TUBE 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).

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).

Instrument Tubing Selection Guide

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. A purchase order meeting the above criteria would read as follows:

• "1/2" x .049 316 stainless steel , seamless,or welded and redrawn per ASTM A-249.
• Fully annealed,80Rb or less. Must be suitable for bending; surface scratches and imperfections (incomplete weld seams) are not permissible."

TECHNICAL DATA SHEET FOR ADAPTOR 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.

Features

• Specially suited for thin and medium wall thickness tube
• Designed to meet the strict requirements of SAE J514 and ISO 8434-2 industry standards.

The VE-LOCK (JIC 37 Flare Fitting) design is simple. It uses an easily produced flare at the tube end to seal and hold fluid under high pressure. The fitting consists of three pieces : the body, sleeve and nut. The tube end is flared at a 37 ° angle (74 0 include angle) and held between the fitting nose (seat) and the sleeve (support) with the nut as shown in Fig.C2,providing a very effective (single) seal between the fitting nose and the tube flare.

The JIC 37 Flare Fitting incorporates the smallest seal area of all fitting types. Seal area, as seen in Fig C2, is only slightly larger than the fluid flow area. The small seal area results in a compact design, low assembly torque, and a relatively high-pressure capability.

The primary difference between a two -piece flare fitting and the three - piece design is the flare support sleeve. The support sleeve provides several key functions:

1. It provides a clamping surface for the tube flare.
2. It provides a bearing surface for the tube nut. The sleeve isolates the tube form the nut, minimizing the tube twist during assembly,a common problem of 2-piece flare fitting designs.
3. It provides support to the tube flare. The tapered fitting nose tends to "wedge open"the tube flare during assembly. The sleeve helps to resist this expansion,thus eliminating the possibility of tube flare and sleeve jamming inside the nut. This eliminates any waste of applied torque and allow for easy disassembly.
4. It makes the JIC 37 Flare Fitting adaptable to metric tube merely by changing its inside diameter (see Table C2)

The VE-LOCK Male Flare End is attachable to either inch tube, metric tube or a hose assembly. The range offers many different port thread options for the various international hydraulic ports. This is one of the primary reasons for its worldwide acceptance. VE-LOCK has traditionally offered a "Metric flared product line directed at the Metric. ISO - 6149 and BSPP Port users. Rather than carrying a separate catalog section, this range of international fitting has been integrated.

To illustrate the versatility of VE-LOCK refer to Fig.C3, A single JIC 37 Flare Fittings body will accept both inch and metric tube sizes by simply changing the sleeve. Thus, a dedicated line of sleeves is offered for inch and metric tube. The universal tube nut and fitting body is used with either inch or metric tube, thus saving on component coast and making the VE-LOCK fitting more versatile. Also, the 37 ° body without the nut and sleeve is very popular as a hose Adaptor.

Study the following example illustrating the options with an SAE -8 (1/2") VE-LOCK fitting:

1. Fitting with a -8 (1/2") sleeve and -8(1/2") tube nut can connected to a 1/2" o.d. flared tube.
2. Fitting with a 12 mm sleeve and -8 (1/2") tube nut can connected to a 12 mm o.d. flared tube.
3. Fitting without a nut and sleeve can be used as a 1/2" hose Adaptor when connected to a hose swivel.
