3 These two ferrule fittings are manufactured to the high test quality standards & available in a large of sizes, materials and configurations. Tubefit Engineers Tube Fittings has been designed for use in instrumentations, process & control system, analyses and environment employed in chemical, petroleum, power generating, pulp & paper plants. Tubefit Engineers tube Fitting has also found special application in other fields where high pressure tube Fitting has also found special application in other fields where high pressure tube fittings are required. If more specific information, including heat code traceability, is required Tubefit Engineers will provide details. Stainless steel Tubefit Engineers tube fittings work reliably on both seamless & welded - redrawn, fully, annealed type 304, 306 & 316L tubing. Tubefit Engineers Tube Fittings are available as standard in Heat Code Traceable, SS316, SS316L, SS304, Carbon Steel, Brass, Monel, Hastalloy.

4 Straight fittings are machined from cold finished bar stock & shaped bodies are machined from high quality forging. The Row materials used fully conforming to chemical requirements as per respective material specifications. Tube Fitting have been designed and manufactured with great care to meet the specifications required for wide range of applications in chemical, petro chemical, oil refinery, power generation, shipbuilding, pulp & paper, micro electronics, etc. The double ferrule Fitting consists of four parts body, front ferrule, back ferrule & nut. This two ferrule design consists of front & back compensates for any tolerances in tube OD , wall thickness, material hardness & always secure leak proof joints capable of high pressure, vacuum & vibration applications. Allows the front ferrule to seal while the back ferrule grips.

5 Uses consistent geometry (instead of torque) for gauge able make-up. Overcomes variations in tube materials, wall thickness & hardness. Provides excellent vibration resistance. Allows reliable remake connections. Easy to install using hand tools. No torque is transmitted to tubing during installation. Gap inspection gauge assures sufficient pull-up upon initial installation. Installation instructions are available (see page ).Excellent gas-tight sealing and tube-gripping action. Reduced potential for improper pull-up. Consistent remakes. Excellent vibration fatigue resistance and tube support. Full compatibility with original stainless steel tube fittings & front ferrules of identical sizes. Easy installation. Gauge ability on initial installation using gap inspection gauges Shaped fittings, such as elbows, crosses, & tees, have a stepped shoulder on the body & nut hex.

Straight Fitting are machined from cold finished bar stock & forging. Specifications for Fitting materials & tubing are shown below. For special applications, contact TUBEFIT ENGINEERS. Tubefit Engineers Tube Fittings can be used with a wide Varity of tubing materials & a large of tube wall tube fittings are available as a standard O-ringsPlating & CoatingSafety PrecautionsTubing considerations O-seal fittings include a 70 durometer Buna O-ring.

7 Other straight thread fittings with O-rings include a 90 durometer fluorocarbon FKM O-ring. Other O-ring materials are available upon request. O-rings are coated with a thin film of silicone-based lubricant. Removal of factory applied lubricants may alter fittings are rated to 3000 psig (206 bar). For improved performance, Fitting components receive additional processing. Fitting bodies that are subjected to further processing (plating and coating) are shown. Over 1 in. and over 25 mm stainless steel fittings use stainless steel ferrules with PFA coating. Applications above 450 F (232 C) require silver-plated front ferrules & uncoated back ferrules. To order fittings with silver-platedferrules, add -BM as a suffix to the basic ordering number. All carbon steel Swagelok tube fittings are supplied with 316 stainless steel back Use only long reducers in female Never allow problems to go Avoid unnecessary disassembly of unused Do not bleed system by loosening Fitting nut or Fitting Never turn Fitting body.

8 Instead, hold Fitting body & turn nut. v Always use proper thread sealants on tapered pipe Do not make up and tighten fittings when system is pressurized. v Use gap inspection gauge to ensure sufficient pull-up upon initial Do not mix materials or tubing, ferrules, nuts & Fitting bodies from various Make sure that the tubing rests firmly on the shoulder of the tube Fitting body before tightening the Metal tubing material should be softer than Fitting material. For example, stainless steel tubing should not be used with brass fittings. v When tubing and fittings are made of the same material, tubing must be fully annealed. v Always use an insert with extremely soft or pliable plastic tubing. v Extremes of wall thickness should always be checked against Fitting manufacturer s suggested minimum & maximum wall thickness limitations.

9 V Surface finish is very important to proper sealing. Tubing with any kind of depression, scratch, raised portion, or other surface defect will be difficult to seal, particularly in gas Tubing that is oval & will not easily fit through Fitting nuts, ferrules & bodies should never be forced into the & CoatingMaterials StandardsMaterialStainless Steel(Type 316)Carbon SteelBrassAluminiumHastelloy C-276 Alloy 20 Alloy 400/R-405 Alloy 600 TitaniumNylonPTFESAF 2507 Bar StockASTM A276 ASME SA479 ASTM A108 ASTM B16 ASTM B453 ASTM B211 ASTM B574 ASTM B473 ASTM B164 ASME SB164 ASTM B166 ASME SB166 ASTM B348 ASTM D4066 ASTM D1710 ASTM A479 ForgingASTM A182 ASME SA182 ASTM B283 ASTM B247 ASTM B564 ASTM B462 ASTM B564 ASME SB564 ASTM B564 ASME SB564 ASTM B381 ASTM D3294 ASTM A182 Common TubingSpecificationASTM A213 ASME SA213 ASTM B 75 ASME SB 75 ASTM B622/626 ASTM B 163 ASTM B 338 Fitting MaterialAluminumAlloy 400/R-405, Alloy 20,Alloy C-276, Alloy 600 Carbon Steel(except weld bodies)Carbon Steel(welded bodies)

We believe that interchanging & intermixing tube Fitting components of different designs, made by different manufacturers, can result in leaks & tube slippage in a percentage of cases. We also believe this practice can be dangerous in critical applications. Leak-tight seals that will withstand high pressure, vibration, vacuum & temperature changes depend upon close tolerances & consistent, exacting quality control in conjunction with good design principles. The full value we build into tube fittings is lost when components from other manufacturers are interchanged or intermixed with ours.
