Full Description:
These adapter fittings are available in 5/16″, 3/8″, and 1/2″ sizes. They push-on and secure to most modern USA, European, Japanese, etc. fuel injection systems and are used to convert an OEM SAE Quick Connect connection.
The unique Radium Engineering adapter (20-0290 and 20-0291) interfaces with a SAE Quick Connect male fitting in an ultra-low profile manner. The design uses a dual viton O-ring seal for a leak free connection. The retaining clip is held on with a stainless steel screw and is easily and quickly serviced.
To determine the required SAE size, simply measure the outside diameter of the male fitting as shown in the photos.
• 0.3125 = 5/16″
• 0.375 = 3/8″
• 0.50 = 1/2″
Important Install Notes:
Always lubricate the mating O-rings with a light amount of oil prior to installing.
