2017-2026 Duramax L5P Billet Turbo Coolant Fitting With O-ring Seal

These Square Root Fab fittings are machined out of billet aluminum to replace the factory line that’s prone to cracking and leaking! Another benefit to this fitting, it utilizes a high temp o-ring to ensure a tight seal so you don’t have to reuse the factory style gasket. These are designed for offroad application L5P's.

We also sell the silicone cap that is relevant to this fitting. Found HERE
