RX Venturi Barb

Why the RX Venturi Barb Delivers

Get stronger, more consistent vacuum where your dual-valve system needs it most — without cutting corners or reaching for specialty tools.

Redesigned for Higher Suction

The new Venturi design generates increased levels of suction at the secondary vacuum source, giving dual-valve systems the reliable vacuum reference they depend on.

Factory-Correct Angle and Placement

Engineered to install at the proper angle and orientation directly into the intake air tube or coupler, just upstream of the throttle body — so your vacuum reference port sits exactly where it needs to be.

Simple One-Evening Installation

All it takes is a 3/8" drill bit. Drill in at the correct angle, seal with RTV sealant on clean, oil-free surfaces, and let it cure overnight. No special equipment, no complicated procedures.

Clean, Concealed Mounting Option

Prefer a hidden look? The barb can be positioned underneath the intake tube or coupler to keep it out of sight — just confirm clearance from any belts or pulleys before committing to a mounting location.

Stop settling for a generic vacuum barb that wasn't built for the job — the RX Venturi Barb is the purpose-built solution your dual-valve system deserves.
