Frequently Asked Questions
Check your sprayer or gun’s parts diagram/BOM. If the diagram lists 104938 at the swivel-to-handle joint or inlet/suction joint, it’s the correct seal for your unit.
Yes—if the leak originates at the swivel-to-handle interface on a model that specifies 104938, replacing the worn packing typically restores a proper seal and stops drips/air ingress.
Some suppliers cross-reference 104938 to “#113” for certain LineLazer style units. Always verify against your lineup’s official parts list before ordering.
Typically no. A clean seat and light lubrication are sufficient. Follow the procedure in your gun/sprayer manual; avoid adding sealants that may degrade the O-ring.
