X-Block Hydraulic Adapter

X-Block Hydraulic Adapter

Convert Your Single-Acting Pump into a Dual-Circuit Powerhouse

The X-Block Hydraulic Adapter is a patent-pending innovation that transforms your single-acting hydraulic pump into a dual-circuit system—perfect for powering both your dump hoist and an additional double-acting circuit like a jack or tilt deck. No need to replace your pump or power unit.

Compact, rugged, and tested under real-world conditions, the X-Block is engineered by Primary Mover to deliver professional-grade performance in dump trailers, truck conversions, and custom hydraulic builds.

Why You May Need a Manual Selector Valve

Most single-acting power units are designed to operate only one hydraulic function—usually your dump bed. To activate a second function (like a jack), you’ll need a way to divert flow. That’s where the manual selector valve comes in:

• Easily switch between your hoist and the secondary circuit

• Included in both Poly and Steel kits

• Required to control flow direction when using a single-function power unit

Optional Hose Kits for Double-Acting Jacks

If you're adding a jack to your system, we offer pre-cut hose pairs to complete your installation:

• 48" Hoses (Pair) – For compact installs

• 72" Hoses (Pair) – For mid-sized setups

• 120" Hoses (Pair) – For long frame runs or forward-mounted jacks

Add these at checkout for a plug-and-play solution.
