Wehrli 6.7L Cummins Thin Flange #10 JIC Male Fitting 2007-2018 Ram
This Wehrli coolant fitting delivers a secure press-fit connection for the coolant port behind the water pump on 2007-2018 Ram trucks with 6.7L Cummins diesel engines equipped with thin flange water pumps. It enables clean coolant rerouting in bypass kits or performance cooling setups while preventing leaks. The design ensures long-term durability under high-heat diesel conditions.
Key Features
- #10 JIC Male Thread: Standard AN/JIC sizing matches common coolant hoses and adapters for straightforward plumbing in Cummins cooling systems
- Thin Flange Design: Precision machined to fit the narrow coolant port profile on thin wall water pumps found on 2007-2018 6.7L Cummins
- Press-Fit Connection: Tool-free installation grips securely without threading into the aluminum housing to avoid cross-threading risks
- High-Temp O-Ring Seal: Viton material withstands 400°F+ diesel coolant temps for zero-leak performance over thousands of miles
- Mounting Bolt Tab: Integrated tab anchors the fitting during install and provides a tie-down point for hoses or brackets

- Small lightweight part ships in padded envelope or small box
