巴基斯坦采购需求：压力调节器、泄压阀、快速接头、管接头、管道接头、歧管

I'm looking to source some specific components for our project. First, I need needle valves with a 1/4 NPT connection that can handle an operating pressure range of 12000 to 15000 psig. These valves are crucial for our system's performance, so quality and reliability are essential. Additionally, I'm interested in breakaway or quick couplers available in 1/4” and 1/2” sizes, also rated for similar high pressures. Lastly, I require flexible pipes with a 1/4” diameter and a length of 7 feet that meet the same pressure specifications. Please provide details on your availability, pricing, and lead times for these products. Thanks!
