Description

The 33953 Seal Kit, often referred to as the “Hot Kit,” is a specialized high-temperature repair set for Cat Pumps. While standard seal kits are rated for temperatures up to $140^{\circ}\text{F}$, this kit is specifically engineered for applications where the inlet water temperature reaches up to $190^{\circ}\text{F}$.

It is primarily used in the 4SPX series plunger pumps (like the 4SPX32G1I) when they are integrated into hot water pressure washers or industrial systems that utilize pre-heated water.
