RapidLOK™ features innovative high- and low-pressure and -temperature sealing couplings, connectors and product-recovery/pipeline-cleaning technologies for use in some of the most difficult and demanding liquid-handling applications. Offers a non-restrictive flow with no variation in pipe diameter when required and conditions allow. Reusable sealing components constructed of metals that have their own unique hardness and thermal properties for further reliability as temperature changes are encountered. Sleeve-retaining ring ensures safe venting at any residual pressure.
