1/4in Vac Fitting Push To Connect 1/4in NPT

The 1/4in Vac Fitting Push To Connect 1/4in NPT from REDHORSE PERFORMANCE is a precision vacuum line connector engineered for modern automotive fuel systems, emissions control, and boost control applications. Whether you're tuning a high-performance engine, installing a custom fuel pressure regulator, or integrating a turbo boost controller, this push-to-connect fitting eliminates the guesswork of traditional barbed connectors and provides a leak-free seal every time. Mechanics and enthusiasts rely on REDHORSE fittings for their reputation in maintaining system integrity under demanding conditions.

This fitting combines a 1/4-inch push-to-connect interface with a 1/4-inch NPT (National Pipe Thread) male port, allowing seamless integration into vacuum distribution blocks, manifolds, and hard-line tubing systems common in fuel injection and turbocharger plumbing. The push-to-connect design uses a collet-lock mechanism that grips silicone and rubber vacuum lines without barbs, reducing insertion force while preventing hose blowoff under high-vacuum cycling and temperature fluctuations. The NPT port accepts standard adapter fittings, elbows, and T-blocks, making this connector ideal for custom routing in engine bays where space is tight and hose paths are complex.

Builders working on EFI conversions, standalone engine management systems, and aftermarket turbo installations will find this fitting indispensable for vacuum signal plumbing and emissions bypass circuits. Its compact 2.84 x 1.1 x 4.42-inch profile fits into tight radiator support bays and custom manifold clusters without interference. Installation is straightforward: insert the vacuum hose into the push-to-connect port until it seats, then lock it down by rotating the outer collar—no tools required. For reliability in street machines, drag cars, and road-racing platforms, REDHORSE Performance fittings are the standard choice among professional engine builders.
