Are steel compression fittings safe for brake lines?

Compression fittings are used to join two pieces of brake line together. You cannot, under any circumstances, use compression fittings to repair the lines on a public transportation vehicle. Many states have banned the use of this repair on passenger vehicles, too.

What size compression fittings are there?

| How to Measure a Threaded Fitting

Tube Size Nominal Size No. of Threads per Inch
3/8″ 9/16″ 18″
1/2″ 3/4″ 16″
5/8″ 7/8″ 14″
3/4″ 1-1/16″ 12″

How much pressure can a compression fitting handle?

Compression fittings are the perfect choice for high pressure applications. In combination with a high pressure tubing material like steel, large compression fittings can often be used at pressures in excess of 10,000 psig.

Are compression fittings as good as solder?

Compression fittings are not nearly as robust as soldered fittings making them much more sensitive to powerful stresses. They are not ideal for applications where they could be potentially exposed to lots of flexing, bending and excessive vibration or tube movement.

Do compression fittings fail?

Unlike threaded fittings, compression fittings can seal properly but nevertheless slip out of position as a result of forces on a pipe. Analysis of the evidence suggests that the underlying cause of the failure was improper repair of a water pipe.

How are compression fittings used for steel tubing?

Compression Fittings for Steel Tubing Use these sleeves— also known as ferrules— with high-pressure compression nuts and fittings. They withstand about twice as much pressure as sleeves for standard compression fittings, so they’re good for hydraulic power applications.

How are compression nuts used in compression fittings?

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal. Use these sleeves with compression nuts and fittings, sometimes called bite fittings, to create a strong seal on steel tubing.

Which is the best thread for copper pipe fittings?

A 316 stainless steel body gives these fittings the best corrosion resistance of all our metal push-to-connect tube fittings. These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications. The threads on these fittings mate with NPT, NPTF, BSPT, and BSPP threads.
