Interlock Hose Fittings
Interlock hose fittings are designed for the heavy duty pressure, high temperature and large bore wire spiral hoses, it the strongest connection between with the crimped interlock ferrule fittings and six wire spiral skive hose. Interlock swage fitting can lock and seal of interlock hydraulic hose assembly, the connections type is from the various tube or stud connections to interlock hose ends.
Interlock hydraulic fitting Standard and Types:
Hydraulic Hose Types of Interlock Fittings
ISO 3862 type R13, EN 856 R13 and SAE J517 100R13 hoses are with a high-pressure rating having a multiple steel wire spiral.
ISO 3862 type R15 and SAE J517 100R15 hoses are heavy duty high temperature hoses with an extra high-pressure rating having a multiple steel wire spiral.
Tube or Stud Connections of Interlock Fittings
ISO 12151-1 Standard of O-ring face seal hose connector SAE ORFS
ISO 12151-2 Standard of 24 degree hose connector DIN
ISO 12151-3 Standard of four bolt flange head hose connector SAE J518
ISO 12151-5 Standard of 37 degree flare hose connector JIC
ISO 12151-6 Standard of 60 degree cone hose connector BSP
Assembling Interlock Fittings
1. Prepare Interlock fittings including separate socket and nipple, hydraulic hoses.
2. Cut off the length of hose
3. skive the hose cover and the inner tube of the hose
4. Assemble the nipple and socket and hose and crimped
5. Crimping correctly: the one tooth of socket at the shoulder end will tightly press the steel wire reinforcement layer of the hose that had been skived inner tube on the groove of nipple, form a strong anti-pulling force. Other teeth of the socket will crimp on the hose with inner tube to the nipple tail and keep sealing under higher pressure and temperature.
Application of Interlock Hydraulic Hose Assembly
Those interlock hose assemblies are used under very high pulsating pressure conditions such as hydraulic excavator, rotary drill rig etc.
Catalog of Interlock Fittings and Ferrules
Interlock ferrules series part no. is 00621 and matched hose tail series part no. is xxxx3-xx-xx. interlock hose fittings are made of carbon steel or stainless steel, for nominal hose inside diameters of 32 mm to 51 mm, inclusive.
