Which component allows air or gas to escape from a piping system?

Explanation:
Venting is the way to let air or gas escape from a piping system. When a line is filled or operated, trapped air can form pockets that block flow, distort pressure readings, or cause noise. A vent provides a controlled opening to the atmosphere specifically for releasing that air. Caps simply seal openings and stop escape; drains remove liquids or condensate rather than gas; and an orifice regulates flow, not venting. So a vent is the appropriate component to allow air to escape.
