Double Compression Tube Fittings
Design & Function

Double compression (Double ferrule) tube fittings provide a leak proof, torque free joints in all instrumentation & process tubing connections which will withstand high pressure, Impulse, Vacuum, Vibration and temperature. These features eliminates costly, hazardous leaks provide highest safety and maintenance free tubing joints.

All action in the fittings move axially, i.e. Tube is not twisted during assembly. Since no torque is transmitted from the fittings to the tubing, there is no initial strain, which might weaken the tubing. Each part in the fitting assembly is machined to most exact dimensional tolerance on CNC machines. Total quality management is practiced throughout the manufacturing process as per ISO standard to achieve best quality joints at all tubing end connections. Tube fitting assembly consist of four precision machined components namely body, nut, front ferrule and back ferrule.All you need to do is to insert the tube and tighten the nut by 1 turn from finger tight position. This action forces both front as well as back ferrule to move forward between nut and body, Back ferrule is driven against the rear taper of the front ferrule and swaged radially inward on the tube,thus holding the tube against vibration and mechanical pull due to pressure. Back ferrule also lift the front ferrule out to form a full faced seal on the taper surface of the body. Front ferrule also moves forward against the taper portion of the fitting body due to wedging action forces inward, gripping and subsequently sealing the front edge tightly on to the tubing.

Design Features

  • Double ferrule fitting consists of 4 parts for leak proof maintenance free joints.

  • 1 - Back ferrule dampens the tube circuit mechanical vibration through spring like action, also prevent carry over tightening torque from nut to front ferrule.

  • 2 - The front ferrule circumferentially seals the surface between tube and the fitting body. The front edge of the ferrule is pressed on to the tube so that pressure tight impression is formed

  • 3 - The nut is silver plated to avoid galling and give low assembly torque.

  • 4 - No Pre-Lubrication needed, also allows repeated make and remake
Other Features

  • 1 - Flare less design.

  • 2 - Available for metric and fractional (imperial inch size) tubes with choice of NPT/BSPT/BSP/SAE/ISO pipe threads.

  • 3 - Wide range of sizes and configurations..

  • 4 - Manufacture in wide range of material like Stainless Steel, Steel, Brass, Aluminum, Titanium, Hastalloy, Monel and other special alloys

  • 5 - All components of fittings are made of same material

  • 5 - Excellent make and remake life.

  • 6 - Interchangeable with leading international brands.

  • 7 - Suitable with thin or thick walled tubes..
  • 8 - Fittings are tested for high pressure, vacuum, impulse, vibration and temperature to ensure safely

Identification of Fractional and Metric Tube Fittings

As there is marginal difference in nearest metric and fractional size of tubes, visually it is difficult to identify fitting tube sizes. Therefore step is provided on both body and nut for metric tube fittings as shown in following illustration.

Safety Precautions

  • Do not mix up parts from different manufactures
  • Select proper tube thickness as per working pressure requirement (refer table)
  • Usefully annealed tube (preferred hardness 70-75 RB), free from scratches,surface defects
  • While assembling always hold body firmly and rotate nut, do not turn body
  • Use proper thread sealant while assembling taper threads
  • While installing fitting near tube bends,leave sufficient straight length to allow tube to be bottomed the fitting
  • While tightening or loosening a fitting be sure that the system as not pressurized
  • Do not loosen the nut or pipe thread to bleed the system line

Pressure Rating and Tubing Selection

Double and single compression SS Tube fittings are rated to the maximum working pressure of the tubing gas shown below. Therefor proper selection of tubing must be done while making safe leak free joint. Tube should be fully annealed, high quality stainless steel tubing. The preferred hardness is Rb70 or less. The tubing should be free from scratches, surface defects and suitable for bending.

Following rating is based on annealed seamless 304 or 316 SS tubing with ultimate tensile strength 517000 kPa and allowable working pressure load of 137800 kPa.

Chromatograph Fittings :

Tube fittings in different sizes (1/16",1/8) are available for gas and liquid chromatography. They are made in different material and configuration.

Bored-Through Fittings :

BOred through fittings are used for connecting thermocouples or dip tubes. These connectors are avaliable in SS, Brass,Monel. Hastalloy, Titanium etc. the Root diameter of the pipe thread end of male connectors makes it impractical to bore through all size so female connectors, for instance 1/2 " Tube x1/4" NPT or 3/8" Tubex 1/4" NPT can not bere through. Please add suffix BT to order bore through fittings.

Heat Exchanger Tee :
Avaliable both in two piece (Union Tee and Bore through Reducer)and single piece (Reducing Tee) design.

Accessories
General Selection :-
The fluid media contained to flow inside the tubes and is compatibility with tube material play a main role. Stainless steel fittings should be used only with stainless steel tubing, Aluminum fittings with aluminium tubes etc. mixing of different materials is to be prohibited. The only exception is brass fittings with copper tubing.

Gas Service :-
Special care must be taken during selection of tubes for pressurised gas services. In order to achieve leak proof sealing between ferule and tube the tube material must be softer than ferrule so it will penetratein to tube.

System Pressure :-
The system pressure is another mechanical parameter for selection of material off tubes.In general, high pressure installations require strong materials such as steel or stainless steel. Copper may be used if chemical compatibility exists with the media.The higher strength of steel or stainless steel permits the use of thinner tubes without reducing the ultimate rating of the system.
