AN Bulkhead Brackets -3AN & -4AN

AN Bulkhead Brackets -3AN & -4AN

Trying to cleanly plumb your Brake, Clutch, Vacuum, or Nitrous system?  These Brackets can help you do a clean and safe job!

These HRH AN Bulkhead Brackets are designed to accept any typical -3AN or -4AN* Bulkhead fitting and be mounted just about anywhere on your build.  This gives you an excellent way to solidly mount your Hard Line plumbing to your vehicle, and convert from Hard Line to Soft Line for flex joints.  A great way to mount Brake Lines coming down from your master cylinder to your frame rail. Can be used with Disc or Drum brake systems.

After years of disatisfaction with the available options for connecting Hard Lines to Flex Lines on Custom Car Builds, Alan Mandic, HotRodHippie, designed these brackets and has been using them ever since. 


Constructed of laser cut and press brake bent 5052 Aluminum. Each has 2 holes to accept -6AN Bulkhead fittings side by side for feed and return, or other uses. Has has 3 mounting holes sized for 1/4" or #10 sized bolts/screws. Can accept Bulkhead fittings of various angles. DESIGNED & MADE IN THE USA



These can be screwed to Sheetmetal, Bolted to Frame Rails, or Welded directly to any compatible aluminum components (fuel cell, etc).  Brackets can also be cut apart to be used as single hole brackets for solo lines.  Bracket width is designed to fit on a 3"(76.2mm) wide frame rail, Can also be mounted inside of a recessed C-channel frame rail on a classic muscle car or pickup truck.  Three mounting holes allow for mounting flexibility (2 bolts recommended per bracket.). Excellent for race car, restomod, classic car restoration, street rod, hot rod, or modern street car & truck builds. Great way to mount your Fuel Line Bulkhead Fittings, Air line fittings, or more!


May be able to be use for JIC Hydraulic Fittings as well.  Check your fitting dimensions to see if this could meet your needs for a JIC Hydraulic Fitting Mount.
