Product Details

The Dorman H621388 is a direct-fit replacement brake hydraulic hose engineered to restore proper hydraulic pressure and pedal feel to your vehicle's brake system. Manufactured to match the original hose's dimensions, end fittings, and routing path, this hose installs in the same position as the factory unit with no modifications required.

Key Features:

  • Ideal OEM Replacement – Precision-engineered to match the fit, function, and performance of the original brake hydraulic hose
  • Position-Specific Design – Manufactured to precise measurements for an exact fit and straightforward installation
  • Durable EPDM Rubber Construction – Built with EPDM rubber body and specially coated, corrosion-resistant end fittings for long-lasting performance
  • Government-Regulated Safety Standards – Materials tested to exacting safety and durability requirements
  • Pressure Tested – Hoses are tested up to 4,000 PSI to verify safety standards are met before leaving the factory
  • Fully Assembled – Ready to install right out of the box

Brake hose replacement is recommended as part of a complete brake service. A deteriorated or internally collapsed hose can restrict fluid flow, cause uneven braking, or lead to brake fluid loss. The Dorman H621388 delivers a reliable, cost-effective solution compared to dealer pricing, without sacrificing quality or safety.

Flexible Hose

Very high level of responsive customer service, wow! And the items arrived immediately, so fast I thought there might be a mistake. :D<br>thx Sean!

My first order and I must say, very impressive! Awesome prices and super-fast shipping direct from the manufacturer. Couldn't ask for more! I will return.

Great website

This was my first order with Autoplicity. Their prices were great, and the ordering process very easy. I was a little frustrated at first, as the order didn't arrive as expected. When I called, it took a little work, but I finally got the info that it was shipping from the manufacturer, and did get the tracking info. The parts arrived when tracking said it should. Would I place another order with Autoplicity? Short answer is yes!

Purchased K&N Filter. Excellent price and received filter as scheduled.
