S42 Spray Gun Cup Lid
The 3M 26138 lid is a plastic replacement cover designed for S42 type spray gun cups used in pneumatic finishing applications. It fits professionals and DIY users who need a direct replacement to keep their existing cup assembly sealed and functional.
Build integration and clearance
This lid threads onto a compatible S42 cup to close the material reservoir during spray operations. It requires a matching S42 cup body and a standard spray gun setup, freeing the operator from improvising covers that can leak or contaminate the finish.
Bundled accessories impact
The product is supplied as a single lid with no additional components, adapters or lubricants included. Users must provide their own S42 cup and ensure threads are clean for a proper seal.

Questions about this item
Does the plastic lid withstand continuous solvent exposure during all-day spraying?
The S42-type plastic lid is designed for spray-gun cup use and resists common coating solvents during extended sessions.
How much heat builds up on the lid when the gun runs non-stop?
The plastic body stays near ambient temperature because it sits on the cup, not in the air stream, so heat rise is minimal.
Which 3M cup system must I already own for the 26138 lid to fit?
It fits 3M S42-series spray-gun cups, the matching cup platform for this lid design.
