The Halcyon Over Pressure Valve (OPV) with Gasket is a replacement part for any Halcyon wings.
Please note there are two different type of Halcyon OPV based on the manufacture date of your wing: the standard cord is made of thinner material while the coarse thread is slightly thicker (3mm).
Older Halcyon wings (pre 2019) require the standard OPV while newer wings (2019 to date) require coarse threaded OPV. The coarse thread is preferred by most divers, but especially when diving in cold water while wearing dry gloves or thicker neoprene gloves.
Features:
- OPV replacement part for any Halcyon wings.
- Standard cord is for older models (pre 2019).
- Coarse thread (thicker) is for newer models (2019 to date).
