3M 26104 S20 Spray Gun Cup Lid

The 3M 26104 is a replacement cup lid designed for S20 type spray guns used in automotive refinishing and industrial coating. It suits technicians who need a direct-fit plastic cover to keep paint containers sealed during application or storage. This component supports consistent spray patterns by preventing debris from entering the cup. It is not for users requiring metal lids or adapters for non-S20 gun models.

Installation and common issues

The plastic lid threads onto compatible S20 cups by hand without tools, making swap-outs quick between colour changes. Over-tightening can strip the fine threads or crack the moulded flange, leading to leaks under pressure. Cross-threading is the most frequent error; always start the lid squarely and turn gently until the gasket seats. Damaged sealing surfaces on the cup itself will also cause fluid seepage regardless of lid condition.

Questions about this item

How can I confirm the 26104 S20 lid seals correctly after fitting it to my spray gun cup?

Fill the cup with material, attach the lid securely and operate the gun; a consistent spray pattern with no leakage around the rim shows the seal is working.

What comes in the box and do I need to buy a cup or gasket separately for the 26104 S20 lid?

The package contains only the plastic S20-type lid; the matching spray gun cup and any required gasket are sold separately.
