DOUBLE COMPRESSION
TUBE FITTINGS
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 ¼ turn from finger tight position. This action forces both front & 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 and 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.
• Back ferrule dampens the tube circuit mechanical vibration through spring like action, also prevent carry over tightening
torque from nut to front ferrule.
• 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.
• The nut is silver plated to avoid galling and give low assembly torque.
• No Pre-Lubrication needed, also allows repeated make and remake.
Other Features
• Flare less design.
• Available for metric and fractional (imperial inch size) tubes with choice of NPT/BSPT/BSP/SAE/ISO pipe threads.
• Wide range of sizes and configurations.
• Manufacture in wide range of material like Stainless Steel, Steel, Brass, Aluminum, Titanium, Hastalloy, Monel and
other special alloys.
• All components of fittings are made of same material.
• Excellent make and remake life.
• Interchangeable with leading international brands.
• Suitable with thin or thick walled tubes.
• Fittings are tested for high pressure, vacuum, impulse, vibration and temperature to ensure safety.

Material Specifications And Standard
ANSI B 1.20.1
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.
4
Seamless tube wall thickness (SWG/Inch)
NOTE : No allowance is made for corrosion or erosion, for welded tubing multiply above pressure rating by 0.80
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.

Safety Precautions
• Select proper tube thickness as per working pressure requirement (refer table)
• Usefully annealed tube (preferred hardness 70-74 HRB), free from scratches, surface defects
• While assembling always hold the body firmly and rotate the nut, do not turn the 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 os not pressurized
• Do not loosen the nut or pipe thread to bleed the system line
• No axial movement of ferrule after swaging is allowed

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 available 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 ½ ” Tube
x1/4'’ NPT or 3/8'’ Tubex1/4'’ NPT can not bere through.
Please add sufffix BT to order bore through fittings.
CHECK VALVES
• Check valves are available in Stainless Steel and Brass
material

QRC
(QUICK RELEASE COUPLING - PUSH & PULL TYPE)
Working Principle
QRC type coupling work on Push and Pull principle. When the
Adaptor is pushed to the coupler, its is accurately held by the self
locking arrangement resulting in a positive & leak proof
connection. This action simultaneously opens the valve & fluid
flow starts. To disconnect, pull back the sleeve of the coupler, the
Adaptor ejects out and the valves shut off automatically. Valves
are provided in type one way sealing & two way sealing.
Features
Quick connect / Release Couplings eliminate valves and screw
on fittings in many pneumatic, hydraulic and chemical systems.
Permits easy, safe, quick & reliable connections between delivery
lines, pressure hoses etc.
Connection disconnection of fluid systems is as easy as plugging
in an electric gadget.
PRESSURE GAUGE
ACCESSORIES
Siphon (Pig type, Ring type, U type) Gauge cock (2 way, 3
way), Snubber (Dampener), Gauge saver, Bleeder plug,
Pressure gauge adaptors and reducers are available in SS
316/304.
