drop of 3 bar.
