Compatible replacement for TKS05310J: Swivel, Water-Saving Aerator Shower Adapter Nozzle This is a "compatible replacement." Please understand that this is NOT a "genuine product" before considering your purchase. The TKS05310J does not have a swivel function, and the water outlet angle is limited. However, the 100-yen shop aerators don't fit, and the genuine products are expensive... This is a product I requested from a business partner because of such a problem in my home. Other compatible products often have problems such as not fitting the specifications or causing water leaks, but this has been tested and confirmed to work, so you can use it with confidence. The swivel function is available on both the faucet side and the aerator side, allowing you to adjust the angle on each. You can choose between "shower" and "normal" water outlet. (You can select by twisting the aerator) 【Installation Method】 ① Remove the water outlet nozzle on the TKS05310J side with a coin, etc. (Image 3) ② Connect the wide side of the included adapter to the faucet (Image 4) ③ Connect the aerator body to the narrow side of the adapter (Images 5-6) ※ Regarding the condition, although it is an unused item, I will lower the condition by one level because I will check the water outlet with my TKS05310J at home before shipping. 【Color】 Silver (Black is sold separately) 【Included Items】 Conversion adapter for TKS05310J 【Packaging】 As mentioned above, this is not a commercial product, so it will be bulk-packaged (wrapped in bubble wrap) and shipped anonymously. 【Important Notes】 I have not tested the connection and water outlet with anything other than TKS05310J. Also, I will check the water outlet with the above equipment before shipping, so please refrain from reflecting incompatibility or usability issues in the seller's evaluation. Thank you.
