A first stage that starts creeping can turn a small seat problem into a blown hose or a ruined dive. This compact Dive Rite Overpressure Valve threads into a spare low pressure port and simply vents gas if the intermediate pressure climbs past its limit, protecting your hoses and giving you an early warning that something needs attention. It is a particularly smart addition on stage, deco and sidemount regulators that may not have a second stage attached to act as a relief. Installation takes a minute and no special tools.
