Single Bolt Clamps

Rubber Hose

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

Benefits & Advantages

Quick Installation

  • Single bolt mechanism simplifies setup, minimizing labor and downtime on the job site

Durable & Reliable

  • Withstands vibration, moderate pressures, and environmental exposure common in dewatering tasks

Cost-Effective

  • Typically cheaper than more complex multi-bolt or specialized clamps, reusable if properly maintained

Versatile

  • Fits a wide range of hose diameters, making it a versatile stock item for contractors

Adaptable to High Moisture

  • Galvanized or stainless steel variants resist rust in wet or muddy conditions
