Clamp Type Rubber Joint
Clamp Type Rubber Joint
The clamp type rubber joint, also referred to as a hose-end rubber connector or quick-fit rubber expansion joint, is a flexible coupling designed for low-pressure piping systems where quick installation and maintenance are required. Instead of traditional flange connections, this joint uses stainless steel clamps or hose clamps to secure the joint ends to pipes, allowing for fast assembly without welding or bolting.
Widely used in building water systems, HVAC, irrigation, drainage pipelines, and temporary piping setups, the clamp rubber joint is valued for its easy installation, cost-effectiveness, and high flexibility. It is ideal for absorbing vibration, reducing noise, and compensating for minor axial and lateral displacement in short-distance pipeline sections.
Manufactured from premium EPDM, NBR, or Neoprene rubber and reinforced with nylon fabric or steel wire layers, the clamp type joint ensures corrosion resistance, tensile strength, and reliable sealing performance. It is available in a range of diameters and compatible with common clamp sizes used in industrial and civil applications.
