Replacement O-Rings for Shearwater

Replacement O-Ring Options
Replacement O-Ring Options
  • O-Ring replacements for Shearwater devices
  • Perdix/Petrel battery compartment cap O-Rings are sold in a set of two
  • Swift transmitter body O-Rings are sold in a set of two
  • Legacy transmitter battery door O-Ring and HP fitting O-Ring are sold each

These are commonly requested O-Rings for the Shearwater Research branded dive computers and transmitters. The O-Rings are sizes, durometers, and materials that are widely available in generic versions, but the OEM O-Rings are supplied to us directly from the Shearwater factory. The O-Ring color may vary and is not significant to the application.

  • Perdix AND Petrel Dive Computer - The Perdix battery compartment cap requires two of this O-ring and the Petrel battery compartment cap requires one O-Ring. These OEM O-Rings are AS568-112 size, Shore A 70 durometer, Nitrile. Sold as a set of two. (This O-Ring size is identical to that commonly used in the nose of many DIN regulator fittings.)
  • Legacy Transmitter Battery Door - The PPS transmitter (what Shearwater now calls the "legacy" transmitter) battery is under a battery compartment cap on the end of the transmitter. Shearwater specifies the legacy transmitter battery compartment cap O-Ring as AS568-016 size, Shore A 70 durometer, Nitrile. The Legacy transmitter battery compartment cap requires one O-Ring; sold each. (This O-Ring size is not commonly seen in SCUBA applications.)
  • Swift Transmitter Body - The Swift transmitter battery is under the body housing, which must be removed to access the battery. Shearwater specifies a Metric size for this OEM O-Ring as 24 X 1.5mm, Shore A 70 durometer, Nitrile. The Swift transmitter body requires two O-Rings; sold as a set of two. (This O-Ring size is not commonly seen in SCUBA applications.)
  • Transmitter High Pressure Fitting - Both the Legacy and Swift transmitter high pressure fitting that screws into the first stage HP port requires a standard first stage HP port O-Ring. Shearwater specifies the ISO version size of this OEM O-Ring as AS568-904, Shore A 75 durometer, oxygen compatible Viton. The transmitter high-pressure fitting requires one O-Ring; sold each. (The commonly available Imperial size is virtually identical to the ISO version and Shearwater has confirmed to us that a standard AS568-012, Shore A 90 durometer, Viton will work equally well in this application. )

Shearwater tells us that none of these O-Rings require routine periodic replacement under normal circumstances, with exception of the HP port O-Ring if the transmitter is frequently removed from the regulator first stage. FYI, both the Legacy and Swift model transmitters use a widely available standard CR2 size 3.0v lithium battery.
