SMX Exhaust Turbo Flange for Yanmar 6LYA 370/440

These are the finest quality exhaust flanges you can get————-Investment cast SS316L and machined to +/- .001”.. Extra heavy duty “weld boss” section to 100% prevent warping when welding. Designed to use with or without a gasket (we prefer a coat of high temp silicone on the mating surfaces to the turbo and anti-seize on the Marmon/V-band clamp bolt). 1/8” or 1/4” NPT Pyro Probe / Test Port is optional—You will need to specify.
