Buyers Guide on Plumbing Inverted Flare Brass Fittings

Plumbing inverted flare brass fittings are essential components in any plumbing system. These fittings play a crucial role in ensuring secure and leak-free connections between pipes, hoses, and other plumbing fixtures.

Inverted flare brass fittings are specifically designed to create reliable connections in plumbing systems. They are characterized by a flared end and a tapered nut, which, when tightened, creates a seal between the fitting and the mating component. Unlike compression fittings or tapered pipe threads, inverted flare fittings offer a unique sealing mechanism that provides enhanced leak resistance.

These fittings differ from other types of brass fittings, such as compression fittings or soldered fittings, by their specific design. The inverted flare design ensures a tight and secure connection, making them ideal for applications where maintaining pressure is critical. Inverted flare brass fittings are commonly used in automotive, gas, and hydraulic systems, as well as in household plumbing.

Types of Brass Inverted Flare Fittings We Offer

Inverted flare brass fittings come in a variety of sizes and configurations to suit different plumbing needs. In our store you can find various pipe fittings:

  • 45-Degree Elbow: This fitting features a 45-degree bend, allowing for a change in direction in your plumbing system. It is ideal for navigating tight spaces or creating angled connections without compromising the integrity of the plumbing line.

  • 90-Degree Elbow: Similar to the 45-degree elbow, the 90-degree elbow provides a sharper turn in the plumbing system. It is commonly used when a right-angle connection is needed, offering flexibility and versatility in routing pipes or hoses.

  • Hex Head: A hex head fitting incorporates a hexagonal shape on one end, providing a gripping surface for easy installation or removal using a wrench or socket. This type of fitting is convenient for applications where a secure and tight connection is required.

  • Nut: The nut is an essential component of an inverted flare fitting. It features internal threads that allow for tightening onto the mating component, ensuring a sealed connection. Nuts are available in various sizes to match the fitting and plumbing system requirements.

  • Plug: A plug is used to seal off or cap the end of a pipe or fitting. It provides tight closure and prevents the flow of fluids or gases. Plugs are commonly used when a temporary or permanent termination is needed in a plumbing system.

  • Straight/Connector: The straight or connector fitting is a simple, straight brass tube with flared ends. It allows for a direct connection between two pipes or fittings without any change in direction. Straight fittings are widely used to extend or join plumbing lines.

  • Tee: A tee fitting resembles the letter "T" and has three openings. It is used to create a branch connection in a plumbing system, splitting the flow of fluids or gases into two directions. Tees are commonly employed in residential and commercial plumbing applications.

  • Union: Unions are fittings that consist of three components: a nut, a male flare end, and a female flare end. They allow for the easy disconnection and reconnection of two sections of plumbing lines. Unions are useful when maintenance or repairs require the removal of a specific section of the plumbing system.

Advantages of Using Inverted Flare Brass Fittings

One of the key advantages of inverted flare brass fittings is the durability and corrosion resistance provided by the brass material. Brass is known for its strength and ability to withstand harsh conditions, making it a reliable choice for plumbing applications. The corrosion resistance of brass fittings ensures long-lasting performance and minimizes the risk of leaks or failures.

Another significant advantage of inverted flare brass fittings is their ability to create secure and leak-free connections. The design of the inverted flare, along with the tapered nut, ensures a tight seal when properly installed. This feature is especially crucial in applications where the integrity of the connection is critical, such as gas or hydraulic systems.

Inverted flare brass fittings are also known for their compatibility with various plumbing systems. Whether you are working with copper, brass, or even aluminum tubing, inverted flare fittings provide a versatile solution. Their compatibility extends to both residential and commercial plumbing systems, making them a reliable choice for a wide range of applications.

Factors to Consider When Choosing Inverted Flare Brass Fittings

When selecting inverted flare brass fittings for your plumbing needs, there are a few important factors to consider. First and foremost, it's essential to ensure that the fitting size matches the existing plumbing components. A mismatch in sizes can lead to leaks or improper connections. Take accurate measurements and consult the fitting sizing charts or manufacturer guidelines to determine the correct size for your specific application.

Quality and reliability are also crucial factors to consider when purchasing inverted flare brass fittings. Opt for fittings from reputable manufacturers or suppliers to ensure their durability and performance. Investing in high-quality fittings may initially cost more, but it can save you money and headaches in the long run by avoiding leaks or premature failures.

Cost-effectiveness and long-term value should also be taken into account. While it can be tempting to opt for cheaper alternatives, it's important to balance cost with quality. Cheap or substandard fittings may not provide the same level of reliability or durability as their higher-quality counterparts. Consider the long-term benefits and the overall value provided by the fittings when making your purchasing decision.

Installation and Maintenance Tips

Proper installation is crucial for the effective performance of inverted flare brass fittings. Follow these steps for a successful installation:

  1. Ensure that all components are clean and free from debris or contaminants.

  2. Apply an appropriate thread sealant or Teflon tape to the threads of the fitting.

  3. Insert the flared end of the fitting into the mating component.

  4. Hand-tighten the nut onto the fitting until it is snug.

  5. Use a wrench to tighten the nut an additional quarter turn to create a secure seal. Be careful not to overtighten and risk damaging the fitting or the mating component.

Regular maintenance is essential to prolong the lifespan of your inverted flare brass fittings. Inspect the fittings periodically for any signs of leaks or corrosion. If you notice any issues, promptly address them to prevent further damage. It's also recommended to follow manufacturer guidelines or consult a professional for specific maintenance recommendations.


Inverted flare brass fittings provide reliable and leak-free connections for various plumbing applications.
