Dixon Straub Open-Flex 1L Couplings

Vendor: Dixon Pipe and Welding Fittings

Coupling Type: Valves, Flow Control, & Strainers

Description:

For permanent Repair

Coupling Category:

Valves

Straub Open-Flex 1L couplings are suitable for repairing or joining pipes where access to the pipe end is difficult or not possible. This unique wrap-around design differs from similar type repair products because the installation or repair is permanent due to the unique flexible lipseal gasket design. Open-Flex couplings will also act as an expansion joint. Straub Open-Flex couplings do require the pipes to be properly anchored and restrained as they are not pull-out resistant like the Straub Grip-L couplings. Use Straub Open-Flex couplings to replace bolted sleeve type couplings (AWWA Std. C-219) or for permanent repairs or installation.

Joins like or dissimilar pipe materials: steel, galvanized, painted, stainless steel, thin-wall stainless steel, PVC, copper Requires no special tools or pipe-end preparation; only a torque wrench is required for a secure and safe pipe connection that seldom needs retightening. highest quality 316 Ti stainless steel construction accommodates up to 5° of pipe misalignment vary gap between pipe ends absorbs vibration, water hammer, and sound acts an an expansion joint; will accept up to .25" of axial movement 5 year limited warranty reusable conforms to ASTM 1476, Type 2, Class 3 specifications
