This check valve kit fits our 12 Volt Differential Cooler Pump (Part No. 1239-002). If your pump takes forever to prime, the check valve may be leaking.
High-temperature Viton rubber construction is preferred when the pump is used for oil at temperatures from 160°F to to 300° F (70°C to 150° C). This is the same material supplied in our Part No. 1239-002 pump, but it can also be used to upgrade our Part No. 1239 pump from the original Buna N seals.
