  1. Watertight Gasket Installation Guide Presented By:

  2. INSTALLINGRUBBER GASKETS FOR WATERTIGHT JOINTS SINGLE OFFSET O-RING PROFILES

  3. THINK SAFETY 1st • Practice ALL safety precautions. • Follow all OSHA & Manufacturers’ safety recommendations. • Wear protective gear

  4. O-Ring Circular Profile Single Off-Set Triangular Profile Gasket Types

  5. O-Ring Circular Profile Single Off-Set Triangular Profile Gasket Types Assembly method of these 2 gaskets is NOT the same

  6. Lube gasket and lube spigot BEFORE installing gasket onto spigot ONLY Assembly Difference O-RING Lube spigot AFTERputting on the gasket SINGLE OFFSET

  7. Step One Clean & Inspect Joints

  8. Step 1 – Clean & Inspect Clean the bell AND spigot Remove all dirt and debris

  9. Step 1 – Clean & Inspect Inspect the Bell and Spigot

  10. Step 1 – Clean & Inspect Look for cracks & chips.

  11. Step 1 – Clean & Inspect REPORT findings to supervisor for disposition. Good

  12. Step Two Install Gasket-Equalize

  13. Step 2 – Placing the Gasket LIFT the precast following proper handling & safety procedures Lift Bar Lift Pins

  14. Step 2 – Placing the Gasket LIFT the precast following proper handling & safety procedures

  15. Step 2 – Placing the Gasket Step 2 – Placing the Gasket Place Ridges AGAINST Spigot Ridges Spigot

  16. Step 2 – Placing the Gasket Make sure the gasket is fully seated in the shoulder or groove of the joint SHOULDER GAP

  17. Step 2 – Placing the Gasket Push gasket against shoulder or groove Remove Gap. SHOULDER

  18. Step 2 – Placing the Gasket It is important to equalize the gasket to remove bunching and overstretching

  19. Step 2 – Placing the Gasket Insert screwdriver or other blunt, rounded instrument

  20. Step 2 – Placing the GasketEqualize gasket to remove bunching and overstretching Go completely around the structure to insure the gasket is stretched evenly around the joint.

  21. Step 2 – Placing the Gasket Visually recheck the gasket to make sure it is seated snugly against the groove

  22. Step Three Lubricate

  23. Step 3 – LubricationProper Lube Use clean lube

  24. Step 3 – LubricationGenerously Lube the Bell LUBE INSIDE THE BELL

  25. Step 3 – LubricationGenerously Lube For SINGLE OFFSET, place lube on top of gasket AFTER ASSEMBLY onto spigot For O-RING, lube spigot and lube gasket, THEN ASSEMBLE onto spigot.

  26. Step 3 – LubricationGenerously Lube the Gasket REMEMBER! For Single Off-Set Gaskets…. Lube goes ON TOP of Gasket Do NOT Place Lube on a Bare Spigot

  27. Step Four Set Sections

  28. Step 4 – Set the Precast Section KEEP THE STRUCTURE LEVEL AND PLUMB

  29. Step 4 – Set the Precast Section KEEP THE STRUCTURE LEVEL AND PLUMB

  30. Step 4 – Set the Precast Section COMPLETE THE SECTIONS

  31. Step Five Visually Check

  32. Step 5 – Visual Inspections Walk around the structure to verify the section is seated evenly

  33. Step 5 – Visual InspectionsLook inside and outside structure Make sure the joints are seated evenly all around

  34. SUMMARY • SAFETY 1st • CLEAN, INSPECT JOINTS • PLACE GASKET - EQUALIZE • LUBRICATE • SET PRECAST – ENSURE LEVEL • RE-INSPECT Gasket Installation

  35. REMEMBER Lube gasket and lube spigot BEFORE installing gasket onto spigot O-RING Lube spigot AFTERinstalling gasket SINGLE OFFSET
