Description
Radium 6AN Male to 3/8" Spring Lock Female Fitting
Application: Spring-Lock coupler lines – Ford, Lincoln, Mercury and Panoz fuel lines confirmed by Radium (see Vehicle Fitment)
Part Type: 6AN male to 3/8in Spring-Lock female adapter fitting
Part Number: 14-0766
The Radium 14-0766 converts a 3/8in male Spring-Lock line to 6AN male, so an OEM Spring-Lock hard line can be connected to AN plumbing. Spring-Lock couplers are found in many vehicle hard lines, including Ford, GM, Chrysler, Toyota, Honda and Nissan.
Radium's Spring-Lock fittings are machined from 6061 aluminium and anodised for corrosion resistance. The integrated FKM O-rings make them compatible with petrol and alcohol fuels such as E85.
Key Features
- Spring-Lock Female: Accepts a 3/8in male Spring-Lock line
- AN Male: 6AN male flare connection
- 6061 Aluminium: Machined from 6061 aluminium and anodised for corrosion resistance

Important Notes
- To connect, lubricate the O-rings on the male fitting, push it into the female fitting until it clicks, then tug the connection to confirm it is locked
- A Spring-Lock disconnect tool is required to separate the fittings and is not listed as included. Slide the tool along the female fitting and push it into the male fitting, then hold it in place while the fittings are pulled apart
- Radium does not state which line size (3/8in or 1/2in) each vehicle uses – check your line size before ordering
