Oil Drain Flange 5/8in OD Male Neck

The Oil Drain Flange 5/8in OD Male Neck by Vibrant Performance is an essential component for custom oil system installations and engine modifications. Designed for builders and enthusiasts who need precise control over oil routing and drain configurations, this flange serves as a critical junction point in high-performance cooling and filtration setups. Whether you're fabricating a custom dry-sump system, upgrading to remote oil filtration, or integrating modern oil management on a classic engine swap, this adapter provides the secure connection point your build demands.

Engineered with precision manufacturing, the 5/8-inch outer diameter male neck accepts standard hose connections while the flange body seats against engine block ports or custom manifold adapters. Vibrant Performance's reputation for durability ensures this flange handles sustained oil flow and temperature cycling without degradation—critical for applications running elevated engine temperatures or high-volume cooling systems. The compact footprint (2 x 1.5 x 2.5 inches) makes it ideal for space-constrained engine bays where traditional oil pan drain systems create packaging conflicts.

This drain flange is indispensable for fabricators working on LS engine swaps, turbocharged builds requiring custom oil supply lines, or track-focused vehicles with remote cooler installations. Installation requires matching the flange bore to your block or manifold design, then securing with appropriate fasteners—a straightforward process for experienced builders. Compatible with any standard 5/8-inch ID hose and clamp system, it integrates seamlessly into both street and competition applications where reliability and clean engineering matter.
