Tokyo Hoshikawa Shower Hose 150cm Stainless Steel #STAR★Bulk purchase welcome ╰(*´︶`*)╯♡ [Unused] For those who understand home storage, Thank you very much. [Excellent Durability] The connection part of the shower hose is made of A-grade forged brass, precisely processed, and is sturdy and highly durable. The screw size is international standard G1/2 (equivalent to Japan PJ1/2), making connection easy!! The combination of a stainless steel outer tube and a PVC inner tube makes the hose both lightweight and durable. [Applicable Mixer Tap Manufacturers] The screw size on the side connecting to the mixer tap is G1/2. This product can be installed directly on LIXIL (INAX), SAN-EI, and MYM mixer taps. *Excluding LIXIL (INAX) balance釜, two-bubble shower mixer taps, and switch shower mixer taps. [Applicable Shower Head Manufacturers] The screw size on the side connecting to the shower head is G1/2. This product can be directly installed on TOTO, LIXIL (INAX) *excluding balance釜, SAN-EI, and KAKUDAI shower heads. Some shower heads may fit the screw size, but the o-ring at the base of the head may get in the way and prevent connection! In that case, remove the o-ring at the base of the shower head. If water leaks after removing the o-ring, try adding the included packing. [Mixer Tap Manufacturers Requiring Adapters] TOTO "Thick hose (W24 mountain 20), Thin hose (W19 mountain 24), TOTO resin elbow", KVK, INAX balance釜, Tokyo Gas, Rinnai, Mizutani, and Osaka Gas water taps cannot be installed directly, so an adapter is required. This product does not include an adapter, so please purchase one separately. [In case of water leakage] * Please connect with the packing (transparent rubber ring) inside the stainless steel shower hose body still attached. Correctly installing the seal ring can prevent water leakage. * Depending on the shower head, it may be possible to prevent water leakage by attaching two packings between the hose and the shower head, but in that case, it may be difficult to rotate the nut.
