To determine the correct length of spacer pins for your application follow the steps below:

1. Add up the cross sectional width of each ring of packing being removed.
2. Add the width of the lantern ring being removed (if one is used).
3. Add 1/8 inch for the inset of the gland follower ring.
4. Measure the depth of the stuffing box.
5. Subtract the sum of the removed packing rings and lantern ring and 1/8 inch gland follower recess from the stuffing box depth. The result is the length of the spacer pins required for this installation.

Spacing Pins are available in sizes taylored to fit most packing ring and lantern ring replacement sizes. Master Kits are available for WeeSeal Cages and Pins.
