Uses for Automotive Fittings

- Jan 11, 2019 -

Pipe Thread Fittings: These are dry seal fittings that use a tapered thread to create a strong, leak-proof bond. Pipe thread fittings can be found in various areas of an automobile such as the engine or console and may be kept in place using Teflon tape or other adhesives. Pipe thread automotive fittings are best suited for lower pressure systems.

Inverted Flare Fittings: The most common type of fitting in an automobile, inverted flare fittings have the capacity to withstand up to 5,000 psi of pressure. This is why inverted flare fittings are commonly found in the brakes and power steering systems. Inverted flare fittings require no additional sealer but provide a leak proof fit, making them a good fitting to use in the fuel and transmission systems. The strength of the inverted flare fitting comes from its uniquely designed double flare, which is folded back onto itself.

SAE 45-Degree Flare Fittings: An SAE 45-degree flare fitting is different than an inverted flare fitting because there is only a single flare. However, the SAE 45-degree flare fitting is still strong enough to be used in some of the instruments, the fuel line and hydraulic systems in an automobile. They are not recommended for the brakes however, as too much stress or pressure can cause them to crack.

Compression Fittings: Compression fittings are found throughout automobiles in low and medium pressure systems. Compression fittings use pressure to create a tight seal without the use of soldering or flaring. The result is an easily assembled fitting that is found in tubing, air lines and some hydraulic systems. Compression fittings are not strong enough to be used in the brakes or other high pressure systems.

Types of Automotive Fittings

There are a number of different materials that we may use when producing standard and custom automotive fittings including:

Brass – Brass fittings are affordable and commonly used due to their light weight and resistance to temperature changes. Brass fittings are often found in the cooling systems of an automobile because they can withstand extreme cold. Brass also corrodes slower than other materials, making it a long lasting metal for automotive fittings.

Plastic – While lightweight and inexpensive, plastic fittings are used for lower pressure systems like the windshield wipers or vacuum lines. Plastic or PVC is a durable and flexible material that will never rust or corrode. Plastic can become broken over time, but its low cost makes it easy to replace.

Steel – Steel automotive fittings are commonly found in many systems throughout an automobile. Steel alloys are also frequently used so that fittings can be lightweight but still strong enough to withstand high amounts of pressure. Steel automotive fittings are commonly found in the engine and break systems and are resistant to weathering and rusting.

Stainless Steel – Stainless steel is a steel alloy that is frequently used in automotive systems. Stainless steel is highly durable and can withstand strong pressure, making it a good material for any automotive hydraulic system. Stainless steel also lives up to its namesake by being highly resistant to rusting or corrosive damage, which allows automotive fittings to have a long life span.
