Check for Physical Damage
Inspect the silicone hose for cracks, tears, or punctures. Even small splits expand under pressure, leading to leaks. Look for bulges or soft spots—these signal internal weakening. If the silicone hose feels brittle and cracks when bent, it’s past its prime.
Watch for Degradation Signs
Notice discoloration (yellowing, fading, or dark spots) on the silicone hose. This means UV or heat damage. Feel for stickiness or a gummy texture; it indicates chemical breakdown from oils, solvents, or age. If the silicone hose loses flexibility and stays rigid, replacement is necessary.
Test for Leaks
Check connections around the silicone hose for wetness or fluid stains. Run the system briefly and watch for drips. Even tiny pinhole leaks worsen over time, so don’t ignore them. A leaking silicone hose can’t maintain proper pressure or flow.
Evaluate Age and Usage
If your silicone hose is 5+ years old, plan for replacement. High-heat, frequent vibration, or daily heavy use shorten lifespan. Even without visible damage, aged silicone hoses lose structural integrity.
Check for Fit and Function Issues
If the silicone hose kinks easily or won’t hold its shape, it’s compromised. Look for loose connections caused by a swollen or shrunk silicone hose. Poor fit leads to inefficient flow and demands replacement.
