Uses of Brass Inverted Flare Fittings
 

Oil And Gas – These Brass Inverted Flare Fittings find application in processing equipment such as tanks, drilling rigs, and pumps, and used in the oil and gas industries giving stable performance in high stress and corrosive conditions.

 

Building and Construction – Scaffolding and other support structures requires variety Brass Inverted Flare Fittings to safeguard and guarantee the stability of structure during construction.

 

Chemical Refining – In chemical refineries, Brass Inverted Flare Fittings are made using corrosion resistant high performance materials, such as Brass, tool alloys, and exotic metals and find use in machineries such as heat exchangers, chemical tanks, and processing systems.

 

Marine – Brass Inverted Flare Fittings installed in the marine industry necessitate excellent corrosion resistance to withstand the extended periods of exposure to saltwater that marine ramps, marine decks, bulkheads, and tanks experience

 

Automobile And Transportation – Brass Inverted Flare Fittings are used to assemble a wide range of vehicles, including commercial vehicles like trucks, passenger vehicles like cars, airplanes, and specialized automobile equipment.

 

Power Generation – Distinctive applications include use in exhaust systems, electrical equipment, motors and pumps, and storage containers. These Brass Inverted Flare Fittings for the power generation industry are made of corrosion resistant and high strength materials such as Brass, aluminium, copper, nickel alloys, and other steel alloys.

 

Agriculture – In the agricultural industry, these Fittings are used in field irrigation and filtration systems, and other farming equipment, drying units, buildings, and grain bins.

 

Military – Military Brass Inverted Flare Fittings are manufactured and functionally designed to withstand extreme temperatures, corrosive compounds, and high stress environments and find applications like include equipment motors, heat exchangers, and engines, and processing equipment.

 

Measure Inverted Flare Fittings
 

Thread Size and Type

Use a caliper to measure the outside diameter (OD) of male threads or inside diameter (ID) of female threads.
Identify the thread type: Common types include NPT, SAE, and metric.

Flare Angle

Measure the conical flare angle where the tube meets the fitting, typically 37° (JIC) or 45° (SAE), using a protractor.

Tube Size

Measure the outer diameter (OD) of the tube to match the fitting size.

Fitting Type

Identify whether it's male or female, and the configuration (straight, elbow, etc.).

FAQ

 

Q: What is the difference between inverted flare and regular flare fittings?

A: Regular flare fittings have an external flare, while inverted flare fittings have an internal flare seat for better sealing.

Q: Can I use inverted flare fittings with any type of tubing?

A: No, they are designed for metal tubing such as copper, steel, and aluminum. Using plastic or rubber tubing requires adapters.

Q: How do I prevent leaks in inverted flare connections?

A: Ensure the flare is smooth and free of cracks.
Use proper torque settings to avoid under- or over-tightening.
Select compatible materials to prevent corrosion.

Q: Are these fittings reusable?

A: Yes, but only if they are in good condition. Replace if the flare is damaged or worn out.

Q: What are the standards for flare fittings?

A: The tool used to flare tubing consists of a die that grips the tube and a mandrel that is forced into the end of the tube to form the flare by cold working. The most common flare fitting standards in use today are the 45-degree SAE style, and the 37-degree AN style, also used with the JIC system.

Q: How tight should flare fittings be?

A: Thread the hose end or adapter nut onto the fitting until it cannot be tightened by hand any further. Lightly tighten the nut with a wrench (approximately 30 in. lbs.) making sure it does not bind; this is also known as tightening until wrench resistance.
