3/8in Vac Fitting Push To Connect 90 Degree

The 3/8in Vac Fitting Push To Connect 90 Degree from REDHORSE PERFORMANCE is a precision air line adapter engineered for pneumatic systems, vacuum applications, and fluid transfer lines where space-saving 90-degree connections are essential. Designed for technicians, engine builders, and automotive enthusiasts, this fitting eliminates the need for multiple elbows and reduces system complexity in tight engine bays or custom fabrication projects. The push-to-connect design enables quick, tool-free assembly and disassembly without the need for wrenches or specialized coupling tools.

This adapter features a robust steel and plastic construction that combines durability with lightweight design, making it ideal for both street and competition applications. The 1/8 in NPT male inlet threads securely into manifolds, regulators, and valve ports, while the 3/8 in female quick disconnect outlet accepts standard push-connect hose couplers with a clean 90-degree angle. The integrated collet locking mechanism ensures a leak-free seal under pressure, preventing air loss and maintaining system efficiency across a wide temperature range common in automotive and industrial environments.

This fitting is ideal for custom fuel system builds, turbo plumbing, boost control lines, and vacuum distribution networks in performance vehicles. Installation requires only hand-tightening of the NPT port and straightforward insertion of quick-disconnect hose couplers—no additional adapters or reducers necessary. The compact 2.84 x 1.1 x 4.42 inch profile fits seamlessly into confined spaces, making it a go-to choice for engine bay layouts where standard 45-degree or straight fittings won't work.
