Schedule 40 Pipe Fittings (Stainless Steel)Stainless Steel Schedule 40 Pipe Fittings - Long Radius 90 Degree

Schedule 40 Long Radius 90 Degree Butt Weld Pipe Fittings are available in A312 compliant dual certified 304/304L or 316/316L Stainless Steel with a mill finished inner and outer diameter (ID/OD). These stainless weld fittings conform to ASTM A403, ASTM A960, MSS SP-4, ASTM B16.9 (except wall), and MSS SP-43. Schedule 40 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.

Note: These will not work with our Stainless Steel tube and tube fittings that are sized by the outside diameter.
