  • Black EPDM rubber outer hose for flexible routing

Detailed Product Information

This Dorman brake hose is built as a direct replacement for select Nissan 370Z, INFINITI Q70, Q70L, QX50, Q60, Q40, EX37, G37, M37, M56, EX35, and G25 models in the listed front-left inner, front-left, and front-right inner positions. The hose measures 10.55 inches overall, with axis lengths of 11.34 and 9.53 inches, and uses an M10 x 1.0 female connection on one end with a junction-style treated steel fitting on the other. Dorman H621972 is a practical choice when replacing a worn or damaged brake hose on a Nissan 370Z or INFINITI brake system that requires the correct hose shape and connection style.

This part cross-references Centric Parts 150.42150 for the same application.

What This Brake Hose Helps Address

  • Brake fluid leaks from a cracked or deteriorated hose
  • Soft or inconsistent brake pedal feel caused by hose wear
  • Brake hose damage from age, heat, or road exposure
  • Restricted fluid flow from an internally weakened hose
  • Service needs during front brake repair on listed Nissan and INFINITI models

Installation Notes and Tips

Verify the vehicle position before ordering, since this hose is listed for front-left inner, front-left, and front-right inner applications depending on model and year. Confirm the end fitting style, thread size, and hose length against the original part before installation. Mounting hardware, brackets, gaskets, and seals are not included, so reuse or replace those components as needed during brake service. After installation, bleed the brake system according to factory procedure and inspect all connections for leaks.

Quality Assurance

Dorman engineers this brake hydraulic hose to match original fit, function, and performance on the specified vehicles and positions. The EPDM rubber hose construction and treated steel fittings support durable service in a brake repair environment.
