LDHC Quick Clamp Coupling for Layflat Hose

The LDHC (Light-Duty High-Clamp) Quick Clamp Coupling is an engineered high-performance connection solution specifically designed for layflat hose systems requiring frequent assembly and disassembly. It solves the inefficiencies of traditional threaded connections, ensuring zero-leakage security under high pressure, vibration, and fluctuating flow conditions.

【Structural Composition】
The LDHC coupling consists of three key mechanical components engineered for reliability:

Clamp Body: Features a segmented (typically two or three-piece) clamping structure that uniformly wraps around the outer wall of the layflat hose.

This design allows the clamp to accommodate the hose‘s natural deformation under varying pressures, effectively preventing localized stress concentration.

Rapid Locking Mechanism: Equipped with an industrial-grade quick-release lever or anti-vibration bolts. Utilizing lever principle mechanics, it allows for rapid locking and release without specialized tools, significantly improving field operation efficiency.

Smooth Internal Bore: The interior features a fully step-free, smooth surface. This structural design ensures uniform pressure distribution and unobstructed fluid flow, substantially minimizing frictional resistance and head loss during fluid conveyance.

【Material Specifications】
LDHC couplings are manufactured using high-strength, corrosion-resistant materials to suit diverse and demanding environments:

Body Materials: Constructed from high-strength aluminum alloy or stainless steel. Aluminum alloy offers a balance of light weight and high strength, facilitating easy transport and handling. Stainless steel provides superior corrosion resistance, making it suitable for aggressive media such as seawater and chemical solutions.

Sealing Material: Equipped with a high-quality wear-resistant rubber sealing gasket. This gasket exhibits excellent elasticity and aging resistance, ensuring reliable sealing performance even under vibration and pressure surges.

【Applications】
The LDHC Quick Clamp Coupling is widely applied across the following sectors:

Agricultural Irrigation: Ideal for rapid connection of main and branch lines in sprinkler and drip irrigation systems, especially during temporary irrigation operations requiring frequent relocation of pumps and hoses.

Industrial Fluid Transfer: Widely used in mine dewatering, construction site drainage, and industrial wastewater transfer. In shale gas and oil fracturing operations, this quick coupling serves as a critical accessory for enhancing on-site efficiency.

Municipal & Emergency Response: Perfect for municipal firefighting remote water supply systems, flood control and emergency drainage, and temporary municipal sewage transfer applications requiring rapid hose deployment.

【Installation Guidelines】
Designed for maximum on-site convenience, the LDHC follows a simple four-step installation process:

Preparation: Cut the end of the layflat hose squarely and ensure it is free of burrs.

Insertion: Fully insert the hose end into the tailpiece or flange socket of the coupling, ensuring proper insertion depth.

Closure & Locking: Wrap the two or more segments of the clamp body around the hose, aligning the bolt holes or locking lever. Using a standard wrench (or manually engaging the lever), alternately tighten the nuts on both sides until the clamp uniformly grips the outer wall of the layflat hose. Thanks to its anti-vibration design, no periodic retightening is required after installation.
