Precautions for use
Before connecting tubing to a fitting, ensure that the tubing is cut vertically and that there are no nicks or damage to the outer surface.
Fittings and tubing are recommended for use in drinking water dispensers. When applying to specifications other than those, please contact Stormtec Co., Ltd. before use.
Before disconnecting the tubing from the fitting, make sure the equipment is de-pressurized.
Be careful not to fold or bend the tubing excessively. Excessive strain may cause water leakage or other defects.
When disconnecting tubing, it is recommended to use a fitting spanner.
Stormtec guarantees the quality of its products for 2 years. For hygiene and safety reasons, please maintain a replacement cycle of less than 2 years.
Make sure to cut off any tubing parts that have scratches or damage on the surface before using.
