Petro-Clear 40510D




PetroClear model 40510D 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 the PetroClear® model 40510D 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 filters.

PetroClear model 40510D “Dual Purpose” utilizes a standard 1" – 12 UNF mounting thread ref. (3/4" flow) required for most spin-on filter adapters used in Gilbarco, Wayne, Bennet, Tokheim and other major manufacturers’ dispensers, as well as with adapters used in the aftermarket.

Adapters are available for model 40510D in aluminum and cast iron. These single adapters are available in both 3/4" and 1" NPT and BSP inlet/outlet threads.
