Key Features
✅ Robust Connection—A robust structure seamlessly connects two pipes of the same diameter, ensuring the connection strength is no less than that of the pipe itself.
✅ Double Sealing—Precision-machined internal threads at both ends engage with the external threads of the pipe at two points, forming a reliable sealing barrier and effectively preventing leakage.
✅ High-efficiency corrosion protection – A dense blackened surface layer provides excellent rust and corrosion protection, adapting to various environments and ensuring long-lasting durability.
✅ High versatility – Standard thread specifications, suitable for connection needs of various metal pipes of the same diameter (such as galvanized pipes and iron pipes).
✅ Easy installation – No special tools required; installation can be completed quickly using standard pipe wrenches, significantly improving construction efficiency.
Applications
• Straight extension and splicing of various metal pipes
• Repair and connection of damaged pipe sections
• Installation of valves, instruments, and other equipment in existing piping systems
• Installation and maintenance of building water supply and drainage, fire protection, and industrial piping systems
Quality Commitment
This product is manufactured strictly according to national pipe fitting standards. Each piece undergoes rigorous dimensional tolerance, thread accuracy, and pressure testing to ensure a stable connection and durable seal, making it a reliable pipe "connecting link."
Installation Tips: Before installation, ensure that the external threads of both pipe ends are intact and of appropriate length. It is recommended to evenly wrap Teflon tape or apply sealant to the external threads of the pipe, screw the pipe into both ends of the pipe clamp, and tighten them evenly in opposite directions using a double wrench to achieve the best sealing effect.
