Petro-Clear 40510D-AD




PetroClear model 40510D-AD is a particulate removing, phase separation and water sensing spin-on filter. This filter is designed to sense water, both free and emulsified, and slow flow as an indicator of the presence of water in neat gasoline. This filter is also designed to detect and react to phase separation. Slow flow is an indicator of the presence of phase separation in Ethanol blended gasoline.

Once PetroClear® model 40510D-AD has absorbed 5.9 ounces (175 mil) of water from neat gasoline, flow will be noticeably slow.

The chemical center core assembly detects and reacts to phase separation and significantly restricts flow through the filter.

PetroClear model 40510D-AD “Dual Purpose” high-flow filters utilize a standard 1.5" – 16 UNF mounting thread ref. (1" flow) required for most spin-on filter adapters used in aftermarket and/or today’s high-flow fuel applications such as in Gilbarco, Wayne, Bennet, Tokheim and other major manufacturers’ dispensers.

Adapters are available for model 40510D-AD in aluminum. Inlet/outlet sizes are available in 3/4" and 1" NPT or BSP inlet/outlet threads.
