This device may replace an external bypass valve, but it is not intended to bypass the total oil flow.

BSPP threads are 55° full form whitworth. Selection Procedure Performance Curves Performance Curves are based on a 40°F approach temperature, a 2:1 oil to water ratio and an average oil viscosity of 100 SSU. Example: oil leaving cooler at 125°F with 85°F cooling water (125°F - 85°F = 40°F). The 2:1 oil to water ratio means that for every GPM of oil circulated, a minimum of 1/2 GPM of water must must be circulated to obtain...
