Crushproof FAQ

How long are Crushproof hoses?

Crushproof hoses are manufactured in 11-foot lengths. However, the Crushproof ACT hose is available in 20-foot lengths and Crushproof reel hoses are made in 25-feet lengths as standard.

How do Flarelock hoses work?

Crushproof Flarelock hoses have one standard and one flared out end to allow multiple pieces to connect to one another without requiring additional parts.

What is the Crushproof temperature rating?

Crushproof hoses are rated to withstand intermittent temperatures of up to 600 degrees Fahrenheit.

What size exhaust hose and tailpipe adapter is recommended for my application?

View our exhaust hose chart and adapter application chart for application recommendations.

How do I choose the correct size hose?

We refer to the I.D. (inner diameter) of a hose. Tailpipes should always be around 1/2" smaller than an exhaust hose.

What happens if my exhaust hose is smaller than the tailpipe?

If your hose is not sized to be 1/2" larger than the tailpipe you will run into temperature issues that will reduce hose life.

If the I.D. is too small, the friction from high amounts of vehicle exhaust will increase temperature causing pressure to decrease which ultimately results in various hose damages.

What hoses accept multiple tailpipe adapters?

Most exhaust hoses will accept multiple tailpipe adapters and each adapter will fit on multiple hose sizes. For possible combinations, view the adapter application chart.

Are Crushproof hoses available with wire reinforcement?

We carry ACT Wire Reinforced hoses to prevent maximum crush protection and kinking prevention.

When is a Dyno exhaust hose required?

Dyno houses are recommended for use with a dynamometer because of its high heat rating. Dyno exhaust hoses must be attached to a fan assisted system to establish a long lifespan.

Do your adapters accommodate all vehicles?

Our tailpipe adapters are designed to fit most vehicles.
Keep in mind that there are a growing number of vehicles with dual or twin exhaust systems.
View the adapter application chart to ensure you select the correct adapters for your application or get in touch with one of our specialists.

How do adapters stay in place?

A hook and chain assembly is attached to each adapter allowing it to be fixed to the frame of the vehicle.

How do adapters attach to exhaust hoses?

Adapters will attach to hoses in one of these three ways:

1. Screw over the outside of the hose
2. Screw into the threads of the hose
3. The adapter will include sleeve screws into/onto the hose, then the adapter fits over/inside the sleeve.

What are Y-Connectors used for?

Y-Connectors are used to join hoses together to properly service dual exhaust vehicles.
Y-Connectors are sold individually in 2, 2 1/2, 3, and 4 inches or as a component of Y-Assemblies with hoses and adapters.

What are Splice Connectors used for?

Splice connectors join two sections of hose together when there is no Flarelock available.

How do Garage Exhaust Door Ports work?

Garage exhaust door ports allow a hose to fit inside of them when in use and are available in 2 1/2, 3, and 4 inches.

Do you offer larger door ports?

Because larger ports are generally installed with a custom system they are not available.
