【Product Description】 ・Replacement hose (tube) for Panasonic Oral Irrigator Doltz. ・This listing is for the hose only (the main unit is not included). ・Hoses can tear and leak water with age. Repair costs from Panasonic, the manufacturer, are around 11,000 yen. ・Also, genuine replacement parts cost over 3,000 yen. This is a part for when you only want to replace the hose. ・Replacement hoses that are curled like the original products (compatible products) may have strength issues due to the stress of stretching and curling. If you are replacing it, we recommend prioritizing strength. (Our products clearly indicate hose strength.) With strong products, using them straight without curling will make them last longer. ・There are many replacement methods available online, so please search and use them (replacement work is at your own risk). The photo shows the hose of a Doltz EW-DJ61 that has been replaced. It has been used without any problems for about 2.5 years after replacement. There are no tears causing water leaks at all (after 2.5 years). 【Product Specifications】 ・Manufacturer 　Reliable Made in Japan (industrial parts). ・Size 　Outer diameter: 4mm, Inner diameter: 2.5mm, Length: approx. 1.0m ・Material 　Urethane ・Pressure resistance (maximum working pressure) - a guide to strength during use Compressed air: 0.8MPa, Water: 0.3MPa 【Other】 ・This compatible part is believed to be applicable to most Doltz models that have a hose, but please confirm compatibility and the results of the replacement yourself and at your own risk. ・When you search online, the manufacturer, of course, does not recommend replacing the hose yourself. They recommend expensive manufacturer repairs. Replacement is at your own risk. ・Please refrain from price negotiations.
