Heavy duty equipment engines operate using multiple belts, called V-belts. These belts run off the engine’s crankshaft pulley to drive multiple peripheral devices such as; the alternator, air conditioning compressor, power steering pumps, air compressor pump and water pumps. Al-Asfar V-Belts are engineered to run maintenance-free to keep your equipment operating without the need for re-tensioning. Al-Asfar offers a variety of Engine and Air Brake hoses. The hoses meet either SAE 100R5 and SAE J1402 standards. They are used in a wide range of engine and brake applications such as medium pressure petroleum based hydraulic service; air and water service; lubrication oils and diesel fuel service. Temperature range from -40C to +70C.
