This 7-port vacuum tree is CNC machined out of T6061 billet aluminum and then anodized to harden and protect it from corrosion. Great to add in Boost Controllers, Gauges, Wastegates, and or any other component that require a separate vacuum source. Can also be used to replace the stock vacuum tree for a cleaner custom look.

Designed with 7 ports (two 1/4 NPT end ports, five 1/8 NPT ports) and also includes NPT plugs so you don't have to use vacuum caps if you don't have a use for all 7 connections. Can also be used for fuel or oil distribution. Be sure to use Teflon tape or paste on all NPT connections for a leak free seal. 

Hose Size Selection:
4mm Hose fits very snug on the 5 small ports, no clamps required for most applications.
6mm Hose fits tight enough to seal on a naturally aspirated application but would require clamps for boosted applications.
4mm and 6mm both fit on the smaller portsso if select which size will best fit whatever item you're connecting (boost controller, wastegate, etc.) as that's the deciding factor.
10mm Hose fits the larger ports on both ends that would typically connect to the intake manifold, brake booster, etc. Add thick wall hose option is presented three times to allow you to purchase each size at different lengths if desired.
