We just acquired a small amount of Vintage New Old Stock hp seats. These were stored in a shop parts bin for decades, so they have varying degrees of discoloration that does not affect the performance.

This is a an OEM new old stock US Divers/Voit part. This seat fits all US Divers and Voit non balanced first stages found in double hose regulators. This includes Trademark, Broxton, DA Aqua-Master, Voit Lung, Voit Navy.

*Note the DA Aqua Master did NOT experience a change in nozzle, or inner parts so the same HP seat is used for both the rectangle label and the Large Circle decal . Please do not confuse this label change with the "Royal"

*Regulator service parts are only to be installed by a trained regulator technician. Using these parts incorrectly can cause serious injury or death.
