BAX-LOK DOUBLE FERRULE INSTRUMENT FITTINGS
Hy-Lok needle valves offer secure, leak-free connections and provide the lowest overall cost of any instrument needle valve used in the market today.
Needle valves within a block and bleed function help achieve positive isolation within maintenance operations of a live process plant. These work well in non-critical processes like with non-hazardous fluids or a low pressure system.
The small port and needle-shaped, threaded plunger allows for precise flow regulation in low flow applications. Not only for maintenance, needle valves also work well in flow-metering operations, and are especially good at maintaining a calibrated and constant low flow rate.
Rugged and compactly designed, Hy-Lok offers a wide range of sizes (1/8″ to 1″), and stem tips (v-stem, regulating, and soft seat) that work well for a variety of applications, including hydraulic and pneumatic systems. Of 316 stainless steel as standard, and some as alloy 400, Hy-Lok needle valves are meticulously designed for the flow, temperature and system required.

Specifications
– Maximum Operating Pressure :

– Operating Temperature Range :
-325℉(-198℃) to 1200℉(648℃)
Two ferrule tube fittings are designed and manufactured to meet the rigorous specifications required of industrial applications. Hy-Lok tube fittings are commonly used throughout the oil and gas, pulp & paper, petro-chemical/chemical processing, research laboratories, aerospace and defense, chemical processing, power generation, cryogenic and semiconductor, shipbuilding and heavy industrial industries.
Available in numerous configurations and sizes, our tube fittings are made up of four parts consisting of a body, front ferrule, back ferrule, and nut. Outstanding leak-tight connections are consistent as the two-ferrule design compensates for any tolerances in tube outer diameter, wall, thickness, and material hardness.
Hy-Lok tube fittings feature a low torque assembly and positive leak free seal for easy assembly and reassembly. During installation the mechanical properties of the tubing are maintained because the back ferrule moves in a controlled manner that does not stress or reduce the inner diameter of the tubing. Since the front ferrule does not force the body to expand the nut can be backed off easily for disassembly and remakes.
Constructed of standard materials including 316 stainless steel, brass, and Monel, other materials such as duplex stainless steel, titanium, and carbon steel are available upon request. Heat code traceability for 316 stainless steel and Alloy 400 assures the ratings and quality of each fitting and accounts for code requirements.
Fitting size range from 1/16″ thru 2″ (2 mm thru 38 mm O.D.tubing) with numerous choices in end connections and patterns. They are rated to the maximum working pressure of the recommended tubing. Hydraulic swaging tools (EZY-MAT) are provided for easy installation.
Hy-Lok tube fittings are manufactured to Hy-Lok’s stringent quality control program and standards which assure the highest quality available in the industry. We are a global industry leading provider of fitting solutions and have obtained ASME Quality and ISO 9001:2008 Certifications.
To fulfill the need for leak-free gas and fluid containment, our tube fittings are the ideal solution.
