Brass Inverted Flare Fittings Supplier

Inverted Flare fittings are a type of compression fitting used with metal tubing. Tube flaring is considered to be a type of forging operation, and is usually a cold working procedure. During assembly, an Inverted Flare nut is used to secure the Inverted Flare tubing’s tapered end to the also tapered fitting, producing a pressure-resistant, leak-tight seal. Inverted Flared connections are often used in mission-critical and inaccessible locations as they offer high degree of long-term reliability. Inverted Flare fittings consist of a body with an Inverted Flared or coned internal cavity. Special flaring tools are used to install the tube to fit inside the Inverted Flared end, providing a deep seal. Inverted Flare fittings can handle higher pressures and a wider range of operating parameters than standard compression fittings.

From that point, apply a one-sixth turn. Please note, do not over-torque as this may damage the fitting or split the tubing at the Inverted Flare.

We at Pioneer Industries manufacture a wide variety of Brass Inverted Flare Fittings which finds applications in numerous industries like Oil & Gas Industries, Chemical Industry, Nuclear Energy Sector, Petroleum Industries, Defence Industry, and Aerospace Industry.

Frequently Asked Questions about Brass Inverted Flare Fittings

Answers to the technical questions automotive engineers, hydraulic technicians, and industrial procurement managers ask when specifying Brass Inverted Flare Fittings from Pioneer Industries.

A Brass Inverted Flare Fitting is a specialized mechanical tube fitting conforming to SAE J512 standards. In contrast to standard flare fittings (which feature external male body seats), an inverted flare fitting houses an internal female 42°/45° conical seat inside the fitting body. The tube is flared (typically double-flared) to match this cone. The male-threaded inverted flare nut slides over the tubing and threads directly into the female body cavity, forcing the flared tubing face securely against the internal seat. This creates an exceptionally compact, high-pressure, leak-free metal-to-metal seal protected from external impact and accidental thread damage.
Inverted flare fittings are the gold standard in automotive hydraulic brake lines, power steering circuits, and fuel delivery lines because of their superior vibration fatigue life, compact envelope, and high blow-out resistance. By enclosing the flared tube end completely inside the threaded fitting body, the flare is shielded from road grit, stone impingement, and corrosive de-icing chemicals. Furthermore, the threaded nut supports the tubing past the flare neck, dampening cyclical powertrain vibration that could otherwise cause fatigue cracking.
Pioneer Industries manufactures Brass Inverted Flare Fittings in strict conformance with SAE J512 (Automotive Tube Fittings), SAE J1231, and ASME B16.26. The nut ends utilize straight Unified National Fine (UNF / UNS) Class 2A male threads, while the fitting bodies feature precision tapped Class 2B female inverted seats. Port connections include standard NPT (ASME B1.20.1) and dryseal NPTF male/female pipe threads.
The fundamental difference lies in component orientation and envelope geometry. In standard flare fittings, the body has male threads and an exposed external cone, while the nut has female threads. In inverted flare fittings, the body has internal female threads and a recessed cone seat, while the nut has external male threads with a hex drive on the outside. This inverted design significantly reduces the overall fitting profile, saves critical clearance space in vehicle chassis and manifolds, and prevents overtightening distortion.
Double flaring folds the tube wall over on itself before forming the 45-degree sealing cone, effectively doubling the material thickness at the sealing radius. This is mandatory for seamless steel and copper-nickel (CuNi) hydraulic brake lines operating at 1,500 to 2,800 PSI, as single flaring on rigid or welded steel tubing is prone to longitudinal seam splits, edge burring, or wall thinning during wrench torque make-up.
Our Brass Inverted Flare Fittings are rated for operating pressures up to 2,800 PSI (approx. 193 bar) in 1/8″ to 3/8″ tube OD, and up to 1,500 to 2,000 PSI (approx. 103 to 138 bar) in 1/2″ and 5/8″ sizes, depending on tube alloy and wall gauge. The working temperature envelope extends from -54°C to +121°C (-65°F to +250°F), comfortably covering automotive engine bays, transmission cooling circuits, and industrial hydraulic systems.
Brass Inverted Flare Fittings are compatible with copper-nickel (Cupro-Nickel 90/10), soft annealed copper (ASTM B88), seamless brass, fully annealed aluminum, and low-carbon bundy-welded or seamless hydraulic steel tubing. The tube must be ductile enough to accept single or double 45° flaring without localized micro-fissuring.
Step-by-step assembly: (1) Cut tubing square and chamfer inside/outside edges; (2) Slide the inverted flare nut onto the tube with hex facing outwards; (3) Produce a clean 45° double flare using an automotive flaring tool; (4) Verify flare concentricity and OD with a micrometer; (5) Push the tube into the body until the flare rests flush against the internal seat; (6) Thread the male nut into the body by hand to prevent cross-threading; (7) While holding the tubing steady to prevent twist, tighten the nut with a flare nut (line) wrench until firm resistance is felt, then advance 1/6 turn (one flat) past finger-tight.
Yes, our high-purity brass alloys (CuZn39Pb3 / C36000 / C37700) are fully compatible with unleaded gasoline, E10/E85 ethanol blends, diesel fuel, biodiesel, engine oil, transmission fluid, and LP / propane gas. Because the joint relies strictly on metal-to-metal sealing with zero synthetic elastomers, there is no risk of seal degradation, swelling, or embrittlement caused by aggressive fuel additives.
Every shipment of Brass Inverted Flare Fittings from Pioneer Industries is backed by complete QA/QC documentation, including EN 10204 Type 3.1 Material Test Certificates (MTCs), optical profile verification of internal seat angles, thread pitch gauge verification, 100% pneumatic bubble leak testing, and proof hydrostatic pressure testing. Heat numbers are logged for end-to-end raw material traceability.
