4,200 PSI 4.2 GPM Cold Water Gas Pressure Washer with Honda GX390 Engine and CAT Triplex Pump on Stainless Steel Frame
The BE Power Equipment B4213HSJ is a commercial-grade cold water gas pressure washer delivering 4,200 PSI at 4.2 GPM, powered by a proven Honda GX390 389cc OHV engine and paired with a commercial-grade CAT 67DX39G1I P4 triplex pump with built-in unloader and fixed injector. Built on the 125S Stainless Steel Dealer Frame with 12" Ultra Premium flat-free tires and onboard accessory storage, the B4213HSJ is engineered for operators who need the long-term corrosion resistance of a stainless steel frame in demanding wet, outdoor, or chemical-exposure environments.
The 125S Stainless Steel Dealer Frame resists rust and corrosion more effectively than powder-coated steel over the long term, particularly in environments with regular water and chemical contact, coastal conditions, or high humidity. Whether you're cleaning concrete driveways, vinyl siding, agricultural equipment, trailers, or commercial building exteriors, the B4213HSJ gives you the power and durability to get the job done.
Built for Serious Outdoor Cleaning
The B4213HSJ is built to tackle demanding outdoor cleaning without slowing down. It is well suited for:
Cleaning residential and commercial exteriors including siding, decks, driveways, fences, and walkways
Vehicle, trailer, and equipment washing
Farm and agricultural equipment cleaning
Concrete and hard surface cleaning
Construction site cleanup and surface preparation
Features
Honda GX390 Engine
The B4213HSJ is powered by the Honda GX390 389cc OHV recoil start engine, a commercial-grade engine known for reliability, consistent output, and long service life. Key engine features include:
Reliable recoil start and smooth operation
High-torque OHV design for consistent output
Automatic low-oil shutdown to protect the engine from damage
Fuel-efficient OHV design for extended runtime
6.1 L / 1.6 GAL fuel tank for extended operation between refueling
The Honda GX390 engine is covered under Honda's separate engine warranty program.
Commercial-Grade CAT P4 Triplex Pump with Built-In Unloader
Paired with the Honda engine is a commercial-grade CAT 67DX39G1I P4 class triplex pump with built-in unloader. CAT Pumps is a trusted commercial and industrial pump brand known for reliability in high-pressure cleaning applications. The triplex design delivers smooth, consistent pressure output and longer service life compared to axial pump configurations.
The built-in unloader regulates water flow and maintains consistent pressure when the trigger gun is released, protecting the pump during bypass operation. The pump includes a thermal relief valve that releases built-up heat if the unit is left running with the trigger closed for an extended period.
The B4213HSJ uses a fixed injector — detergent is drawn at a fixed rate when the soap nozzle is attached. Switch to the soap nozzle to apply detergent, then swap back to a pressure nozzle to rinse. Operators requiring adjustable detergent concentration should consider the B4213HSJS, which features an external unloader and adjustable injector.
125S Stainless Steel Dealer Frame
The B4213HSJ is built on the 125S Stainless Steel Dealer Frame, a hand-truck style platform constructed from stainless steel rather than powder-coated carbon steel. Stainless steel provides superior long-term corrosion resistance in environments with regular water exposure, chemical contact, coastal salt air, or high humidity — extending the service life of the frame where standard steel frames would corrode over time. The frame includes onboard accessory storage for the hose, wand, and nozzles, with stabilizing rubber feet for steady operation.
50-Foot x 3/8" Single Wire Braided High-Pressure Hose
The included 50' x 3/8" QC single wire braided rubber hose provides durability and extended reach for cleaning large areas without repositioning the machine. The 3/8" diameter supports the full 4.2 GPM flow rate of this unit.
36" Insulated Spray Wand and Trigger Gun
The included 36" QC insulated spray wand provides reach and control for high, low, and hard-to-reach cleaning angles. The insulated design reduces heat transfer to the operator during prolonged use, and the quick-connect system makes nozzle changes fast and straightforward.
4 Quick-Connect Spray Nozzles
Four quick-connect nozzles cover a full range of cleaning applications:
