20mm Full Flow Fittings

The 20mm Full-Flow Compression Fitting Series is a high-performance range of hydraulic connectors engineered for use with High-Density Polyethylene (HDPE) and Low-Density Polyethylene (LDPE) piping. These fittings are specifically designed to provide a “full-flow” internal diameter, minimizing friction loss and ensuring maximum volumetric water delivery in irrigation, agricultural, and domestic reticulation systems.

Mechanical Engineering and Internal Dynamics

• Full-Bore Geometry: Unlike standard fittings that can restrict the internal aperture, the 20mm full-flow design maintains a consistent internal diameter. This reduces turbulence and “head loss,” allowing pumps and gravity-fed systems to operate at peak hydraulic efficiency.
• Positive-Seal Compression Technology: The fitting utilizes a multi-component sealing system, typically consisting of a captive O-ring, a thrust washer, and a split-ring mechanical clincher (collet). As the nut is tightened, the clincher bites into the pipe wall, while the O-ring provides a high-pressure, watertight seal.
• Zero-Leakage Threaded Interface: Available in various configurations (couplings, elbows, tees, and threaded adaptors), the 20mm series is precision-tapped to ensure a deep, secure engagement with standard plumbing components and valves.
• Hand-Tighten Installation: Engineered for rapid field deployment, these fittings can often be installed and sealed by hand or with minimal tool assistance, significantly reducing labor time for large-scale irrigation layouts.

Material Integrity and Durability

• High-Impact Polypropylene Construction: Manufactured from UV-stabilized, high-grade polypropylene, these fittings are resistant to environmental stress cracking, corrosion, and chemical degradation from fertilizers and pesticides.
• Thermal and Pressure Stability: The reinforced body is designed to withstand the thermal expansion and contraction cycles common in outdoor African environments, maintaining a secure grip on the pipe even under fluctuating ground temperatures.
• PN16 Pressure Rating: Most professional-grade 20mm full-flow fittings are rated for pressures up to 16 bar (at 20°C), making them suitable for high-pressure mainlines as well as secondary lateral irrigation lines.

Operational Applications

• Agricultural Irrigation: Ideal for connecting 20mm HDPE pipes in orchards, vineyards, and vegetable gardens where consistent flow rates are critical for uniform crop hydration.
• Domestic Reticulation: Serves as a robust solution for garden hose connections, automated sprinkler manifolds, and outdoor tap extensions.
• Industrial Fluid Management: The chemical resistance of the polypropylene body makes these fittings suitable for temporary water bypass lines and low-concentration chemical transfer on work sites.

Designed for long-term reliability and hydraulic precision, the 20mm Full-Flow Fitting provides a dependable and high-efficiency connection for any modern piping network. Its robust construction ensures a maintenance-free lifespan, even in demanding agricultural and industrial soil conditions.
