high quality and reliable sealing performance.

3 Introduction lokdj Compression Fittings are the products developed and manufactured by Tachia Yung Ho Machine Industry Co., Ltd, carrying quality brand name. It is a reliable and leakage free conjunction system offering quick connection, repeatable use of tubing components, variety of selection of the connection type for converting one system to another, high quality and reliable sealing performance. Technical Specifications The lokdj Compression Fittings is designed having four precision machined parts offering a leakproof and quick on site setup performance for meeting the requirement in the application of high pressure vacuum and vibration working environment. 4 lokdj back ferrule is harden heat treatment 2 lokdj fitting body Specific name as below is introduced and explained for your reference. Manufacturer:Tachia Yung Ho Machine Industry Co., Ltd. (Taiwan) :Brand name of the product manufactured by Ultra High Purity Business Division (UHP) lokdj :Instrumentation fittings product, promoted by brand, manufactured by Tachia Yung Ho Machine Industry Co., Ltd. Flexibility In Connection: lokdj Compression Fittings offer a variety of selection for converting one piping system to another as below. clamping point 2 silver plated hexnut prevent gall while tightening 3 lokdj front ferrule offers pressure sealing effect clamping point tube is placed by touching to the wall of lokdj fitting body lok type union to lok type union conjunction lok type union to thread type conjunction lok type union to buttwelding type conjunction (upon request) lok type union to ISOCF flange (upon request) lok type union to Face Seal system fittings (upon request) Clamping poing 2 Clamping poing The lokdj Compression Fittings consist four precision machined parts as below. These twoferrules are designed to perform clamping and sealing by a compression effect on the pipe with main body of the lokdj. It is named two ferrules type or compression instrumentation fittings.

Assembly lokdj. lokdj Compression Fittings are manufactured and ready for immediate use. To insert the straight tube into lokdj fitting body until it has contacted the bottom of lokdj fitting body. 2.

Then, one spanner can be used to hold lokdj hex nut on fitting body in position against another spanner holding on freehex nut. 4.

For to, turns from finger tight is necessary. Primary Material lokdj Compression Fittings uses Type 3 stainless steel carrying international standard code of ASME SA479 and ASMESA2.

All products are documented with chemical composition, mechanical property and heat number for quality traceable availability.

4 Assembly lokdj. lokdj Compression Fittings are manufactured and ready for immediate use. To insert the straight tube into lokdj fitting body until it has contacted the bottom of lokdj fitting body. 2.To tighten the lokdj fitting body through two nuts by finger firstly. 3. It is suggested to mark a reference line on nut and lokdj fitting body for helping counting the number of the turns. Then, one spanner can be used to hold lokdj hex nut on fitting body in position against another spanner holding on freehex nut. 4. The second spanner can turn freehex nut additionally turns to tighten whole set of lokdj fitting. For / to 3/ lok DJ, only turn from finger tight in necessary. For to, turns from finger tight is necessary. Primary Material lokdj Compression Fittings uses Type 3 stainless steel carrying international standard code of ASME SA479 and ASMESA2. lokdj Compression Instrumentation Fittings are manufactured in accordance to ISO quality control system. All products are documented with chemical composition, mechanical property and heat number for quality traceable availability. Typical Raw Material Specifications Basic Fitting Material Stainless Steel (Type 3) Bar Stock ASMESA479, Type 3SS BS970 3S3 Din 440 Forging ASMESA2 3 BS970 3S3 DIN 440 Compatible Tubing Specification ASMESA23 ASTMA23 ASTMA249 ASTMA29 ASTMA270 MIL T504 MIL T50 Remake lokdj.lokdj fitting can be disconnected and rebuilt repeatedly for several times without loss of its leaktight performace. Before disassembly, a reference line mark can be made across of the Nut and the Fitting Body. 2. After completion of disassembly of the lokdj fittings, the Nut and two Ferrules are seated on tubing. 3. To remake the assembly, it can preassemble the Nut with the Fitting Body by fingers. Then, to use wrenches to tighten the Nut and Fitting Body to the position where line marks meet to each other. 4. A slightly rise in torque can be applied on wrenches to tighten the Nut and Fitting Body. How to Order lokdj Compression Fittings Example: RU4B(For ) RU Reducing Union Fractional tube end dimension is OD 4 Fractional tube end dimension is OD 3 Stainless Steel, B: BA finish, 0Ra H H or blank: degreasing Matching Tubing lokdj Compression Fittings is fabricated by 3 stainless steel.
