Metal Clamp Connector
SKU: 7521, 8370
Category: Piping & Fluid Transfer Components
Overview
The Metal Clamp Connector provides a quick and economical solution for nozzle and component installation on piping systems. Designed for applications where threaded connections are impractical or unavailable, this connector requires only a simple drill operation and bolt tightening for secure installation.
Key Features
- Thread-Free Installation – Eliminates the need for screw thread jointing, enabling installation on sustain pipes without pre-threaded sections
- Steel Construction – Connector body manufactured from steel bar with selectable outlet joint sizes
- Embedded Pipeline Design – Entrance can be embedded directly into the pipeline, minimizing deposit accumulation and reducing blockage risk
- Secure Retention – Prevents connector displacement after nozzle installation through integrated clip button design
- Reliable Sealing – DingQing rubber cushions provide superior air-proof conditions and material erosion resistance
Design Advantages
- Quick installation without specialized threading equipment
- Flexible outlet connection options (NPT or BSPT)
- Reduced maintenance requirements due to embedded design
- Durable construction suitable for industrial piping applications
- Minimal pressure drop and flow restriction
