Are your products compatible with my vehicle?

Many parts are universal and every product page lists detailed specifications including size, flare type, and thread. For vehicle-specific solutions, check our RightQuick kits or contact us with your year, make, and model for assistance.

What materials do your brake lines and fittings come in?

We offer copper-nickel (NiCopp), stainless steel, PVF-coated or galvanized steel, and rubber where applicable. NiCopp is easy to bend and flare while offering high corrosion resistance. Stainless steel provides maximum durability. PVF-coated steel is an OE-style, budget-friendly option.

Do you offer complete brake line kits?

Yes. We offer both vehicle-specific and universal brake line kits. RightQuick kits bundle tubing, fittings, and on select kits, installation tools to make installation easier.

What brake line size and flare type do I need?

Most North American vehicles use 3/16 inch (4.75 mm) brake line, while some trucks or specific circuits use 1/4 inch. Common flare styles include SAE Double or Inverted (45 degree) and ISO or Bubble (DIN). Always match the replacement line, fittings, and flaring tool to your vehicle’s original specifications.

Are your lines and fittings DOT compliant?

Our hard lines and fittings meet or exceed applicable SAE and DOT specifications when properly installed and flared according to manufacturer guidelines.

Do you provide installation instructions?

Yes. Many products include installation guides, and we are continually expanding how-to resources in our Knowledge Garage. If you need additional support, contact us directly.

What tools do I need for a leak-free install?

You will need a quality tubing cutter, deburring tool, proper flaring tool (SAE or ISO), and a tubing bender. Ensure cuts are square and deburred, use the correct die and depth, torque fittings to specification, then pressure-bleed and check for leaks before driving.

Can I talk to someone about a custom solution?

Absolutely. Email hello@4lifetimelines.com or use our contact form with your specifications including year, make, model, VIN if available, line size, flare type, and thread.

What payment methods do you accept?

We accept all major credit cards, Shop Pay, Google Pay, and Apple Pay.

What warranty do 4Lifetime products include?
