Lisle HD Thermostat Seal Installer

Used On Most CAT, Cummins and Detroit Diesel Engines (Class 7 and 8 Trucks).

The double-sided centering bushing guides the seal driver so that seals can be easily installed straight into the recessed port in the thermostat housing. For seals without a stop flange, the handle provides the stop to install the seal to the correct depth in the housing.
