-4AN 90 Degree Swivel Fitting

The AutoMeter -4AN 90 Degree Swivel Fitting is a precision adapter designed to redirect -4AN male connections at right angles, making it an essential component for pressure gauge installations and fuel system configurations where space constraints or routing requirements demand angled connections. This zinc-coated steel fitting delivers the reliability required in mechanical pressure gauge applications where accurate flow direction and secure sealing are non-negotiable.

Built from steel with a zinc coating for corrosion resistance, the fitting features a 4 AN female swivel connection on one end and a 4 AN male connection on the other, allowing flexible positioning of gauge lines without kinking or stress. The 90-degree angle eliminates the need for bulky bends in tubing and provides cleaner routing through tight engine bays or instrument panel spaces. The swivel design accommodates minor vibration and thermal expansion while maintaining a leak-free seal across repeated thermal cycles—critical for engine monitoring systems exposed to temperature fluctuations and pressure pulses common in high-performance applications.

This adapter is built for mechanics, engine builders, and hobbyists who need to install mechanical pressure gauges in confined spaces or unconventional mounting locations. Whether setting up an oil pressure gauge on a modified engine, routing a fuel pressure line in a race car fuel system, or adapting pressure transducers in diagnostic scenarios, this fitting provides a permanent, reliable solution that handles pressure cycles without degradation. The zinc coating offers baseline protection in most shop and engine bay environments, though regular inspection is recommended in salt air or highly corrosive conditions.

AutoMeter has established itself as a trusted manufacturer of analog gauges and gauge accessories for performance enthusiasts and professionals. -4AN fittings are an industry-standard specification in automotive performance and fuel system work, ensuring compatibility across gauges, fuel rails, and transmission cooler lines from multiple manufacturers. Stock this adapter as a critical spare for any shop or garage where gauge routing flexibility is essential.
