715-Q6-06 – 3/8" EFI Quick Connect to -6AN Male

The Speedflow 3/8" EFI Quick Connect to -6AN Male Adapter has been designed to make connecting and disconnecting OEM EFI fuel systems faster, easier and more secure.

Unlike conventional OEM quick-connect fittings that rely on retaining clips or C-clips, the Speedflow design features an innovative push-on locking system. Simply push the fitting onto the OEM 3/8" EFI tube until the collar clicks into place, then rotate the Safety Lock Collar to engage the secondary lock, preventing accidental disconnection.

When servicing is required, rotate the Safety Lock Collar until the Release Tab aligns with the body groove. Pull the collar rearward and the fitting releases effortlessly—no clips, C-nuts or special disconnect tools required.

Designed, engineered and manufactured entirely by Speedflow in Taree, NSW, Australia, every fitting is precision CNC machined from premium 6061-T6 aluminium and incorporates stainless steel locking balls, custom-designed springs and Viton® O-rings for reliable performance with modern fuels.

Finished in Speedflow's signature black and gold anodising, the 715-Q6-06 delivers a premium appearance with the durability expected in high-performance fuel systems.

Whether you're upgrading an OEM fuel system, building a race car or fabricating a custom EFI installation, this fitting provides a professional, reusable connection that makes future servicing simple.
