Quick-Flex Elastomeric Couplings
Durability for the Long Haul

Quick-Flex elastomeric couplings are durable enough to perform in harsh environments, yet need minimal maintenance. This type of coupling is easy to install and requires no lubrication. The insert can be changed without removing the hubs. Thanks to the versatility of the design, elastomeric couplings are direct replacements for most comparable couplings.
