What is a wet kit on a semi truck?

A Wet kit, also known as a hydraulic kit, is a system that is installed on a semi truck to power additional hydraulic equipment such as a dump trailer, live bottom trailer, or a heavy-duty elevated platform trailer. A wet kit typically consists of a hydraulic pump, reservoir, control valve, and hoses. The pump is driven by the semi truck's engine and delivers pressurized hydraulic fluid to the control valve, which regulates the flow of fluid to the hydraulic equipment.

Wet kits can use either open center or closed-center hydraulic systems. An open center system allows fluid to flow continuously through the hydraulic system, while a closed-center system redirects fluid back to the reservoir when it is not in use.

There are several different types of wet kits available, including single-acting, double-acting, and power beyond kits. Single-acting kits operate in one direction, while double-acting kits can operate in both directions. Power beyond kits provide additional power beyond the hydraulic system, which is useful for powering other equipment such as snow plows or salt spreaders.

Wet kits are essential for many types of heavy-duty hauling operations, such as construction, mining, and oil and gas industries. They allow for greater flexibility and efficiency in transporting different types of cargo and equipment.
