Morphology

sealless = seal (transparent) = seal + less

Built from the noun 'seal' (a sealing component) + '-less' meaning 'without', so the formation is directly interpretable.

Etymology

The word sealless comes from seal, meaning a part that stops leaks, and -less, meaning 'without', so a sealless pump or machine has no sealing part and is made to avoid leaks or contamination.
