Parker CPI™/A-LOK® Instrumentation Tube Fittings are designed as leak-free connections for process, power and instrumentation applications. The CPI tube fittings utilize a single ferrule for easy make-up and excellent performance in vibration applications. The “spring loaded” effect of the single ferrule creates a constant tension between the fitting body and fitting nut. The A-LOK two ferrule compression tube fittings are designed to provide reliable leak-free connections for applications that specify a two ferrule system. These single and two ferrule fitting designs are manufactured to the highest quality standards and are available in a broad range of sizes, materials and configurations.

NOTE:

Dimensions for reference only, subject to change.

A and C dimensions are typical finger-tight.

Tube stub is pre-grooved as standard. Generic (non-grooved) can be ordered through Quick Response Department.

Size 1, 2, and 3 do not require a groove.

Add -Z6 for assembly of nuts and ferrules on the tube stub end.
