Storage & logistics

Proper storage of remanufactured injectors is critical to maintaining their performance until installation. Keep them in a dry, temperature-controlled environment away from direct sunlight and contaminants. Avoid stacking heavy items on top of the packaging to prevent deformation or damage to the injector's delicate components. For bulk orders, use sturdy shelving units and label each batch clearly to ensure easy identification and rotation based on expiry or usage frequency. Always handle injectors with clean, dry hands or gloves to prevent contamination, and store them in their original packaging until ready for use.
