Fittings

The right fittings are critical to building a reliable fluid or air system in any vehicle. Our Fittings collection brings together a wide selection of hose ends, adapters, and connectors designed for automotive plumbing. Whether you're plumbing fuel lines, routing an oil cooler, setting up a catch can, or building a custom air intake, you'll find the fittings to make leak-free connections.

When selecting fittings, consider these key factors:

  • Thread type: AN (JIC 37° flare) for high-flow racing applications, NPT for tapered pipe threads, or metric threads for OEM-style connections.
  • Material: Lightweight aluminum for weight-sensitive builds, corrosion-resistant stainless steel for harsh environments, or brass for durability and thermal stability.
  • Hose compatibility: Barbed fittings for push-on hose, push-lock for quick assembly, or reusable swivel-seal ends for braided hose.
  • Size: Match the dash size (-AN) or pipe size (NPT) to your hose and component ports for proper flow and fit.

Take the time to plan your system and choose fittings that maintain consistent I.D., meet pressure requirements, and avoid mixed thread types where possible. Our collection is built to help you get it right the first time.
