The Company With Connections TMTHE NEXT LEVEL OF FLEXIBLE CONNECTORS A-LOK PREMIUM ASTM C-923 APPLICATIONA LOK PREMIUM Designed to produce aguaranteed watertightseal between pipe andconcrete, the A LOK Premium flexible pipeto-manhole connectorprovides maximumperformance on the jobsite. Its unique designnot only saves valuableproject time, but alsoensures longevity andoffers unsurpassedenvironmental benefits.KEY ADVANTAGES (Continued)Precast ConcreteManholeSmooth WallPipeClose-up ViewShowingConnectorsFlexibilityA LOK Premium Cast in A-LOK Premium Connector.For all types of smooth wall pipe.connectors preventinfiltration andex-filtration into wastewater or stormwater systems, and are installedin the precast structure in a way that does not require coring orplacement after the base component is cast. This eliminates residualwaste from coring, disposal of the slugs or wasted raw materialutilization or energy. Once cast-in, the connector becomes an integralcomponent of the structure wall.A LOK Premium has demonstrated in tests that it will meet andexceed 13 psi of hydrostatic water pressure.MATERIALExtruded from compounds formulated for wastewater applicationsand engineered to conform to the requirements ofsection 4.1.1 of ASTM C-923, the standard rubber connector isavailable in alternative compounds upon request. Contact an A LOK representative regarding special applications, such as the presence ofhydrocarbons.KEY ADVANTAGESThe external appearance of the A LOK Premium connector appears tobe a standard connector, but under differential loading or pipe deflectionit will instantaneously react and redistribute its visco-elastic dynamiccore material to maintain its circumferential sealing pressure. Thisvisco-elasticity behavior is made possible by introducing a blend ofenvironmentally friendly fibers, binders, polymers and congealing agentsinto the connector core which provides a controllable and dynamicviscose fluid within the connector. In most installations, this material willremain equally distributed throughout the core of the connector providedproper pipe bedding practices have taken place. In the event that shortterm or long-term settlement of the pipe begins to occur, the corematerial will react by redistributing and equalizing the blended materialsto maintain its proper sealing compression.A specific combination of fibers and congealing agents have beenselected to prevent the escape or loss of material through absorption orfrom minor punctures or tears that could occur during the initial couplingof the connector and during its service life.Benefits and advantages include:1. Functioning on pure compression, the A LOK Premium allowsfor fast and easy field installation. After the pipe is beveled andthe connector and pipe are cleaned and lubricated, the pipe issimply centered in the connector and inserted. Backfilling canbe done immediately, thus enhancing project safety andovercoming the typical problems of water, running sand andother unstable trench conditions.2. Efficient geometry of the profile lowers the coupling force required toinsert the pipe into both radius and flat wall connector designs.Lower coupling force translates into quicker and easier installation.3. Increased nominal pipe diameter tolerance over conventionalcompression connector designs while still maintaining up to 10degrees of omnidirectional axial deflection.4. Dynamic self-sealing core material can compensate for changes indimensions and physical eccentricity.5. Available in a range of sizes from 12” through 90” utilizing existingA LOK mandrels.6. Backed by our standard A LOK Watertight Guarantee.7. Like other A LOK connectors on larger-diameter pipe where sizeprohibits a gasket from being installed in a flat plane, the A LOK Premium can be configured for casting in a curve with the connectorstaying perpendicular to the center line of the pipe. Discoveredthrough years of extensive research and development, thisconfiguration causes no loss of compression or deflection.PRODUCT REFERENCESA.)
