Straight connectors are typically simple through-type fittings with open ends on both sides, allowing direct connection to other piping components or equipment. They have a relatively simple structure without complex thread or snap designs, offering reliable connections and good sealing performance. This product is suitable for straight pipe connectors in oil- and gas-based piping systems and is widely used in industries such as petroleum refining, chemical processing, light industry, textiles, defense, metallurgy, aviation, and shipbuilding. It is also applicable to hydraulic transmission piping systems in various mechanical engineering and machine tool equipment.
