  1. Larger Diameter Hymax®14 – 24 Inches in Diameter Hymax is a Registered Trademark of Krausz Industries Ltd.

  2. Large Diameter Specifications Meets or exceeds AWWA C219 Center Ring – ASTM A53 Grade A Steel End Rings – ASTM A 795 Steel Gaskets – NSF61 EPDM for water and sewerage Nuts, Bolts, Washer, Bridge and other Misc. Hardware – Type 304 Stainless Steel Nuts, Bolts and Washers include an anti-gall dry lube coating Coating – 100% Fusion Bonded Epoxy for enhanced corrosion protection with average of 14 Mils thickness Min Pipe Insertion Depth – 2.25 inches Working Pressure 14-16 inch – 260 psi, 18-24 inch – 232 psi

  3. Large Diameter HymaxWide Range of Fit = Reduced InventoryLess Bolts = Fast Installation

  4. Installation Instructions for 14” through 24” Large Diameter Hymax Couplings

  5. Installation Instructions for 14” through 24” Large Diameter Hymax Couplings

  6. Precautions Please make the following notations when installing larger diameter Hymax Couplings • Always Verify Pipe Diameter with an O.D. Tape and Make sure it falls within the diameter range of the coupling • Always unpack the coupling and inspect for shipping damage • Prepare pipe ends and mark the stab depth according to directions • Back out Centering pins • Size Gasket According to Instructions • Never Lubricate Bolts (they are pre-lubricated) • Do lubricate ductile iron and asbestos pipe • Do not lubricate PVC, Steel or Polyethylene Pipe surfaces

  7. The Purpose of Centering Pins Pressure Build Up Here Can Create Coupling Movement Big End Small End Flow Direction Prevention of Coupling Drift Over Pipe End When in Maximum Transition

  8. The Purpose of Centering Pins Small End Flow Direction Big End If Coupling Moves Due to Pressure Differential, Centering Pin Bottoms Out on Pipe End Preventing Loss of Seal

  9. 14 to 24 Inch Hymax Installation ProcedurePrepare Pipe Ends – De-scale and Clean,Mark Pipe Ends for a Maximum Stab Depth of 5” 5” 5”

  10. Loosen Centering Pins(Anti Drift Pins) 1 - Pin in Set Position 2 – Pin Set for Installation Loosening of Pin allows for full Retraction of Coupling over pipe end

  11. 14 to 24 Inch HymaxStab Pipe Ends to the Proper Insertion Depth Remaining End Gap Between Pipe Ends is 2 – 3 Inches Pipe Ends Stabbed into Couplings

  12. After Stabbing Pipe, Tighten the Centering Pins to seat the “O”Ring Seal on the back side of the Pin Pins are One Inch Diameter – outside view

  13. Seated Anti-Drift Pin – Inside View

  14. Tighten All Bolts on Compression Ring to the required torque to properly seat the Gasket • Two Bolts per End • Torque Requirement is 150 ft. lbs. • Required Wrench – 17 to 21 inch long wrench handle and 15/16” (24 mm) pass through socket • Cross Tighten evenly • Always check for leaks prior to burial • If leakage occurs, re-torque nuts and bolts as required.
