Copied Straub Open-Flex 1L Coupling
Straub Open-Flex 1L Coupling
ApplicationsSuitable 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.UseJoins like or dissimilar pipe materials: steel, galvanized, painted, stainless steel, thin-wall stainless steel, PVC, copperUse with assembly tool: STR6648SpecificationsBuilt to ASTM 1476, Type C, Class 2 specificationsAmerican Bureau of Shipping (ABS) up to 232 PSIUnderwriter's LaboratoriesNational Sanitation FoundationFeaturesAccommodates up to 5° of pipe misalignmentVary gap between pipe endsAbsorbs vibration, water hammer and soundSpecial patented grip ring for superior holding power on hard-surfaced pipes5 year limited warrantyReusableConstructionHighest quality 316 Ti stainless steel constructionEPDM sealing sleeve standard, temperature range of -4Casing: AISI 316 TiScrews: AISI 4135 steelBolts: AISI 12L 14 GalvanizedInstallationRequires 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 notesNot pull-out resistant.Ensure that pipes are properly anchored and supported.
