The Scrubber Unit is designed to withstand extreme temperatures and harsh operating conditions, ensuring that you always have a clear view of the road ahead. This Scrubber Unit is the ideal choice for owners who demand reliability and performance.
The Washer Assembly is the central component of the Scrubber Unit, featuring a 5-liter reservoir made from high-density polyethylene with UV stabilizers. It includes an integrated electric pump that delivers fluid at a flow rate of 2.5 liters per minute. The reservoir has a large filler neck with a built-in strainer to prevent debris from entering the system. The assembly is designed to mount securely on the left side of the engine bay, with easy access for refilling and maintenance.
This specially shaped tube connects the washer pump to the nozzle feed lines. It is manufactured from flexible PVC with a steel wire reinforcement to prevent kinking. The formed tube is routed along the chassis to avoid heat sources and moving parts, ensuring consistent fluid delivery without restriction.
The End Cap is a protective cover that seals the end of the formed tube or a branch line. It is molded from EPDM rubber with a ribbed grip for easy installation and removal. The cap prevents dirt and moisture from entering unused ports, maintaining system cleanliness and preventing blockages.
This rubber grommet is designed to protect the washer tube as it passes through the vehicle body panels. It provides a watertight seal and prevents chafing of the tube against sharp metal edges. The grommet is made from weather-resistant EPDM and fits securely into a 25mm hole.
The Left Bracket is a steel mounting bracket that secures the washer reservoir to the inner fender on the left side of the engine bay. It is manufactured from 3mm thick steel with a zinc phosphate coating for corrosion resistance. The bracket features three bolt holes for secure attachment and a rubber pad to isolate vibration.
The Right Bracket is the symmetric counterpart used on the right side, but for this system, it is often used as an auxiliary support for the tube routing. It shares the same robust construction and finish, providing versatile mounting options.
These stainless steel clamps are used to secure the washer tubes and hoses to the brackets and vehicle frame. Each clamp features a worm-drive mechanism for precise tightening, ensuring a leak-proof connection without damaging the tubing. The band width is 12mm, and the clamps are available in sizes from 10mm to 25mm diameter.
This plastic tee connector is used to split the washer fluid line to feed both left and right windshield nozzles. It is manufactured from acetal resin with barbed ends that create a secure, leak-free seal when pushed into the hoses. The connector has a compact design that fits easily in tight spaces.
These high-strength round head bolts are used to secure the washer assembly and brackets to the vehicle structure. The bolts are M6 x 25mm with a class 8.8 rating, made from carbon steel with a zinc plating. The round head provides a low-profile finish, and the hex socket drive allows for easy installation with a standard Allen key.
These M6 flange nuts are used in conjunction with the round head bolts to provide a secure, vibration-resistant fastening. The integrated flange distributes the clamping load over a wider area, preventing damage to plastic components. The nuts are made from zinc-plated steel with a nylon locking patch for extra security.
There are two separate Washer Pipe Assemblies, each pre-cut to the exact length for routing from the tee connector to the left and right windshield nozzles. Each assembly includes a flexible nylon tube with an integrated check valve that prevents fluid from draining back into the reservoir, ensuring immediate spray when the pump is activated.
The Control Valve is a solenoid-actuated valve that regulates the flow of washer fluid to the nozzles. It is connected to the windshield wiper stalk and opens only when the washer function is activated. The valve is designed for fast response and minimal pressure drop, ensuring immediate and powerful fluid delivery to the windshield.
The Scrubber Unit features a high-performance pump that delivers a strong, consistent spray to the windshield, effectively removing dirt, bugs, and road grime. The pump is designed to provide immediate response with minimal delay, ensuring clear visibility whenever you need it.
All components of the Scrubber Unit are manufactured from high-quality materials that resist corrosion, UV degradation, and temperature extremes. The reservoir is made from UV-stabilized polyethylene, while the brackets and fasteners are zinc-plated steel, ensuring years of reliable service in harsh environments.
This Scrubber Unit kit includes every component needed for a full installation: reservoir, pump, formed tube, end cap, grommet, brackets, clamps, tee connector, bolts, nuts, pipe assemblies, and control valve. There is no need to source additional parts, saving time and ensuring compatibility.
The Scrubber Unit is specifically designed to fit the Sitrak C7H without any modifications. The brackets and tube lengths are pre-configured to match the vehicle’s mounting points and routing paths, ensuring a perfect fit and hassle-free installation.
