STR36051 - Straub Open-Flex 1L Coupling

## Applications Suitable for repairing or joining pipes where access to the pipe end is difficult or not possible. The unique wrap-around design differs from similar type repair products because the installation or repair is permanent due to the unique flexible lip seal 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 Stc. C-219) or for permanent repairs or installation. ## Construction - Highest quality 316 Ti stainless steel construction - EPDM sealing sleeve - Casing: AISI 316 Ti - Screws: AISI 4135 steel - Bolts: AISI 12L 14 Galvanized ## Features - Accommodates up to 5° of pipe misalignment - Vary gap between pipe ends - Absorbs vibration, water hammer and sound - Special patented grip ring for superior holding power on hard-surfaced pipes - 5 year limited warranty - Reusable ## Installation 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. ## Safety Notes - Not pull-out resistant. - Ensure that pipes are properly anchored and supported. ## Specifications - Built to ASTM 1476, Type C, Class 2 specifications - American Bureau of Shipping (ABS) up to 232 PSI - National Sanitation Foundation ## Use - Joins like or dissimilar pipe materials: steel, galvanized, painted, stainless steel, thin-wall stainless steel, PVC, copper - Use with assembly tool: STR6648 ## Prop 65 Warning **WARNING**: This product contains lead, a chemical known to the State of California to cause cancer and birth defects or other reproductive harm.
