When performing a smoke test, you need to seal all openings except the one where smoke is introduced and the suspected leak area. These caps come in various sizes to fit different hose connections, ports, and openings commonly found in EVAP systems, intake manifolds, and other sealed systems.

How to Use:

1. Identify all openings in the system being tested
2. Select appropriate size cap for each opening
