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.
These -3AN versions of our popular "Bulkhead Brackets" are able to be used with -4AN fittings as well. The design purposely has some extra material to allow you to drill out the -3 sized holes with a 7/16" drill bit to accept a -4 fitting. This can allow you to use these brackets with -3 AND -4 fittings for something like a Disc/Drum brake system or various other applications.
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 -3AN or -4AN* 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.
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 specifically designed to fit on a frame rail minimum 3"(76.2mm) or inside of the of the recessed portion of a classic muscle car or pickup truck C channel frame. 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 and truck builds.
Can accept Bulkhead fittings of various angles, though attention does need to be paid to interference between the two with anything other than straight fittings.
