Radium Thermal Spacers and Vacuum Port Adapters | Universal (14-0715 / 14-0720 / 14-0727 / 14-0769 / 14-0190 / 18-0112)

Small parts that keep heat out of the fuel and vacuum where it belongs.

Two groups of service parts here: thermal insulating spacers that isolate fuel rails from cylinder head heat, and vacuum port adapters for Radium fuel pressure regulators and pulse dampers.

Choose Your Part

• Insulating spacer 15mm (14-0715)
• Insulating spacer 20mm (14-0720)
• Insulating spacer 27mm (14-0727)
• 1/4in push-to-connect vacuum port adapter (14-0769)
• 3/16in barb fitting (14-0190)
• Vacuum port plug (18-0112)

Features

• Press-in thermal insulating spacers in three heights
• Vacuum port fittings in push-to-connect and barb styles
• Vacuum port plug for constant-pressure setups

The Details

Insulating spacers sit between the rail and the head, reducing heat soak into the fuel. They are supplied with several Radium rails, so these are replacements or extras; match the height to the rail you are working with.

On the vacuum side, the choice is about how you are plumbing the reference line. The 14-0769 takes 1/4in tubing on a push-to-connect, the 14-0190 is a 3/16in barb for hose, and the 18-0112 plugs the port entirely, which is what you want when running a regulator at constant pressure with no manifold reference.

Applications

• Radium fuel rails using thermal insulating spacers
• Radium fuel pressure regulators and fuel pulse dampers with 10-32 vacuum ports

Important Notes

• Sold individually
• Match spacer height to your fuel rail application
