HOSES AND SEAMLESS STEEL TUBES
High Pressure Hydraulic Hoses, as well as Marine Paint -coated Seamless Steel Tubes are recommended for transmission of oil from the Helm Pump to the Hydraulic Actuator. In small boats, High Pressure hoses will be sufficient. But in longer vessels, Marine Paint-coated Seamless Steel tubes are recommended between hoses at the Helm Pump-end and Actuator-end.
HYDRAULIC CONNECTORS
Mainly three types of connectors are used:
Banjo Connectors
Male Stud Connectors
Coupling Connectors
Banjo Connectors
A banjo fitting (also called an internally relieved bolt) comprises a perforated hollow bolt and spherical union for fluid transfer. Compared to pipe fittings that are themselves threaded, banjo fittings have the advantage that they do not have to be rotated relative to the host fitting. This avoids risk of damage by twisting the hose when screwing the fitting into place. It also allows the pipe exit direction to be adjusted relative to the fitting, then the bolt tightened independently.
Banjo Connectors
Male Stud Connectors
A Male Stud Connector comprises of 1/2" BSP Thread at one end and Nut and ferrule connector to suit Seamless steel pipes at other end.
Male Stud Connectors
Coupling Connectors
A Coupling Connector comprises of Nut and ferrule connector at both ends to suit Seamless steel pipes.
