c. Insert new seal:
ƒ For Teflon seal:
– Place the new Teflon seal onto the seal insertion tool with the seal opening facing away from the handle
– Lubricate the open-faced edge of the seal with Molykote 55 or other fine viscosity lubricant by placing a
dot of lubricant on your finger, then slowly rolling your finger around the outside lip of the seal, completely
coating the outside edge
– Insert the Teflon seal into the holder body by pushing the tool and seal straight into the body of the holder
Make sure the seal tool is straight with the holder to ensure you do not side load the seal
– Remove the seal tool
ƒ For graphoil seal:
– Insert the graphoil seal directly into the holder body Make sure you push the seal straight into the body of
the holder to avoid side loading the seal
4. Reassemble the holder
a. Apply a small amount of anti-seize lubricant to the lower body threads where the upper body threads on
Do not tighten the set screw until the upper and lower body of the holder are properly aligned . Tightening the set screw on
the threads will permanently damage the tool .
b. Loosen the set screw enough to allow for easy assembly
c. Thread the upper body of the holder onto the lower body
ƒ For Teflon seal:
– Tighten the upper body until it is snug against the lower body
– Tighten set screw
ƒ For graphoil seal:
– Do not tighten the set screw until after installation of the rod/shaft
– Thread, but do not tighten the upper body down to the lower body
 NOTE
When using a graphoil seal, tightening the upper body without a rod/shaft in the holder will damage the seal and prevent
insertion of the rod/shaft .
5. (Re)Install the rod/shaft
a. Clean the rod/shaft before installing
ƒ If reinstalling a used rod/shaft, thoroughly clean the rod/shaft with 320 grit or finer sandpaper using a
rotational motion, then wipe the rod/shaft with a clean rag and solvent to remove any leftover debris
ƒ If installing a new rod/shaft, wipe the new rod/shaft down with solvent and a clean rag to remove any debris
b. Add a small amount of Molykote 55 or other fine lubricant to the rod/shaft
c. Wrap the threaded end of the rod/shaft with two (2) complete wraps of Teflon tape to protect the seal during
rod/shaft insertion
d. Place the rod/shaft into the holder carefully If the rod/shaft cannot pass through the body, make sure the locking
collet is loose and oriented in the correct direction (dot on top) It is sometimes easier to completely remove the
locking collet from the body Be careful not to lose collet
 NOTE
Each insertion collet assembly is unique to each retrieval tool . Be sure to keep the removed assembly with the specific tool
retractor .
