Single Ferrule Design - DIN 2353
These Single Ferrule Bite Type Fittings are the most widely used bite type fittings
in the world. These Single Ferrule Bite Type Fittings are flareless bite type metric
fittings that consists of a body, progressive ring (ferrule) and nut. On assembly,
two cutting edges of the ferrule “bite” into the outer surface of the tube ensuring
the necessary holding power for high operating pressures.
Features
:: These Single Ferrule Bite Type fittings and accessories (Three Series)are
manufactured in accordance with DIN 2353 for fluid application
:: The three components of Single Ferrule Bite Type Fittings are designed
to produce a strong, reliable, leak-free joint upon proper assembly
:: Couplings are best suited for steel, copper or stainless steel tubes where
brazing, soldering, welding, flaring or threading is not possible or permissible
Working Principle
Single Ferrule Bite Type Fitting is a flare less three-piece design fitting comprising
of a Socket body having a precision conical seat, a one-piece precision machined
hardened Progressive Ring (ferrule) and a Coupling Nut. When the Coupling Nut is
progressively tightened it makes the Progressive Ring to move on to the tube which
subsequently makes two bites into the outside diameter of the pipe, thereby forming
a visible collar of material at A, ensuring a strong, reliable, high degree of safety
and permanent sealing due to the outstanding construction & design of our progressive
ring.
A second seal point at B is also created between the now bowed ferrule and the fitting
body seat. The progressive ring in its dismantled state can be turned around while
still on the tube.

Twin Ferrule Bite Type Fittings
Twin Ferrule Bite Type Fittings are sold completely assembled and ready for immediate
use. Simply insert the tube as illustrated until it bottoms in the fitting body.
(If the fitting is dis-assembled, note that the small tapered end of the ferrule
(s) go into the fittings body).
Method :
Simply place the nut on the thread and rotate. Tighten the nut using wrench with
1 - 1/4 turns as indicated below. Hold the fitting body with a second wrench to
prevent it from turning. It is helpful to mark the nut to facilitate counting the
number of turns For maximum number of remakes, mark the fitting and nut before disassembly.
Before retightening, make sure the assembly has been inserted into the fitting until
the ferrule seats in the fitting. Retighten the nut by hand. Rotate the nut with
a wrench to the orginal position as indicated by the previous marks lining up. (A
noticeable increase in mechanical resistance will be felt indicating the ferrule
is being re - sprung into sealing posistion. Only after several remakes will it
become necessary to advance the nut slightly past the original position. This advance
(indicated by B) need only be 100 - 200(less than 1/3 of a hex flat).
Tubing Ordering Suggestions
Tubing for use with Ve - Lock instrument fitting must be carefully ordered
to insure adequate quality for good performance. Each purchase order must specify
the material nominal outside diameter, and wall thickness. Ordering to ASTM specifications
insure that the tubing will be dimensionally, physically and chemically within strict
limits. Also more stringent requirements may be added by the user. All tubing should
be completely free of scratches and suitable for bending.

JIC 37 Degree Flare Fittings
 Ve-Lock
represents the JIC 37 Flare Fitting concept since year 1994 and the design has since
gained worldwide acceptance due to its many inherent features and customer benefits.
Today,the JIC 37 Flare Fitting is the most widely used fitting in the world. Its
appeal is in its simplicity, compact design, ease of assembly, reliability (single
seal), material availability, adaptability to inch or metric tube, worldwide availability
and acceptance. Further helping its acceptance is its widespread use as a hose Adaptor.
Even though JIC 37 Flare Fittings are generally considered to be 3000 psi fittings,
Ve-Lock's capabilities range from 9000 psi for 1/4" size to 2000 psi for 2" size.
Currently,it is used in virtually every application that uses fluid power for motion
control.
