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

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

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

7. ONLY Assembly Difference Lube gasket and lube spigot BEFORE installing gasket onto spigot Lube spigot AFTER putting on the gasket O-RING SINGLE OFFSET

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

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

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

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

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

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

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

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

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

19. It is important to equalize the gasket to remove bunching and overstretching

20. Insert screwdriver or other blunt, rounded instrument

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

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

24. Step 3 – Lubrication Proper Lube Use clean lube

25. Step 3 – Lubrication Generously Lube the Bell LUBE INSIDE THE BELL

26. Step 3 – Lubrication Generously 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.

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

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

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

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

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

34. Make sure the joints are seated evenly all around Step 5 – Visual Inspections Look inside and outside structure

35. SAFETY 1st CLEAN, INSPECT JOINTS PLACE GASKET - EQUALIZE LUBRICATE SET PRECAST – ENSURE LEVEL RE-INSPECT

36. O-RING SINGLE OFFSET REMEMBER Lube gasket and lube spigot BEFORE installing gasket onto spigot Lube spigot AFTER installing gasket
