Description
Overview:
The Brake Nuts Female 3/8 x 24 tpi are metal fittings used to secure brake lines to cylinders, hoses, and junctions in hydraulic braking systems. Each nut has a 3/8 inch (9.53 mm) UNF thread with 24 threads per inch and is designed for use on standard 3/16 inch (4.76 mm) brake pipe. Suitable for cars, vans, trailers, and many plant and garden machines that use UNF brake fittings, they help create a tight, leak-resistant seal when used with correctly flared pipe ends. The durable construction and corrosion-resistant finish make them suitable for use with copper, cupro-nickel, or steel brake pipe in everyday service and repair work. Sold individually, allowing you to replace only what you need for maintenance or custom brake line builds.
