When upgrading your engine bay or fuel system, it can be difficult to know exactly what type of hose you need. With so many hoses on the market, you may run into problems selecting the correct material hose for your desired application. This piece is designed to help you understand the difference between PTFE and Nitrile rubber hoses, so that you can choose the correct one for you.

As with everything, PTFE and Nitrile rubber hoses both have their advantages and disadvantages. Understanding them is important, as it could make a big difference to your fuel system.

Nitrile rubber braided hoses offer great resistance to oil and fuel. The flexible rubber means that nitrile rubber hoses offer an excellent bend radius. This means that you can create the desired system without the need for extra fittings and angles. The hoses can be bent and fixed as needed, resulting in a sleek and tidy fuel system.

However, nitrile rubber hoses should never be run inside the cabin as fuel fumes can permeate through the wall of the hose. They should only be run in areas such as underneath the car, or under the hood.

For hoses that need to be run inside the cabin, PTFE hoses are ideal, as fuel fumes will not permeate the hose walls. However, as PTFE hoses have a significantly reduced bend radius, more angle and end fittings may be required, which increases the chance of a leak occurring in the system. While PTFE hoses are generally cheaper, the savings are often spent on the extra fittings that are required. An additional benefit however is that PTFE hoses are lightweight, so if weight is a concern, PTFE hoses might be the ideal solution for your fuel line.
