Halcyon - OVER PRESSURE VALVE (OPV) WITH GASKET

Halcyon replace OPV for all Halcyon wings.

Please make sure to select the correct Halycon OPV based on the date of manufacture of your wing. The standard cord is a thinner material and is what comes stock on all Halcyon wings.

Older Halcyon wings (pre 2019) require the fine threaded OPV, while newer (2019 to date) require coarse threaded OPV.

The 3MM cord is a little thicker and is sometimes preferred by divers using dry gloves or thicker gloves.
