[Update] Dot Approved Brake Line Compression Fittings

Dot Approved Brake Line Compression Fittings

During the use of traffic vehicles, your brakes will inevitably fail. Poor quality compression accessories will exacerbate this situation. Therefore, DOT-approved brake line compression fittings can be a better and safer choice for you.

So, how are DOT-approved compression fittings? Find out in our article below.

What are compression fittings?

It is a metal object, which connects one component of the coupling to another, usually some type of pipe, to create a waterproof seal. In particular, this accessory usually connects two parts of the brake line and prevents leakage. Compression assembly consists of a nut and a sleeve. When placed on the brake cord, the fitting makes a tight connection.

Your brakes make a significant difference in the safety of your ride. However, the use of compression fittings to patch a broken brake cord can be catastrophic. Many people choose this approach because it doesn’t have to be completely replaced and can save time.

Alternatively, replacing the brake cord can cost at least a few hundred dollars, which can put a strain on your budget.

What dangers can non-DOT-compliant compression fittings cause?

– There are three reasons for the dangers of using substandard compression:
– Poor quality compression fittings often melt at high temperatures
– They are also not made from the best steel and are loosely constructed.
– Poor quality compression accessories are prohibited from use in many states.

Unfortunately, the use of brake compression fittings causes many problems because your brakes put a considerable amount of pressure on the components. Besides, poor quality standards cause them to leak often when used on brake lines, causing brake fluid loss and ultimately brake system failure.

In most cases, you cannot use non-DOT-compliant compression fittings to repair lines on public transport. Many states have also banned this repair on passenger vehicles because of its potential danger.

However, this type of repair can be used for vehicles not traveling on public roads, highways, or high speeds. Lawnmowers or saws, for example, may accept unqualified brake-line compression fittings to cut production costs.

You can also use a compression accessory for temporary repairs. Specifically, in some vehicle maintenance situations, it is not necessary to use a standard compression accessory. Possibly, for example, might be you need to check the vehicle’s acceleration.

What are DOT approved brake line compression fittings?

Compression fittings should be properly designed, and both meet or exceed DOT requirements. It is important to confirm:

– Required PSI (pounds per square inch) pressure rating
– Specific subject type
– Type and material of the hose or hose to be compatible with the accessory

Main accessory specification:
– Brass fitting with stainless steel pipe support
– Compatible with SAE J844 Type A & B nylon hose
– Features and Benefits: Easy to install, no maintenance time, and minimizes the risk of leakage.
– Male pipe, female pipe, straight thread SAE
– Designated up to 250 PSI
– Meet SAE J2494 and DOT FMVSS 571.106 air brake specifications for sizes available from 1/4 ”to 1/2”.
– Stainless steel pipe support for maximum flow for SAE J3494-3


Brake line compression fittings work well in certain situations. If the vehicle is for off-road use or restoration, you can use substandard accessories for temporary repairs. In addition, public transport or expressway vehicles must use DOT-approved products.

Remember that while accessories offer an inexpensive alternative, they are not a long-term option. An accident will do much greater financial and ethical damage in the long run.
