What it does
Quality hardware prevents leaks that are hard to chase down later. The right fitting, thread and size keeps a connection sealed and secure, which matters most on fuel, oil, coolant and brake lines.
Installation & tips
- Confirm thread type and size on both sides, and use the right sealant or none as the fitting type requires.
- Hose: Match hose size to the fitting.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
