TUBE FITTINGS

Since year 1994, VE-LOCK Tube Fittings Group is engaged in offering a variety of Threads & Ferrule Fittings as per DIN / IS / ASTM / SAE and other relevant industry standards. Our Tube fittings are interchangeable with other manufacturers sub parts which has unique advantage of using "VE-LOCK" products. All the Tube fittings are designed as per standard norms / design / drawings / dimensions which has 100% guarantee for its application.

Various “VE-LOCK” tube fitting includes the following:

Single Ferrule Bite Type Twin Ferrule Type As Per Unf Type Adaptor Fittings
SINGLE FERRULE BITE TYPE AS PER DIN 2353 -ISO 8434-1
TWIN FERRULE TYPE AS PER UNF TYPE
ADAPTOR FITTINGS AS PER BSP /NPT /UNF


Socket Weld Jic 37 0&Deg; Flare Weld Nipple
SOCKET WELD TYPE AS PER CODE 61 & 62
JIC 37 0° FLARE TYPE AS PER ISO 8434-2
WELD NIPPLE TYPE AS PER DIN 2353 -ISO -8434-4

SINGLE FERRULE BITE TYPE FITTINGS

DIN-2353
Single Ferrule Bite Type FittingsThese 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 To cater all your requirements of Hydraulic & Pneumatic application from one window, we have been manufacturing variety of Single ferrule Bite Type Fittings and couplings since last 15 years. These Single Ferrule Bite Type Fittings are available in diverse material specifications including steel and brass. We also design & supply duly assembled, complete lubrication, hydraulic and / or coolant circuits of various machines at most economical prices.

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.

Weld Fitting

All coupling in this catalogue can however be supplied with our extremely reliable O-ring welding cones which has been specially designed to easily fit into the cone. The standard coupling nut can be used.

Standards & Specifications Material Used

The wide range of couplings and Single Ferrule Bite Type Fittings are manufactured in Steel, Stainless Steel 304/316 & Brass. O-ring supplied with the fitting is made of NBR (e.g. Perbunan) having shore hardness of 90º + 5º & temperature range of -35º up to +100º C.FPM (e.g. Viton -25º up to +200º C) can also be supplied on request.

Working Principle

Installation Data SheetWhen 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 1, 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 2 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. 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 Couling Nut.

Weld Nipple Fitting

TECHNICAL DESCRIPTION FOR WELD NIPPLE FITTINGS
Weld Nipple fittings Principle :-
weld nipple fittings with an O-ring seal between weld nipple and fitting body give impressive tear out resistance and sealing integrity.

Weld nipples SKA conform with DIN 3865 form A.

Fitting bodies and nuts are fully interchangeable for weld nipple and for 2/progressive ring fittings of the same series and external tube diameter.

Materials and surface protection:
Steel phosphated and oiled, O-ring of NBR (e.g. Perbunan).
Stainless steel 1.4571, O-ring of FPM (e.g. Viton)

Welding suitability and weldability
Weld nipples, tube bend weld nipples and ASK types made of steel are weldable according. to usual techniques. Types made of 1.4571 (stainless) are suitable for arc welding. The welding filler should be selected in accordance with DIN 8556 part 1 with consideration of the type of application and the welding technique.

Tube recommendation
We recommend the use of tubes in steel and stainless steel as illustrated in this catalogue.

Nominal Pressure (PN) of complete weld nipple fittings
The nominal working pressure (PN) of a complete weld nipple fitting is dependant upon the least rated component, i.e. tube, weld nipple or fitting. The component out of these three with the lowest rated pressure or working pressure determines the nominal pressure (PN) of the complete fitting.
Permissible temperature range
For weld nipples, tube bends with weld nipples and ASK types of steel with O-rings of
1. NBR (e.g. Perbunan): –35°C to + 100°C
2. FPM (e.g.viton): –25°C to + 200°C

without pressure reductions
For temperature range and necessary pressure reductions for weld nipples, weld nipple fittings and ASK types of 1.4571, see corresponding page.

Fitting assembly
1. Cut off the tube square, deburr and bevel the end of the tube in conformance with DIN 2559.
2. Slide nut onto the weld nipple.
3. Weld nipple to the tube according to normal welding procedure. The tube and nipple must be aligned.
Before welding, please remove the nut.
4. Dress the weld on the inside and outside.
5. Fit the O-ring without twisting. The taper, the nut and the cone must all be clean.
6. Oil the nut, taper and cone and thread before assembly
7. Screw on the nut by hand. Fully tighten using a spanner with 1/4 to 1/2 turns.
Make sure that the tube with the weld nipple is assembled straight and without in built stress.
