Schedule 40 ss fittings are Nominal Pipe Size (NPS), not Tube Outside Diameter (OD). The walls of Schedule 40 pipe and fittings are almost twice as thick as standard 16 gauge Tube OD fittings, making them ideal for custom turbo manifolds and downpipe fabrication. The increased wall thickness provides added durability and is less prone to cracking under the high thermal stress from exhaust gas temperatures.Additional buttweld pipe fittings are available in long radius 45's, short and long radius 90's, tee's and straight lengths for making anything from log style manifolds to equal length twin scroll manifolds. Great for use in conjunction with Vibrant Turbo Manifold Merge Collectors and 1/2" Thick Mild Steel Manifold Flanges which are optimized for Sch. 40 fittings.
