Industrial Clamps
GRIP-L Clamp – Axial Restraint Pipe Coupling Clamp
The GRIP-L Clamp, technically known as an Axial Restraint Pipe Coupling Clamp, is a stainless steel pipe repair and coupling solution designed for high-pressure and critical applications. Unlike standard pipe repair clamps that only provide sealing, the GRIP-L Clamp delivers both leak-proof sealing and axial restraint, ensuring the pipe ends are securely gripped and prevented from axial movement. This dual functionality makes the GRIP-L Clamp a preferred choice in oil & gas, water supply, chemical processing, marine, and power plant industries, where pipeline safety and reliability are essential.
Features of Clamps
- Dual function design: Provides sealing + axial restraint
- High strength SS304/SS316 body for durability and corrosion resistance
- 360° leak-proof sealing with EPDM/NBR gaskets
- Withstands surge pressure and mechanical loads
- Quick bolt-on installation without welding or hot work
- Reusable and long-lasting, service life up to 25 years
