A breathing bolt is a vented fastener that allows a sealed housing, gearbox, or fluid reservoir to equalize internal pressure with the surrounding atmosphere during heating and cooling cycles. Without a properly functioning breathing bolt, pressure differentials can build inside the housing, forcing fluid past seals and leading to leaks or premature seal failure. Replacing a damaged or clogged breathing bolt restores correct pressure balance and protects the integrity of the components it serves.
