Hose that transfers the water heated by engine to radiator and then transfers the water back to engine to cool down the engine.
Hose that transfers the water heated by engine to heater to increase the indoor temperature and transfers the water back to the engine.
Functioning as a duct connecting fuel inlet for gasoline and diesel to fuel tank.
By adopting materials with excellent oil proofing, weatherproofing, etc., THV hose with enhanced fuel penetrability-proofing are developed and being delivered according to the reinforced recent environment laws.
It is the hydraulic hose delivering oil pressure from power steering pump to the gear box, with durability and high tear resistance, structure of which to absorb surge pressure and noise.
