Polaris DOT 4 Brake Fluid 12 oz — High-Temp Hydraulic Fluid for Snowmobiles & UTVs

Polaris DOT 4 Brake Fluid is a purpose-built high-temperature hydraulic fluid in a 12-ounce bottle that preserves brake responsiveness and protects components in Polaris snowmobiles, UTVs, and SxS vehicles.

Keep your Polaris off-road machine stopping precisely when you need it with a brake fluid engineered to meet the demands of cold starts, trail heat, and repeated heavy braking. This DOT 4 formula is developed and tested by Polaris engineers to lubricate seals and lines, resist thermal breakdown, and reduce corrosion inside the braking system. The compact 12 oz bottle (part 2872189) makes it easy to top up the master cylinder or carry as a service spare on longer rides.

How does this brake fluid preserve brake lever feel?

The Polaris DOT 4 fluid maintains hydraulic pressure and lever sensitivity by resisting vapor formation at higher temperatures. Fewer vapor pockets mean a firmer pedal and more consistent stopping power throughout a ride. It also conditions rubber seals to reduce swelling and sticking that can dull lever feedback.

• Higher boiling point than DOT 3 for reduced vapor lock risk
• Lubricates O-rings and rubber lines for smoother lever action
• Stable viscosity preserves feel across temperature swings

What protections does the formula offer for brake system parts?

Polaris DOT 4 contains anti-corrosive additives that help limit rust and degradation inside metal components. That protection, combined with thermal stability, extends the service life of calipers, master cylinders, and lines when used as recommended. Regular fluid replacement prevents contaminant buildup which can accelerate wear.

• Anti-corrosive agents reduce internal part deterioration
• Thermal stability minimizes fluid breakdown under load
• Engineered to work with Polaris brake materials and seals

How should I use and store the 12 oz bottle on my Polaris vehicle?

Use the bottle to top off or replace fluid in hydraulic brake systems following vehicle service intervals and Polaris recommendations. Store the bottle tightly capped, upright, and away from moisture to prevent contamination. Dispose of used fluid and rags responsibly per local regulations.

• Ideal for topping off master cylinders and small drain-and-fill jobs
• Keep cap sealed to prevent moisture absorption
• Follow Polaris service instructions for bleed and fill procedures

Why choose Polaris-branded brake fluid over generic options?

Polaris DOT 4 is formulated and validated alongside Polaris vehicle designs, ensuring compatibility with the materials and performance expectations of their off-road models. Using the factory-engineered fluid reduces the risk of seal incompatibility and helps maintain warranty and performance standards. It’s a straightforward way to match the product specification Polaris used in testing.

• Developed and tested by Polaris for its vehicles
• Meets performance profiles expected in Polaris service procedures
• Available in a convenient 12 oz size for easy maintenance

Who is this for: Polaris DOT 4 Brake Fluid, 12 oz (part 2872189) is intended for Polaris owners and technicians who service snowmobiles, UTVs, and side-by-sides and want a factory-engineered fluid that supports consistent braking performance and component longevity. It’s suited to riders who perform regular maintenance, mobile mechanics who need a compact spare, and anyone replacing fluid to maintain safe, predictable stopping while operating off-road machines.
