Hytech's Double Ferrule Tube Fittings consists of four pieces which include Nut, Back Ferrule, Front Ferrule and the Body. Upon installation with the tubing, it becomes the five-piece connection. Solid leak proof mechanical joint is formed by the attaching tube to the Double Ferrule Compression Fitting by swaging. Stainless Steel Double Ferrule Fittings are used across multiple industries such as the pulp & paper, laboratories, downstream petrochemical, aeronautical and shipbuilding as well as the defence industry
During the assembly when nut is being rotated, rotational movement of the nut is transferred to the axial movement of back ferrule by the specially designed threads of nut and body.
This axial push to the back ferrule makes front ferrule to travel further, this displacement of front ferrule is restricted by cone of fittings body making edge of front ferrule to be compressed against the tubing. Further tightening of nut ensures back ferrule creating hinge joint with the ferrule and tube. This makes tube to be compressed at two locations at the edge of front ferrule and edge of back ferrule.
This mechanical joint is a result of special designed geometry and metallurgical research done by Hytech R&D team. Hytech has optimized each component form the assembly to do intended function. Front ferrule creates seal between body and tube while the back ferrule creates the seal between front ferrule and tube. Silver coated buts ensures there would be minimum torque upon tightening.
Advantages
- • Metal to metal seal connection eliminates potential assembly errors associated with over tightening of the parts
- • Metal to metal seal allows the use of these fittings in wide temperature and pressure requirements
- • Design is standard for inch tubing from 1/8" OD to 2" OD and 3 mm to 42 mm metric tubing, Assembly instructions are also common across all sizes, this helps installers to make more reliable and consistent leak proof joint
- • Consistent make and remake feasibility
- • Excellent vibration fatigue resistance
- • These fittings can accommodate thermal cycling behaviour of atmosphere or internal media
- • Stainless steel material makes these fitting suitable for corrosive application without affecting the performance over a period of time
- • During the installation no torque is transmitted to the tubing
