American Grease Stick BLF-34B Brass Brake Line Adapter Inverted to Bubble - 3/8-24 M13x1.5

The American Grease Stick BLF-34B is a precision brass brake line adapter designed to connect metric bubble flare ports to domestic inverted flare brake lines. This adapter features a female 3/8-24 inverted flare connection on one end and a male M13x1.5 bubble flare connection on the other, making it ideal for adapting metric master cylinder ports to 3/16-inch domestic brake lines.

Key Features:

• High-quality brass construction for durability and corrosion resistance
• Female side: 3/8-24 inverted flare (fits standard 3/16-inch domestic brake lines)
• Male side: M13x1.5 bubble flare (fits metric master cylinder ports)
• Essential for brake system conversions and upgrades
• Sold individually (1 adapter per bag)

This adapter is commonly used when installing dual master cylinders or performing brake system conversions where metric and domestic thread standards need to interface. Simply thread the male M13x1.5 side into the metric master cylinder port and connect your domestic brake line to the 3/8-24 inverted flare female side for a secure, leak-free connection.
