1/4 Inch Hydraulic Brake Hose Coil for Pickups and Vans JUNZE
Most brake hose coverage stops at the two smaller bores. The 1/4 inch size is where light commercial work begins — pickups carrying real loads, vans with long wheelbases, and the light trucks that behave somewhere between a van and a truck.
The JUNZE 6.3mm coil holds a 6.45mm ±0.15 actual ID inside a 15mm outer diameter, wall at 3.65mm, with the multi-strand fiber braid carrying a 50 MPa burst minimum under SAE J1401.
Workshops serving mixed fleets usually run this roll next to the 3/16 inch one. Between the two bores, most of a light commercial customer base is covered.Product Details

Product Information
Expansion at this bore runs 2.69 ml/m under 6.9 MPa and 3.84 ml/m under 10.3 MPa — catalog-tested values, higher in absolute terms than the small bores because a wider tube holds more volume, and consistent enough to calibrate a crimp process against.
The fiber braid contributes the tensile strength behind the burst rating; the cover handles ozone and weathering, which matters for light commercial vehicles that spend their lives parked in the open between jobs.
