Product Details

The American Grease Stick BLF-172B is a brass brake line adapter designed to connect standard brake lines to different sized ports commonly found in dual master cylinders. This adapter features a male 3/8-24 inverted flare connection and a female M10x1.25 bubble flare connection, allowing secure integration between metric and SAE brake system components.

Key Features:

  • Brass construction for corrosion resistance and durability
  • Male side: 3/8-24 inverted flare thread
  • Female side: M10x1.25 bubble flare thread
  • Ideal for dual master cylinder installations and brake system conversions
  • Packaged in protective bag

This adapter fitting simplifies brake line connections by bridging different thread specifications. Simply match the male side of the adapter to the port connection on your dual master cylinder and connect the female side to your brake line. Essential for custom brake system builds, restorations, and master cylinder upgrades where thread sizes don't match.

Great deal on the tires I needed. Thank you. Shipping was SLOW but not your fault. Will be a return customer

So far so good

great price

Super easy transaction! Fast shipping!

Excellent! No problems at all

Representative Kori was extremely helpful over the phone , excellent employee, great customer service!!!

Easy to order!

Got the product fine, but it looks different than the part I was trying to replace. Only time will tell, once I try to install it, if it fits and will work.
