Where can I buy hose clamps like the black ones on the pic?

 

Those aren't hose clamps, they are AN fittings . You can get them from any performance shop but most popular would be JEGS.com, anplumbing.com, pitstopusa.com, anfittingsdirect.com etc... Google.

 

summitracing.com has a good selection of those hose ends (and other AN fittings) from manufacturers like Earl's, Aeroquip, and their own private label stuff. The good thing about ordering from summit is you can return unused items.

 

Yeah, they are actually Hose Clamp Covers & not AN fittings.
Pretty obvious really.
Most speed shops carry them, or Ebay, Aluminium HEX Clamp Finisher Hose END FOR Braided Hose Black AN 12 | eBay

 

They are hose clamp covers. Had these on my MINI BSH oil catch can. Ended up with a different design, but I only have pics of the first setup. Same concept though. (I ordered both through Jegs)

 

Thanks everyone! i will look them all up!
