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.

Nice product to clean up brake plumbing. Be SURE to use anti-seize prior to installation or test fitting, as threads may gall after one test fitting ! (mine did)
