Seal Rite 550-Gallon Hand Agitated Seal Coat Trailer

The Seal Rite 550-Gallon Hand Agitated Seal Coat Trailer is a heavy-duty, contractor-grade sealcoat transport and agitation solution designed for crews that require higher material capacity without the complexity of a powered spray system. This unit is NOT a spray system. It is engineered for professional contractors who apply sealcoat using squeegees, brushes, or pour methods and need consistent material mixing, safe transport, and long-term durability on larger jobs.

Built around a rugged 550-gallon steel tank, this trailer is ideal for residential subdivisions, medium to large commercial parking lots, and maintenance projects where increased volume, dependable agitation, and mechanical simplicity are critical. The hand-agitated design eliminates hydraulic or engine-driven components, reducing maintenance demands while still delivering thorough, uniform material mixing throughout the workday.

Heavy-Duty Steel Tank Construction

The tank is constructed with a 7-gauge steel head and 10-gauge steel sidewalls, providing excellent resistance to abrasion, material weight, and long-term wear. This heavy steel construction supports higher material volume without flexing or deformation during transport or agitation.

A properly built tank is the foundation of any sealcoat system. By using heavy-gauge steel throughout the tank, this unit is designed to handle demanding contractor use while delivering dependable performance season after season.

Full Sweep Hand Agitation System

The full sweep 4-paddle hand agitation system is engineered to keep sealcoat material evenly mixed throughout the entire 550-gallon tank. The 3:1 gear reduction allows operators to agitate heavier material loads efficiently with reduced physical effort.

Each paddle is equipped with rubber wiper blades that scrape the tank walls clean during agitation. This minimizes material buildup, reduces wasted product, and supports consistent blending—especially important when working with sanded sealcoat mixes.

Hand agitation provides reliable mixing without hydraulics, engines, or fuel systems, making this trailer an excellent choice for contractors seeking durability, simplicity, and lower long-term operating costs.

Contractor-Grade Trailer Package

The trailer is built for stability, safety, and road compliance. It features a 2 5/16” Bulldog hitch rated at 12,500 lbs, adjustable safety chains, and a breakaway switch for secure towing under load.

A 6,000 lb E-Z Lube axle with electric brakes supports the increased tank capacity while simplifying routine maintenance. The lighting system includes brake lights, running lights, a center light bar, and a lighted license plate bracket to ensure visibility during transport between job sites.

Large Manway and Material Handling Features

Material loading and tank access are handled through a 25” gasketed manway, providing ample space for adding sealcoat, sand, and additives. The manway includes a sand grate and bag splitter, allowing crews to load material efficiently while reducing clogging and contamination.

An inner splash lid helps control material movement during agitation, while the lockable outer lid adds security during transport and storage.

Material discharge is managed through a lockable 2” full-port ball valve, paired with an aluminum quick coupler for fast, clean, and reliable hose connections.

Designed for Higher-Volume, Hands-On Sealcoating

The 550-gallon capacity makes this trailer well-suited for contractors handling larger daily production volumes without stepping into powered spray systems. Fewer powered components mean reduced downtime, simpler maintenance, and dependable performance during peak season.

This trailer is ideal for crews who want higher capacity while maintaining hands-on control over material application.

Is this suitable for commercial work?
Yes. The 550-gallon capacity is ideal for residential subdivisions, commercial parking lots, and maintenance projects.

Does the trailer include brakes?
Yes. It features a 6,000 lb axle with electric brakes and a full DOT lighting package.

Use Case Example

A contractor servicing large residential developments uses the 550-gallon hand agitated trailer to increase daily production without adding engine or hydraulic maintenance. The higher capacity reduces reload frequency, while the hand agitation system ensures consistent material mixing across multiple driveways and small commercial lots.

Differentiation

Compared to smaller hand-agitated units, the 550-gallon model delivers increased capacity while maintaining the same mechanical simplicity. It offers professional-grade durability and higher productivity without the added cost and complexity of powered spray systems—making it an ideal step-up solution for growing sealcoating operations.

Note: The 550 Trailers are dual axle trailers.
