Shearwater Research REPLACEMENT Battery Cap - Radial Style

SWR-10503-01 01/23
Shearwater Research
$75.00

Qty:         

This is a Shearwater Research Radial Battery Compartment Cap for Shearwater Petrel 2 and NERD dive computers with blue O-ring. Effective Spring 2016, to improve the sealing performance and O-ring life span in Shearwater NERD and Petrel2 devices (including DiveCAN controllers), the battery compartment O-ring gland design has been changed from a crushed gland with black O-ring to a radial gland with blue coloured O-ring.

The new radial gland caps can NOT be installed on older computer cases, i.e. those manufactured prior to Spring 2016. Identification of the new radial cap can be made by observing the differences in the table image above. The cases which take the new cap will be engraved RC under the strap.

Description of New Radial Cap Sealing

  • Radial gland design
  • O-ring seals before computer turns on
  • Sealing NOT dependent on torque applied to battery cap
  • The compression on the O-ring is set by the gland groove diameter
  • Petrel computer marked with 'RC' under strap
  • NERD computer marked with 'RC' above battery compartment

Screw Type:
Machine Screw, Pan Head, #4-40 x 1/4-inch, Torx T10

Just to be clear, if you use the wrong cap, your dive computer will flood and it will not be covered by any warranty. Battery caps have no need for periodic replacement, you should only need a battery cap if you lose yours.
