Straub Flex 1L 48.3 – 168.3 mm

The Straub Flex coupling is designed to join just about any plain end pipe. The coupling has been designed with expansion and contraction movement in mind, as well as angular deflection. The coupling is designed as an alternative to metal and rubber expansion joints.
