How to determine the correct Gland Packing size
• Measure diameter of shaft.
• Measure inside diameter of gland (or stuffing box).
• Gland ID - Shaft Diameter divide by 2
This figure gives you the cross section of the area to be packed.
• From the table, choose the gland packing with the closest size.
If your figure is in-between, use the next size up.
