Product Details

The Dorman H621978 is a direct-fit OE replacement brake hydraulic hose engineered to restore proper hydraulic pressure and reliable braking performance. Built to match the original equipment hose in fit, form, and function, this hose is position-specific and manufactured to precise measurements for a straightforward, hassle-free installation.

Key Features:

  • Precision-engineered fit – manufactured to exact OEM specifications for a position-specific, drop-in replacement
  • EPDM rubber construction – provides excellent resistance to heat, ozone, and brake fluid degradation for long-lasting durability
  • Corrosion-resistant fittings – specially coated end fittings help prevent rust and ensure a leak-free connection
  • Pressure tested – each hose is tested to up to 4,000 psi to confirm it meets government-regulated safety and durability standards
  • Fully assembled – ready to install right out of the box; banjo-style configurations include new copper sealing washers where applicable

Replacing worn or cracked brake hoses is a critical part of any complete brake system service. A deteriorating hose can cause spongy pedal feel, brake fluid loss, or brake drag. The Dorman H621978 restores consistent hydraulic flow between the hard brake lines and the calipers or wheel cylinders, helping maintain safe, confident stopping power.

I would like to have used Paypal (not the credit card) but could not.

Definitely the best price online. The website search function could stand to be better, but I was able to find the product I was looking for eventually and again, the price was unbeatable!

Fast ordering process

Mui bien

Quick and easy!

Before I buy any auto part I check prices at Autoplicity. Almost always the price is significantly lower than anywhere else: Rock Auto, Summit, Jegs, etc... <br><br>Do yourself a favor and check their prices prior to your next purchase and save yourself some money.

Very easy

Placed order #27494 for some bumpstops. Came out $40 cheaper then i could get with reseller discounts elsewhere. Great item, shipped quick, very satisfied.

Great service, and prompt delivery. I would order again and recommend them to my friends.

First time buyer from Autoplicity and found the website easy to navigate and find what I wanted quickly. They had the best price of all the other sites I checked, including shipping.
