FAQ

What type of thread does this coupling use?

The Edelbrock coupling uses a standard NPT (National Pipe Thread) which is compatible with most fuel system components that require a secure, threaded connection.

Is the painted finish durable enough for high‑temperature environments?

Yes, the painted finish is formulated to resist heat and corrosion, making it suitable for high‑performance engines and racing applications.

Can this coupling be used with both gasoline and diesel fuel systems?

It is designed primarily for gasoline fuel systems, but it can be used with diesel applications provided the system pressure does not exceed the coupling’s rated limits.

What is the weight of the coupling?

The unit weighs approximately 0.704 ounces (0.02 kilograms), contributing minimal mass to the overall fuel system.

Is this part compatible with aftermarket performance manifolds?

Absolutely. The 6mm size and NPT threading make it a versatile fit for a wide range of aftermarket manifolds, fuel rails, and distribution blocks.
