Center Punch Hose Clamps

Center Punch Hose Clamps are a specialized type of clamp known for creating a strong, low-profile, and tamper-evident connection on hoses and fittings. Unlike traditional worm gear clamps that are adjusted with a screw, these clamps are installed using a dedicated center punch tool that tensions the band and then punches and deforms the buckle to create a permanent, secure lock.
Product Details

This unique installation method results in a smooth, snag-free outer surface, reducing the risk of entanglement. The permanent crimp formed by the center punch tool provides a clear visual indication of tampering, making them ideal for applications where security and integrity of the connection are crucial.

Typically manufactured from durable materials like stainless steel or galvanized steel, Center Punch Hose Clamps offer good corrosion resistance and reliable performance in various industrial, agricultural, and automotive applications, particularly in low to medium-pressure systems where a robust and tamper-evident seal is required.

Features

  • Tamper-Evident Seal: The crimped buckle provides a visual indication if the clamp has been tampered with or removed.
  • Low Profile: The design results in a smooth outer surface without a protruding screw housing, reducing snag hazards.
  • Secure & Permanent Connection: Installed with a center punch tool to create a strong, non-adjustable, and reliable seal.
  • Durable Construction: Commonly made from stainless steel or galvanized steel for good corrosion resistance. 
  • Even Clamping Force: The banding system distributes pressure evenly around the hose for a secure fit.
  • Requires Special Tool: Installation necessitates a dedicated center punch clamp tool.

  • Technical Data
