904557 Oil line fitting, straight. 1/8 NPT to 5/16". chrome

This straight oil line fitting is a versatile piece of hardware for any custom oil system or repair. It features a 1/8 NPT threaded end that tapers into a 5/16" (7.9mm) hose barb, making it compatible with standard 5/16" inside diameter oil lines. Finished in high-quality chrome, it looks great on external oil tanks or filter housings. This is a universal fitment part, meaning it can be used on almost any Harley-Davidson or custom build where a 1/8 NPT port is present. Whether you are plumbing a custom oil cooler or replacing a corroded factory fitting, this MCS component provides a leak-free connection and a clean, professional appearance for your motorcycle's plumbing.
