What it does
Thread type and size must match on both sides; AN, NPT and metric threads do not mix. 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.
- Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
