Our Reduced Coupling provides a versatile, cost-effective solution for securely joining two pipes of different diameters, ensuring reliable performance across plumbing, irrigation, HVAC, and industrial fluid-handling systems. Manufactured from premium-grade materials—including ductile iron, 316-series stainless steel, or UV-stabilized polypropylene—each coupling delivers outstanding corrosion resistance, mechanical strength, and longevity, even in harsh environments.
At the heart of its design is a precision-machined reducer body that smoothly transitions flow from a larger pipe to a smaller one. Dual high-tensile stainless-steel clamp bands wrap around EPDM or NBR gaskets, creating a uniform, leak-proof seal capable of withstanding pressures up to 16 bar (232 psi). This integrated gasket system offers excellent chemical compatibility, making the coupling suitable for potable water, wastewater, agricultural chemicals, and most process fluids.
Key Features & Benefits:
-
Wide Diameter Compatibility: Connect pipes ranging from 50 mm down to 20 mm (custom sizes available) to adapt legacy systems, branch off mains, or connect instrumentation ports without custom fabrication.
-
Enhanced Flow Efficiency: Unlike rigid reducers that introduce turbulence and pressure drop, our tapered interior profile maintains consistent flow dynamics, reducing energy consumption in pumping systems.
-
Robust Construction: Corrosion-proof materials and UV-resistant coatings handle salt spray, temperature cycling, and mechanical shock, delivering maintenance-free service in outdoor or underground installations.
-
Tool-Free, Rapid Installation: No welding, solvent bonding, or hot work is required. Simply slide each end over its respective pipe, align the bodies, and tighten the clamp screws for an instant, pressure-rated seal.
-
Reusability & Adjustability: Loosen the clamps to reposition or reuse the coupling as system layouts change, minimizing downtime and spare-parts inventory.
-
Standards Compliance: Meets or exceeds ISO 8434-1, EN 12627, and ASTM D3261 performance criteria for transition fittings.
Applications & Use Cases:
-
Residential & Commercial Plumbing: Adapt main supply lines to smaller branch circuits under sinks, behind walls, or in utilities closets.
-
Agricultural Irrigation: Branch off drip-irrigation mains to lateral lines without the need for custom reducers or fused joints.
-
Industrial Processing: Connect sensor housings, sampling probes, and process drains to main piping with a reliable transition that resists harsh chemicals.
-
HVAC & Compressed-Air Systems: Manage airflow and condensate lines in equipment cabinets with minimal installation space.
Whether you’re retrofitting an existing network, building a new distribution system, or integrating instrumentation, our Reduced Coupling ensures fast installation, leak-proof reliability, and long service life—maximizing uptime and reducing maintenance costs.
