TOOLCY Pressure Washer Pump Max 4000 PSI • 4.2 GPM Triplex, 1" Shaft, Direct Drive

Renew Your Gas Pressure Washer with TOOLCY

Upgrade or refresh your gas-powered washer with the TOOLCY Max 4000 PSI, 4.2 GPM triplex pump. Designed for horizontal engines, this replacement unit delivers robust pressure and dependable water flow, ideal for residential tasks such as driveways, decks, fences, sidewalks, and vehicles. The system emphasizes reliability, durability, and ease of maintenance, without making promises you can’t measure in real-world use.

The pump body features a fully anodized black crankcase and a solid brass pump head, chosen for strength and long-term performance. The triplex arrangement is engineered to run smoothly under load, with a built-in sight glass and advanced oil seal technology that helps you monitor lubrication at a glance. This combination aims to reduce downtime and extend service life in daily cleaning sessions.

Adjustable Control for Versatile Cleaning

An adjustable unloader lets you tailor pressure output to match your engine and the job at hand. When you need quieter operation or idle ease, you can reduce pressure, helping you balance cleansing power with noise and load tolerance. This control is designed to support a wide range of installations and user needs.

The pump is built to fit common industry mounting patterns and comes with a 1-inch shaft hole for compatibility. Standard SAE mounting spacing (diagonal 6 1/2 inches; short-side 3 1/4 inches; long-side 4 1/2 inches) helps simplify installation on many engines. For seamless connections, it includes a 3/4 inch garden hose inlet and a 3/8 inch quick-connect outlet, making setup straightforward for a variety of setups.

Maintenance, Performance, and Included Accessories

The oil pre-fill and sight glass system lets you verify oil levels quickly—an easy reminder that maintenance matters. While the unit is designed for cold-water operation, you can keep a regular schedule of oil checks and periodic changes (around every 60 running hours) to maintain steady performance.

• Complete accessories package with five nozzles supports multiple cleaning patterns for different jobs
• Chemical injection capability enables detergent delivery where appropriate
• Ready-to-install kit with essential components for immediate operation and compatibility with a broad range of engines

In real-world use, this TOOLCY pump can refresh an aging washer, help you tackle concrete, wood, and vehicle detailing, and fit neatly into compact, space-conscious setups. You gain a robust, adjustable, plug-and-play solution that prioritizes reliability and practical performance over hype.
