Principles

The BAX-LOK twin ferrule fitting consists of four precision engineered parts designed to provide secure leak- proof joints capable of satisfying high pressure, vacuum and vibration applications.

Fittings are supplied complete and ready for use. The front ferrule swages onto the tube as it moves down the cone of the body creating a pressure/vacuum-tight seal on both tube and body by the interface pressure and surface finish of mating components. The back ferrule then deforms inwards in the cone of the front ferrule, forming into the tube and creating a strong mechanical hold on the tube.

The internal diameter of the body and nut are closely controlled diameters which constrain the tube within a close tolerance of its axis ensuring accurate alignment within the assembled fittings

No distortion

Sealing

BAX-LOK tube fittings do not twist the tube during installation. The BAX-LOK fitting design ensures that all make and remake loading is transmitted axially to the tube.  Fitting make-up is eased due to a silver plating of the tube nut threads, which acts as an effective lubricant and prevents galling.

In make-up, there is no undue force in an outward direction to distort the fitting body or ferrules to cause interference between the ferrules and the nut. This assures that the nut will back off for disassembly and permits a greater number of end remarks.
Positive, reliable connections with BAX-LOK fittings have been qualified with exhaustive tests and over years of experience in the manufacture of quality tube fittings. Specific product features such as burnished cones for superior sealing and exacting manufacturing tolerances for consistent product quality, all contribute to the effective sealing of the fittings. In tests, after repeated remakes BAX-LOK fittings effected a Helium seal at over 200 bar. Vibration and impulse tests in the multi-million cycle range prove outstanding sealing capability and fatigue resistance.


HOW TO IDENTIFY METRIC FITTINGS

Metric tube fittings are identified by a stepped shoulder on both the body and the threaded end of the nut as illustrated.

Selection

The BAX-LOK twin ferrule tube fitting is precision engineered to exacting standards. Careful selection of high quality tubing together with the appropriate BAX-LOK fitting will ensure the installation of safe, leak free systems. The following tables are intended as a guide to tube ordering. The tube sizes listed are regularly tested to bursting pressure in both maximum and minimum wall thickness using correctly assembled BAX-LOK tube fittings, with no sign of leakage or failure at the connections.  For use with tubes of wall thickness other than those listed, recommendations regarding working pressures for BAX-LOK fittings can be obtained from our Technical Dept.

Tube should be fully annealed high quality stainless steel tubing to ASTM A-269 or equivalent. The preferred hardness is Rb 80 or less, if harder tube is used Rb 90 is the maximum allowed under ASTM A-269.

BSP threads

BSPP and BSP Taper threads have a thread angle of 55o.
The spot face surface must be square to the pitch diameter and free from longitudinal and spiral tool marks.

BSPP – British Standard Pipe Parallel threads are used in tubes and fittings where pressure-tight joints are not made on the thread, i.e. a peripheral seal is used.

BSP Taper – British Standard Pipe Taper threads are used in tubes and fittings where pressure-tight joints are made on the threads.

Thread Standards:
BSPP thread to: ISO 228-1, BS2779, DIN 3852 part 2,
BSP Taper thread to: ISO 7/1, BS21


 

 

 

 

 

Sealing


Interference sealing of taper threads

Pressure-tight joints of screwed connections with taper threads are achieved by the application of a sealant to the surface of the external male thread.
A minimum of five layers of PTFE tape should be wound around the external taper thread prior to the assembly.
Starting with the first thread, wrap the tape in the direction of the thread spiral.
Ensure that the PTFE tape does not overhang the first thread. PTFE tape should be to the BS4375 specification

Sealing compounds and liquid sealants.

Apart from polymer joint compounds and air-drying liquid sealants, the most common thread seal is an anaerobic synthetic resin, which cures in the absence of air.

Connections are normally ready for operation following one hour curing time, complete curing may take up to 24 hours.

Peripheral sealing of parallel threads

Pressure-tight joints of screwed connections with parallel threads are achieved by placing a seal between the two-machined faces.

Flat seal

Washers and rings are manufactured in many different materials including fully annealed 316 stainless steel, copper, aluminum, fiber, and plastics.

The tightening torque at assembly will vary according to the tensile strength of the fitting material, and the elasticity of the peripheral seal. The torque should be carefully selected to avoid compressing soft seals to the point of extrusion.

Bonded seals

Elastomer sealing rings bonded into metal washers. Bonded seals are reusable, and cater for a variation in the quality of the machined surfaces.

Installation

Interference sealing of taper threads

BAX-LOK tube fittings are supplied completely assembled.

Normal uses

1-Ensure that the end of the tube is cut square and any burrs removed without causing undue chamfering of the tube end.
2-Insert the tube into the BAX –LOK fitting ensuring that the tube is firmly butted home into the body of the fitting and the nut is finger tight.
3-With the body firmly held, mark the nut in the finger tightened position, and rotate the nut one and a quarter turns from the marked position (fig.1). The correctly made connection is then completed.
4-For sizes up to 3/16” tube fittings, only three quarters of a turn from finger tight is necessary.

High pressure applications, high safety factor systems

To allow for possible tolerance variations in tube diameters when the application demands the maximum pressure sealing capabilities of the fitting, it is recommended that the nut is tightened until the tube cannot be rotated by hand. From this point the nut should be tightened one and a quarter turns.

Re-tightening and dis-assembly
With BAX -LOK tube fittings the connection can be disconnected and retightened many times and the same reliable, safe, leak proof connection obtained.

Pre Assembly

For applications where lack of space precludes normal assembly a set of hardened pre-assembly tools is available to enable the nut and ferrules to be pre-assembled onto the tube. With the assembly tool secured in a vice, insert the tube and assemble (fig. 4) as per installation instructions.

Break the pre-assembled joint and insert this assembly into the fitting body (fig 5). Re-assemble as stated in the re-tightening instructions

What You Need to Know About LET-LOK Tube Fittings

The HAM-LET Group has been producing its superior, leak-tight LET-LOK® tubing for every kind of system since 1950. Today, the group still leads the market with its brand, which is the most advanced leak-tight tube fitting system available that meets the ever-increasing demand for such fittings especially for industrial standard mechanisms in high-performance, high-pressure and vacuum settings — such as electronics, petrochemicals, fluids, nuclear, power, and other important industrial applications.

LET-LOK® the Leading Brand

The LET-LOK® brand is the ultimate solution for a wide range of industrial applications as they are available in different types of materials. They are also customized to endure high-pressure and severe environments and are the widest range of hi-tech, state-of-the-art industrial-standard mechanisms that efficiently seal and grip tubing. LET-LOK® systems are the result of more than 50 years of energy and time poured in by industry experts in their research, design, development and manufacture.

The Workings of LET-LOK®

LET-LOK® connectors are also very easy to assemble and use. One simply inserts the tube into the full assembly till the tube bottoms-out against the fitting body. The mechanical force resulting from turning the nut clockwise, drives the two ferrules forward between the nut and the fitting body. The back ferrule is then pushed against the front ferrule’s tapered rear and the front ferrule is forced into the tapered mouth of the body. The rear ferrule is then swaged outwardly inwards on the tube while lifting the front ferrule out in order to form a full-faced seal on the tapered surface of the body. Lastly, the 3/4 and 11/4 turn (depending on the size) of the nut from the hand-tight position, ensures tight-proof drive of all the sealing components. This provides additional assurance that the seal will endure high vacuum and high-pressure conditions.

HAM-LET’s Guarantee

The HAM-LET group provides views providing clients with safety as essential. Every LET-LOK® connector has undergone, and passed, serious tolerance tests, including those for vacuum, vibration, temperature, impulse, and high-pressure. Every fitting is also manufactured according to extremely rigorous standards with advanced computerized mechanization and have proved their durability in withstanding all vigorous environments. Additionally, their ability to remain leak-tight resides in their geometry and mechanical advantage.

Clients are provided with a great deal of information and guidelines to ensure they choose the correct LET-LOK® connector for their application. This further ensures supreme and safe outcomes. It is not only important to select connectors consistent with application requirements, but to install, operate and maintain them correctly. For personal safety one also needs to choose a connector whilst considering application details, product ratings, and material compatibility. A good example is that clients in the gas industry are strongly advised to choose tubing with greater wall thickness for added safety and efficiency.

HAM-LET provides clients with the assurance that all LET-LOK® fittings were created by the most skilled craftsmen according to the highest quality-control standards for their safety and guaranteed satisfaction.
