Double bolt clamp A double bolt hose clamp is a type of heavy-duty clamp designed to secure hoses—especially large-diameter or high-pressure hoses—in industrial, agricultural, or heavy equipment applications. It features two bolts (usually on opposite sides) that are tightened to compress the clamp evenly around the hose, providing a very strong and reliable seal. 🔩 Key Features: Double-bolt design: Allows for even pressure distribution and increased clamping force. Wide band: Typically wider than standard clamps for better grip and sealing. High-strength construction: Usually made of stainless steel, galvanized steel, or plated carbon steel for corrosion resistance and durability.
