How about Ryder trough fittings?

Ryder tank fittings are very good. Ryder is the leading enterprise of grooved pipe fittings in China. Leading the development of the industry with leading technology and specialization, and participating in the drafting and formulation of seven national and industry standards. The company successfully applied the self-sealing technology of grooved pipe fittings to the development of soft sealing valves. Self-sealing series valve products have formed a group of invention patents, representing the product self-sealing mid-line butterfly valve, which was selected as the 40th anniversary of reform and opening-up by China Machinery Industry Federation as an excellent product in the machinery industry. Since its establishment, Ryder has always adhered to the road of independent innovation. After nearly 20 years of development, we have been deeply cultivating and focusing on the research and development of self-sealing intelligent pipeline valves. The company has scientific research and innovation platforms such as Shandong Trench Pipe Fitting Engineering Technology Research Center and Weifang Fluid Self-sealing Engineering Laboratory. It is a graduate workstation of Shandong University, Weifang Enterprise Technology Center, Weifang Key Laboratory of Pipeline System, Weifang Pipeline and Valve Engineering Laboratory, Weifang Industrial Design Center and Weifang Fluid Self-sealing Engineering Technology Research Center. With domestic invention patents such as self-sealing mid-line butterfly valve, elastic self-sealing gate valve, self-sealing swing soft-sealing check valve, self-sealing globe valve and self-sealing eccentric semi-ball valve, as well as five national invention patents, it is the leader of domestic fluid self-sealing technology trend.
