Kuriyama Kuri Tec® Endure™ 251 Air Brake Tubing is crafted with a high-performance polyester compound for superior flexibility and durability in extreme environments. Operating at pressures up to 150 psi and temperatures from -85°F to 200°F, this tubing resists cracking, heat aging, and oil exposure, outlasting traditional nylon tubing. Its UV stabilization and thermoformable design make it easy to install in tight corners, ensuring reliability in truck, bus, trailer, and auxiliary air brake systems.
