You are looking at a Brand New Weh Fill Receptacle for Automotive use for Hydrogen Fuel cell applications. This is rated at 35MpA or approx. 5,000 PSI. This is the lower of the two pressure ranges for vehicle application but Fuel Cell Tugs (Plug Power), and other vehicles use the 5,000 PSI fill receptacles. This is not the 10,000 PSI or 70 MpA receptacles that are used on Honda Clarity, or Toyota Mirai and Hyundai Nexo vehicles. The fuel line tube size for this receptacle is 3/8" Tube. This item is in its original bag, only just opened the bag to take pictures of it. I have only two left.
