OceanPro replacement HP air spool
The OceanPro HP Air Spool is the small sealed connector between a compatible high-pressure hose and pressure-gauge swivel. Its two O-rings seal the connection while allowing the gauge fitting to rotate as designed.
Use the listed OceanPro reference S10516 when asking DGA to identify the appropriate replacement for your gauge assembly.
A worn or damaged spool seal can be one possible source of a leak at the gauge connection. Have a qualified technician identify the fault and match the spool dimensions and seal requirements to the exact instrument; a similar appearance does not establish interchangeability.
This is a useful workshop spare, or a trip-support spare when a qualified technician is available. Store it clean in a labelled parts container so the small spool and seals are not lost or contaminated. Installation and pressure testing should follow the instrument manufacturer’s service requirements before the gauge returns to use.
