Vibrant AN One Way Check Valve Piston Style

Vibrant Performance Piston Style One Way Check Valves (also called AN inline check valves or one-way fluid check valves) let fluid flow in one direction and block it from flowing back. They suit AN plumbing in oil, fuel, breather and other fluid systems.

Key Features:

• Piston-style design: A piston-type check mechanism gives dependable one-way flow control in AN-style plumbing.
• 6061 aluminum alloy construction: The valve body is made entirely from lightweight, durable 6061 aluminum alloy.
• AN flare fittings: The standard AN connections work with common AN hose and fitting setups.
• Universal application: The valves aren't tied to one vehicle. They can go into custom builds, racing setups and performance fluid systems.
• Lightweight and compact: The valves add little weight and take up little space in the engine bay or chassis.

Vibrant Performance is known for fabrication-grade fittings, hose and exhaust components. These check valves help protect pumps, lines and components by keeping fluid moving in the intended direction. Pick the AN size that matches your plumbing.
