Single Bolt Clamps
Overview
Single Bolt Clamps (often referred to as Band Clamps or Hose Clamps) are designed to secure hoses—particularly suction and discharge lines—onto fittings or couplings. Constructed from high-strength materials (usually galvanized or stainless steel), these clamps enable a tight, leak-resistant connection in dewatering, construction, and general fluid transfer setups.
Key Uses & Applications
Dewatering & Drainage
- Securing suction hoses to pumps or couplings for groundwater or trench dewatering
- Used in wellpoint headers, discharge hoses, or manifold lines
- Ensures leak-free operations
Construction & Earthworks
- Fastening lay-flat hoses or rigid piping in temporary pump installations
- Adjusting hose lengths or relocations on busy job sites
- Minimal downtime during adjustments
Municipal & Emergency
- Tightening and stabilizing temporary water transfer hoses
- Quick assembly/disassembly for rapid deployment
- Effective for flood mitigation scenarios
Industrial & Mining
- Attaching large-diameter hoses for slurry and wastewater
- Suitable for dredging applications
- Withstands moderate pressures in pumping operations
Agricultural & Irrigation
- Clamping irrigation lines onto barbed or beaded pipe fittings
- Ensures robust connections for variable terrain
- Tolerates movement in agricultural settings
Product Features
High-Strength Metal Construction
- Typically galvanized steel or stainless steel band for corrosion resistance
- Resists rust and damage in damp environments
- Withstands exposed outdoor conditions
Single Bolt Tightening Mechanism
- Quick, straightforward installation—just one bolt to tighten
- Minimal tools required; usually a single socket or wrench
- Provides uniform compression around the hose
Wide Clamping Range
- Available in multiple diameters to fit hoses from 1" to large industrial sizes
- Accommodates varying hose thicknesses
- Suitable for reinforced suction hoses
Low Profile Design
- Slim band profile reduces interference in confined spaces
- Less chance of snagging or catching on adjacent equipment
- Ribbed or perforated pattern for better friction
