What is Phenolic?

Phenolic is a material used in the Aerospace and Electronic industry for its superior insulation properties. It has even been used by NASA during the space exploration as a heat barrier. Phenolic is made by compressing layers of resin soaked canvas while under heat. When cured, it has a brown grainy appearance which is commonly mistaken as “wood”.

Why we use it

We use Phenolic in our carb spacers and adapters to stop the transfer of heat from the engine to the fuel system. Intake manifolds and aluminum carb spacers readily transfer heat through the carburetor heating your fuel which has an adverse effect on performance. Our Phenolic spacers and adapters stops this transfer, therefor lowering the fuel temperature.

2bbl adapters and spacers

These spacers and adapters improve fuel mixture and provides a heat barrier to lower fuel temperature.

Four hole spacers

Four hole carb spacers increase the barrel lengths of your carb, which gives you improved low end response. These spacers should be used as a tuning aid. Results will vary depending on the cam, head, manifolds, and carb combinations.

Blended spacers

Our Blended Phenolic carb spacers provides a smoother transition from the individual carb barrels to the manifold giving you an improved fuel mixture.

Open spacers

The open carb spacers increase the plenum area under the carburetor. This increased plenum area improves the air/fuel distribution and has shown to be beneficial in high RPM applications. These spacers should be used as a tuning aid. The results will vary depending on the cam, head, manifolds, and carb combination.

Blended spacers

Our Blended Phenolic carb spacers for the Holley 4500 carburetor make a smooth transition from the round carburetor barrels into the square manifold base. This will improve the fuel charge.

Street applications

Street cars are exposed to extreme conditions where the underhood temperatures can rise to the point where performance begins to suffer. Phenolic insulators and spacers can help keep the heat from the engine away from the carb.

SBC fuel pump insulator

#85-000

#85-000 This SBC Phenolic fuel pump Insulator is made to take the place of the steel plate that is between the fuel pump and the block on the SBC. The insulator will limit the transfer of heat from the block into the fuel pump, therefor keeping the fuel passing through it cooler.

UNIVERSAL V8 fuel pump insulator

#85-010

#85-010 This universal Phenolic fuel pump insulator works with all domestic V8’s except Cleveland Fords and Oldsmobiles. The Phenolic material will limit the transfer of heat from the block into the fuel pump, therefor keeping the fuel passing through it cooler. It installs easily between the fuel pump and the mounting boss on mechanical fuel pumps.
