Durability and protection - Wear-resistant, corrosion-resistant and rust-resistant with strict process control from component to finished product assembly. Easy installation and reliable sealing - Clean, burr-free threads for convenient and fast installation, with strong sealing performance. Quality materials and protection - Excellent material selection with rust protection surface treatments, durability, and improved corrosion resistance. Leak-free performance - Rotation without air leakage, thickened sealing rubber O-ring to enhance sealing performance and suppress air leaks. Use scenarios - Hydraulic or pneumatic systems that require leak-tight connections and long-term durability. - Automotive or industrial equipment assemblies where quick installation and reliable corrosion resistance are important. - Water, coolant, or oil handling systems where air leakage must be minimized and corrosion protection is required.
