I'm sourcing flexible hoses for transporting HOCL using a water reel, and I'm particularly interested in options that feature a PTFE convoluted tube. I'd like it to have a coating made of PVC or urethane for added durability. It's important for me to avoid any metal materials such as SUS304 in the construction, as I believe they may corrode when in contact with HOCL. For the specifications, I'm looking for a hose with an inside diameter around 15mm and lengths of either 10m or 15m. The connectors should include a straight male thread (PT1/2") and a 90-degree angle male thread (PT1/2"), preferably made from PVDF. The design should allow the hose to be easily wound around the water reel.
