The correct method of installation hydraulic testing machine
1 trachea cut end portion deburring, trachea, can achieve a secure connection and sealing of the metal pipe joint socket.
(2) removal of the trachea, connector ferrule with the thumb pressing gently pull the trachea.hydraulic hose fittings
3 trachea repeatedly pulled out. Should be cut into the ends of the worn out portion. Shuhei successor to continue.
Four right angles, tees, crosses and other terminal metal parts. After the installation is complete, you can adjust the direction of the rotary joint body to take over the connector hydraulic banjo fittings
The joint action of the metal that is: equal to or slightly larger than the outer diameter of the metal tube at the junction, so the space is small, the bonding strength of the connection can reach the yield strength of a metal material of the two metals weak to withstand the internal pressure reaches 80 kg hydraulic or 60 kg of pressure; manufacturing process is simple and high reliability.hydraulic hose assembly
