尼日利亚采购需求：黄铜接头、软管倒钩、内螺纹管、封闭式螺纹接头、喇叭口接头、推入式接头

I'm looking to procure some specialized fittings and tubes. First, I need a thermoplastic capillary tube with specific dimensions and a brass fitting. The wall thickness and end connection details are essential, as this will be for a particular application. Quantity required is 16 pieces. Additionally, I'm in need of a couple of reducers, one to transition from a smaller to a larger diameter and the other with the reverse configuration. Both need to meet certain pressure ratings and be made from brass, with the right manufacturing process and sealing type. I also require a union fitting in brass for seamless connections. Please confirm availability and lead times for these items. Total quantities are 6, 8, and 4 for the respective components. Looking forward to your prompt response!
