Parker's economical compress-align fittings are pre-assembled with a captive sleeve which is always Oriented Correctly for faster assembly. The captive sleeve gives a visible inspection before and after installation and the design of the sleeve aligns to seal even out-of-round tubing. Compress-align can be used in many areas where flare fittings are used due to the higher pressure rating, meaning no flaring, soldering or tube preparation resulting in faster installation. Compress-align bodies are interchangeable with standard compression bodies so inventory is decreased.
