We’ve heard your requests! Instead of stacking multiple adapters, we’ve created a simple one-piece fitting that goes directly from a 1/2×20 male thread to a -3AN male fitting. Just screw it into your Wilwood master cylinder and you’re done — quick and clean!

Made from corrosion-resistant 303 stainless steel for durability.

Need a 90-degree fitting in tight spaces? We also have a 1/2×20 to 1/8″ NPT female fitting, perfect for adding a B31890-11 elbow where space is limited.

These new fittings are designed for all Wilwood Master Cylinders with 1/2×20 threaded ports.
