DIN O-RING 1st stage

Scubapro DIN O-Ring for First Stage Regulators

This Scubapro O-Ring is a replacement O-ring for the DIN fitting on the first stage of the regulator, meaning it is the O-ring you find at the connection of your first stage on the regulator. Unfortunately, this O-ring tends to get lost or damaged, so you should always have a suitable replacement DIN O-ring with you on diving trips and excursions, as without this O-ring, you cannot attach your DIN regulator to a scuba cylinder.

This O-ring is compatible with all Scubapro DIN regulators and is also sized to fit all similar regulators from other manufacturers.
