PowrLiner 4955

High-Quality Replacement Parts for Your Sprayer

The PowrLiner 4955 is a heavy-duty, professional-grade line-striping machine built for contractors who need to complete medium to large-scale striping projects efficiently and profitably. With its powerful hydraulic delivery system, durable construction, and thoughtful ergonomic design, the 4955 is engineered to deliver consistent, high-quality pavement markings on parking lots, athletic fields, roadways, and other large surfaces. It is especially suited for contractors who perform frequent striping jobs and require reliable, long-term performance. 

The 4955 model supports one or two-gun configurations, and is compatible with both gas-powered and electric drive (with optional convertor kit), giving you flexibility depending on job-site requirements. It also offers ergonomic handling and easy maneuverability features that improve productivity and reduce operator fatigue. 

Whether you’re painting parking-lot lines, lane markings, airport runways, or athletic field boundaries, the PowrLiner 4955 delivers professional striping results with consistency and durability. 

Key Features

• PowrCenter™ Dashboard Control: Centralized and user-friendly control panel including pressure gauge, storage tray, tip holder, and even a cup holder, making operation more convenient and organized. 
• SmartArm™ Gun Mount & Versatile Gun Bracket: The spray gun mount can pivot and lift for quick adjustments, and the gun bracket can be positioned for spraying on the left, right, front, or rear, maximizing flexibility for different striping patterns.
• Precision Pressure Control: Adjustable pressure range from approximately 400 to 3300 PSI, enabling you to spray light-bodied coatings as well as heavier, low-VOC striping paints suitable for a wide variety of marking materials.
• Durable, Heavy-Duty Frame: Epoxy-finished frame resists harsh solvents, corrosion, and tough jobsite conditions, ensuring long-term durability even under heavy, repeated use.
• Dual-Gun Capability & Comprehensive Kit: The 4955 typically ships with two S-3 stainless steel spray guns and a premium line-striping tip (e.g., TR1), plus hoses and tip kits enabling wider or dual lines, improving productivity on larger jobs. 
• Flexible Power Source( Gas or Electric): Standard gas-powered (e.g., with a Honda engine) but easily convertible to a 2-HP electric DC motor with an optional kit useful for sites where gas engines are not allowed or where quieter operation is preferred. 
• Pneumatic Tires & Hose Storage: Large pneumatic wheels for easy maneuvering (even on rough surfaces) and a rear hose rack for convenient storage and clean setup.
  
  

Applications

The PowrLiner 4955 is ideal for:

• Parking lots and commercial zones — striping parking spaces, directional arrows, handicap markers, and safety lines.
• Roadways, streets, and road marking projects — lane markings, edge lines, crosswalks, and other traffic-guidance markings.
• Athletic fields, stadiums, and sports grounds — marking boundaries, lanes, and field lines with precision.
• Airports, industrial complexes, and large paved surfaces — runway markings, loading-zone demarcations, safety markings.
• Municipal, commercial, and contractor striping services — frequent, large-scale striping jobs requiring reliable performance and fast turnaround.
  
  

FAQ’s

Q1. What parts are covered under the Main Assembly / Cart Assembly / Hydraulic System?

These include the main frame, cart/handle assemblies, hydraulic pump and motor, drive belt guard, caster and support assemblies, essentially the core structural and drive components of the machine.

Q2. What does the “Fluid Section” refer to?

The Fluid Section includes the paint hopper or reservoir, suction and return systems, filters, fluid hoses, high-pressure hoses, valves, and seals, all components involved in storing, transferring, and pressurizing the striping paint or coating.

Q3. When should I consider replacing the “High Pressure Filter” or “Bleed Hose Assembly”?

If spray quality deteriorates, high-pressure filter fluctuates, or the pump seems to strain, it may signal a clogged filter or a worn bleed hose/valve. Replacing these parts helps restore consistent flow and maintain line quality.

Q4. Can I convert my 4955 from gas to electric, and what sub-category covers the conversion parts?

Yes, the “DC Electric Convertokit (120V)”  provides the parts needed to convert from a gas-powered engine to an electric motor setup, which is convenient for locations where gas engines are restricted or electric power is preferred. 

Q5. What would require replacing the “Belt Guard Assembly” or “Lift/Tilt Assembly”?

These are structural/safety-related components; replacing them becomes necessary if the belt guard is damaged (exposing moving components) or if the lift/tilt mechanism is no longer holding the spray arm properly, which could compromise operator safety or machine stability.
