New, unused Purchased from Amazon Although new and unused, there is discoloration on the inside of the connection part, as shown in the image. Brand: Hoshikawa Polyvinyl chloride (PVC) Length: 200cm [Excellent Durability] The connection part of the shower hose is precisely processed with A-grade forged brass, making it sturdy and highly durable. The screw size is the 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 allows the hose to be 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 directly attached to mixer taps from LIXIL (INAX), SAN-EI, and MYM. *It can be installed on all except LIXIL (INAX) balance kettles, 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 is compatible with TOTO and LIXIL (INAX) shower heads. *Not compatible with balance kettles. It can be directly attached to SAN-EI and Kakudai shower heads. Some shower heads may have the correct screw size, but may not connect due to the O-ring at the base of the head. In that case, remove the O-ring from the base of the shower head. If water leaks after removing the O-ring, add the included packing. [Mixer Tap Manufacturers Requiring Adapters] Since this product cannot be directly attached to water taps from TOTO ("thick hose (W24 mountain 20), thin hose (W19 mountain 24), TOTO resin elbow"), KVK, INAX kettle, Tokyo Gas, Rinnai, Mizutani, and Osaka Gas, 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 body of the shower hose still attached. Correctly installing the seal ring can prevent water leakage. *Depending on the shower head, water leakage may be prevented by attaching two packings between the hose and the head, but in that case, it may be difficult to rotate the nut.
