Regulator Service Intervals and Bench Specs, by Model
The service interval and the bench settings our technicians work to for every regulator model we certify, straight from the manufacturers’ service documentation. Use it to check a used regulator, or to see when yours is due.
Intermediate pressure is measured with the first stage pressurized and no flow; it must reach the range and hold there without creeping. Cracking effort is the inhalation pressure at which the second stage begins to flow, measured in inches of water. Where a manufacturer publishes a dive count as well as a calendar interval, whichever comes first applies.
Every certified used regulator on DescendAgain is tuned to these numbers and the measurements are recorded against its serial number. Click a model for its page: what is in stock, what has sold, and the full spec.
