What is Minimum Bend Radius & Why Does It Matter?
The minimum bend radius is the smallest curve a hose can be bent without causing damage, kinking, or flow restriction. Bending a hose too tightly can lead to:
❌ Restricted Flow – Kinks reduce efficiency and increase pressure buildup.
❌ Structural Weakening – Excessive bending weakens the hose walls, leading to failure.
❌ Leaks & Ruptures – Over time, improper bending can cause hazardous failures.
Factors That Affect Minimum Bend Radius
🔹 Material Type – Rubber hoses are more flexible, while metal and thermoplastic hoses require larger bend radii.
🔹 Reinforcement Layers – Braided vs. spiral-wound reinforcements impact flexibility.
🔹 Temperature Conditions – Extreme heat softens hoses; extreme cold causes stiffness.
🔹 Pressure Rating – Higher-pressure hoses require a larger bend radius.
Best Practices for Proper Hose Installation
✔ Use the Largest Possible Bend Radius – Allow hoses to curve naturally.
✔ Avoid Sharp Bends Near Fittings – Maintain at least 18 inches of straight hose before bends.
✔ Use Hose Supports & Clamps – Prevent sagging and excessive bending.
✔ Factor in Temperature & Pressure – Select hoses designed for real-world conditions.
✔ Inspect Hoses Regularly – Look for signs of stress, leaks, or damage before failure occurs.
