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. If a hose is bent too tightly, it can lead to:
❌ Restricted Flow – Kinks reduce efficiency and increase pressure buildup.
❌ Structural Weakening – Excessive bending weakens the hose walls, leading to premature failure.
❌ Leaks & Ruptures – Over time, improper bending can lead to dangerous failures.
What Affects a Hose’s Minimum Bend Radius?
🔹 Material Type – Rubber hoses tend to be more flexible, while metal and thermoplastic hoses require larger bend radii.
🔹 Reinforcement Layers – Braided vs. spiral-wound reinforcements impact flexibility and strength.
🔹 Temperature Conditions – Extreme heat can soften hoses, while extreme cold can cause stiffness and cracking.
🔹 Pressure Rating – Higher pressure hoses are less flexible, requiring a larger bend radius.
Best Practices for Proper Hose Installation
✔ Use the Largest Possible Bend Radius – Give hoses room to curve naturally.
✔ Avoid Sharp Bends Near Fittings – Maintain at least 18 inches of straight hose before bends.
✔ Use Hose Supports & Clamps – Secure hoses to prevent sagging and excessive bending.
✔ Factor in Temperature & Pressure – Choose hoses designed for real-world operating conditions.
✔ Inspect Hoses Regularly – Look for signs of stress, leaks, or damage before failure occurs.
