Conexões CPI / A-LOK Parker

The Parker CPI / A-LOK tube fitting has been specifically designed for use on instrumentation, process and control systems, analysers and environmental equipment employed ind  chemical, pretroleum, power generationg anda pulp and paper plants. CPI – A-LOK fittings have also been used extensively in other aplplications and insutries wherever high reliability and quality are required.

A 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 avaiable in a broad range of sizes, materials and configurations.


Parker CPI / A-LOK fittings are available as standard in Heat Code Traceable, 316 stainless steel.

Other 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.

For nuclear and other critical applications, stainless steel CPI / A-LOK fittings are readily avaiable with documented heat code traceability.


Parker CPI / A-LOK tube fittimgs are available in combination with a variety of ISO and ANSI pipe thread configurations. For a full listing of these fittings.


Parker CPI / A-LOK tube fittings can be used with a wide variety of tubing materials and a broad range of tube wall ticknesses. CPI / A-LOK seals equally well on both thin wall and heavy wall tubing.


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 integrily of the tubing is maintained.


In make-up, there is no undue force in an putward direction to distort the fitting body or ferrules to cause interference between the ferrules and nut. This assures that the nut
