### **Tools and Materials You Need**
– Replacement **O-rings** and **brass ferrules**
– **Hose splice kit** (barbed union)
– **Utility knife**, **heat gun**, and **wire brush**

### **Step 4: Fix Leaking Connectors**
If the leak is at the **brass fitting**, unscrew it and inspect the **O-ring**. Replace worn **O-rings** and wrap the threads with **Teflon tape**. Reattach and tighten with a **wrench**—but do not overtighten, as this cracks the **plastic collar**.
