Quicksilver 8M0128419 — DOT 5 Brake Fluid | 12 oz | Meets MIL-PRF-46176 & MIL-PRF-46176B | Marine & Powersport

Quicksilver 8M0128419 is a silicone-based DOT 5 brake fluid for marine and powersport applications requiring DOT 5 fluid. Important: DOT 5 is not compatible with DOT 3 or DOT 4 brake fluid systems — do not mix. DOT 5 is silicone-based; DOT 3 and DOT 4 are glycol-based. Mixing them causes brake system damage. Verify your system requires DOT 5 before ordering. Quicksilver 8M0128419 meets or exceeds MIL-PRF-46176 and MIL-PRF-46176B military specifications, provides low compressibility for consistent braking, and includes corrosion protection to help extend brake component life. Using this product does not void manufacturer warranties where DOT 5 fluid is specified. Sold as a single 12 oz bottle.

Confirm Fitment Before Ordering

Confirm your system is a DOT 5 application before ordering — check your owner’s manual or contact us by email, text, or live chat. Do not add DOT 5 to a system containing DOT 3 or DOT 4 fluid.

Frequently Asked Questions

Q: What is the difference between DOT 5 and DOT 3 or DOT 4 brake fluid?
A: DOT 5 is silicone-based and does not absorb moisture. DOT 3 and DOT 4 are glycol-based and do absorb moisture over time. They are chemically incompatible — mixing DOT 5 with DOT 3 or DOT 4 causes gel formation and brake system failure. Always confirm which specification your system requires before adding fluid.

Q: What marine applications require DOT 5 brake fluid?
A: Some Mercury and Quicksilver power steering, tilt/trim, and braking systems on older sterndrives and specific powersport applications specify DOT 5. Check your owner’s manual or Quicksilver service documentation for your specific model to confirm DOT 5 is required before ordering.

Q: What mil-spec does Quicksilver 8M0128419 meet?
A: Quicksilver 8M0128419 meets or exceeds MIL-PRF-46176 and MIL-PRF-46176B military performance specifications for silicone-based brake fluid.

Q: Can I use Quicksilver 8M0128419 in automotive brake systems?
A: Quicksilver 8M0128419 is formulated for marine and powersport DOT 5 applications. If your automotive system is specified for DOT 5, it meets the same MIL-PRF-46176B standard, but confirm with your vehicle manufacturer before use.

Q: How much DOT 5 brake fluid does one bottle contain?
A: Each bottle of Quicksilver 8M0128419 contains 12 ounces of DOT 5 brake fluid.
