Great Product, However!

April 08, 2015
Actually the frame fittings are too long and if you cut them off the 1/8 NPT internal thread is not deep enough, and I purchase a brand new tap from MSC and another from ENCO and they both broke, so I decided to purchase a second set and just leave them the full lenght, which is not as custom. Have them made with 1/2 inch deeper internal thread!
Pros:
  • great if used full length
Cons:
  • not great if have to cut
Yes, I recommend this product.

The thru-frame fitting has AN 3 male threads on one end and 1/8" NPT female threads on the other. We offer part #91031831 to connect hard line. This is designed to use AN 3 lines to caliper.

Hello, Do you sell a 1/8 NPT 90 degree fitting with male and female end? I am looking to install the male end in the Thru-frame fitting on NPT side and the female portion of the 90, would accommodate the brake line itself? Thank you for your time

Typically a 90 degree fitting 91031833 is used to connect a 3/16" steel brake line with a 3/8"-24 inverted flare connection. Brake lines 91031800 will screw right into the female side of that adapter fitting.
