2 Parker Hannifi n Corporation Instrumentation Products Division Huntsville, AL USA http://www.parker.com/ipdus Introduction Parker CPI /A-LOK Instrumentation Tube Fittings are designed as leak-free connections for process, power and instrumentation applications. These single and two ferrule fittings are manufactured to the highest quality standards and are available in a broad range of sizes, materials and configurations. Features The Parker CPI /A-LOK tube fitting has been specifically designed for use on instrumentation, process and control systems, analysers and environmental equipment employed in chemical, petroleum, power generating and pulp and paper plants. The CPI /A-LOK tube fitting has also found extensive application in other fields where a high quality tube fitting is required. Materials Parker CPI /A-LOK fittings are available as standard in Heat Code Traceable, 316 stainless steel. Other standard materials include steel, brass, aluminum, nickel-copper, Hastelloy C , Alloy 600, Titanium, 6Mo, Incoloy 625 and 825. Straight fittings are machined from cold finished bar stock and shaped bodies are machined from close grain forgings. The raw materials used fully conform to the chemical requirements listed in Specification Table 1. For nuclear and other critical applications, stainless steel CPI /A-LOK fittings are readily available with documented heat code traceability. Pipe Fittings/Adapters Parker CPI /A-LOK tube fittings are available in a wide variety of ISO and ANSI pipe thread configurations. For a full line of these fittings, see Catalog 4260. Tubing Parker CPI /A-LOK tube fittings can be used with a wide variety of tubing materials and a broad range of tube wall thicknesses. CPI /A-LOK seals equally well on both thin wall and heavy wall tubing. Tubing and fitting materials should be selected to be compatible with the fluid media. Due to thermal expansion characteristics and chemical stability, the tubing should be of the same material as the fitting. (The exception is brass fittings and copper tubing.) Torque Parker CPI /A-LOK tube fittings do not twist the tubing during installation. CPI /A-LOK ferrule designs assure that all make and remake motion is transmitted axially to the tubing. Since no radial movement of the tubing occurs, the tubing is not stressed. The mechanical integrity of the tubing is maintained. No Distortion 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 nut. This assures that the nut will back-off freely for disassembly and permits a greater number of easy remakes. Sealing Positive, reliable connections with Parker CPI /A-LOK fittings have been qualified by exhaustive tests and over four decades of experience in the manufacture of quality tube fittings. Nomenclature Parker CPI /A-LOK fittings part numbers are constructed from symbols that identify the size and style of the fitting and material used. Assembly, Remake, Gaugeability Proper assembly is the key component to a leak-free system. CPI /A-LOK tube fitting assembly, remake and gaugeability instructions are found on page 74 of this catalog. Pressure Rating Tubing Selection For working pressures of CPI /A-LOK tube connections, please see the Instrument Tubing Selection Guide (4200- TS), found in the Technical Section of your Parker Instrumentation Products Process Binder, or the Parker Instrument Tube Fitting Installation Manual (Bulletin 4200-B4) at the end of this catalog. In some cases where a male or female pipe thread is the second end of a Parker CPI /A-LOK fitting, such threads may be the pressure limiting factor of the tubing system. Pressure ratings for Pipe Ends are shown on page 78. Huntsville, Alabama, USA Barnstaple, UK CPI /A-LOK Tube Fittings
