1. Select the correct size

If your exhaust hose is not sized accurately you will run into temperature issues that can shorten the life of an exhaust hose.

When the I.D. is too small, friction from the large volume of vehicle exhaust will increase the temperature. When temperatures increase, pressure decreases. Excessive heat or can cause the hose to become brittle/hard, reduce flexibility, build-up static electricity, create discoloration, or result in cracks.

If the hose is not long enough, it loses the ability to contract and expand causing excess stress on the fittings or hose reinforcement.


Suitable I.D. sizes for general applications are:

2" - Small cars and motorcycles


4" - Large gas cars/ gas or light diesel trucks


2.5" - Average size cars


5" - Large gas or diesel trucks


3 and 3.5" - Average size gas cars/ light trucks


6" - Large diesel trucks




2. Conduct regular inspections

Frequently checking garage exhaust hoses for leaks, kinks, abrasions, and tears allows technicians to catch damages before hose failure and prevents the contaminated air that is being passed-through from entering the work area.


3. Store hoses properly

Garage exhaust hoses should be stored in a cool, dark place to prevent kinking, humidity damage, weathering, etc. Storing hoses near heat, in direct sunlight, or close to electrical equipment creates a high risk for damages.


4. Inspect exhaust hose components

Check fittings for signs of leaking, corrosion, or looseness, and replace them immediately to prevent hose failure or damage to the hose.


5. Understand the limits

Every exhaust hose has PSI, fluid compatibility, and temperature limits. If you exceed limits, overwork a hose, or pass incompatible fluids through, the results can range from tearing to bursting, deterioration, swelling or splitting, possible bodily damage, and slower work production rates.


6. Natural installation

During installation, allow garage exhaust hoses to naturally bend and twist.


7. Crushproof or wire reinforced?

Utilizing exhaust hoses that are made for your application will unmistakably lengthen the lifespan.

Wire-reinforced hoses are best for reel applications but because of their wire reinforcement should not be left on the floor. If they are stepped on or run over they will be crushed and no longer usable.

Crushproof exhaust hoses are ideal for floor applications because they can be continually run over and stepped on and will retain their shape.

Crushproof is not ideal for reel applications due to their flexibility which prevents them from holding their shape while on the reel.

WARNING: Vehicle Exhaust is extremely dangerous and potentially deadly. We always recommend that any system be properly engineered to meet the specifications of your application. If you are using our Crushproof system, we recommend that you use it with a fan and as an intermittent repair solution only, not to be run for long periods of time. This hose is to be used only with naturally aspirated 4 cycle engines running at an idle and under no load. We recommend keeping any run of hose as short as possible preferably 11' or under and sized to include ambient air to cool the exhaust temperatures. This hose is designed to handle frequent temperatures up to 400° and intermittent temperatures to 600°. When using Crushproof hose for the first time, watch closely to verify that the exhaust is exiting the building as designed. IF YOU SEE ANY EXHAUST COMING BACK INTO THE SPACE, THE HOSE IS NOT BEING USED PROPERLY. TURN THE VEHICLE OFF IMMEDIATELY AND CALL OUR EXPERTS.
