Why Deburring is Essential:

• Prevents Leaks – Burrs can prevent proper sealing in flared connections
• Protects O-Rings – Sharp edges can damage O-rings and seals
• Improves Flow – Smooth edges reduce turbulence and pressure drop
• Professional Finish – Clean, deburred tubes indicate quality workmanship
• Prevents Contamination – Burrs can break off and contaminate the system

How to Use:

Inside Deburring

1. Insert pointed reamer end into tube
2. Rotate clockwise whilst applying light pressure
3. Continue until burrs are removed
4. Remove reamer and check inside edge

Outside Deburring

1. Place tube in V-shaped groove on reamer
2. Rotate reamer around outside of tube
3. Continue until burrs are removed
4. Check outside edge for smoothness

Maintenance:

• Keep blade sharp for best results
• Replace blade when dull or damaged
• Clean reamer after each use
• Store in dry location to prevent rust
• Inspect regularly for wear
