Stainless Steel Flare Fittings Supplier

Stainless Steel Flare Pipe Fittings are designed and precision manufactured components and fitting parts used to connect, divert or close the pipe/tube ends in the process lines and instrumentation systems.

Features Stainless Steel Flare Fittings:

  • Zero-Leak Integrity: Generally, compression fittings or outlets are used for water and compressed air lines, where slight leakage isn’t going to cause too much of a problem. Flared fittings or outlets are used for gas and high-pressure lines, where even a little leakage can cause major problems if left unattended.
  • Metal-to-Metal Seal: Flared fittings type of joint consists of the main body and the nut, and connects the flare part of the pipe by crimping the main body and the nut part (seat surface).
  • Confined Space Installation: It is easy to install and remove even in narrow places, and it has better vibration resistance than the ferrule ring type and the compression type.
  • High Pressure & Refrigerant Service: Flared fittings find applications for high-pressure piping such as refrigerant and high pressure gas.
  • Extreme Conditions Durability: Stainless Steel Flare Fittings are precision designed to withstand high pressure, vibration, impact, vacuum and temperature changes.
  • Compact & Lightweight: Space-efficient design with exceptional mechanical strength.
  • Broad Tubing Compatibility: They can be used with 304, 316, or 316 L stainless steel tubing.
  • Safety Margins: Stainless Steel Flare Fittings has a 4:1 safety factor with respect to the working pressure capabilities of the tubing used.

Frequently Asked Questions about Stainless Steel Flare Fittings

Answers to the questions buyers, piping engineers, and procurement teams most often ask before sourcing Stainless Steel Flare Fittings from Pioneer Industries.

A Stainless Steel Flare Fitting is an ultra-reliable mechanical tube fitting engineered according to international standards such as SAE J514 (37° JIC flare) and SAE J513 (45° flare). It comprises a precision-machined fitting body with a flared nose (cone), a flanged sleeve, and a coupling nut. When tightened, the flared end of the stainless steel tube is clamped securely between the fitting body’s nose cone and the sleeve. This creates an impervious, high-integrity metal-to-metal seal that resists extreme pressures, vacuum levels, and thermal cycling without depending on elastomeric O-rings that can degrade.
The fundamental difference lies in tube preparation and mechanical holding method. Flare fittings require the tubing end to be expanded at a precise 37° or 45° flare angle prior to assembly, mechanically capturing the flared lip between the fitting cone and sleeve. This provides superior resistance to mechanical pull-out, severe hydraulic impulses, and persistent line vibration. In contrast, ferrule compression fittings swage (bite) into straight, unflared tubing. While ferrule fittings eliminate the need for a flaring tool, flare fittings remain the global standard in critical aerospace, defense, and high-pressure hydraulic circuits where catastrophic tube separation cannot be tolerated.
Pioneer Industries manufactures Stainless Steel Flare Fittings in fractional sizes from 1/8″ to 1″ outer diameter (OD) and metric tube sizes from 6 mm to 25 mm. They are engineered to interface with standard tubing wall thicknesses from 0.028″ to 0.120″ (0.7 mm to 3.0 mm). Connection thread profiles include UN/UNF straight threads for 37° JIC connections, NPT, BSPT (ISO 7/1 taper), and BSPP (ISO 228/1 parallel) pipe threads, as well as metric ISO threads for global equipment interoperability.
Depending on fitting geometry, size, and matching tube wall thickness, Pioneer Industries’ Stainless Steel Flare Fittings are rated for operating pressures ranging from 3,000 PSI up to 7,500+ PSI (200 to 500+ bar). All our flare fittings maintain a strict 4:1 safety design factor relative to tubing burst pressures under ambient and dynamic operating temperatures, adhering to ASME B31.3 process piping design codes.
Yes, exceptional reusability is one of the hallmarks of flare fittings. Because the sealing interface relies on mechanical compression of the flared tube against the precision-ground cone rather than cutting or indenting a sacrificial ferrule ring, the fitting can be disassembled for system maintenance, cleaning, or reconfiguration and retightened multiple times without compromising leak-tight performance. A brief visual inspection of the flare seat ensures continued integrity.
Our standard inventory is manufactured from premium ASTM A276 / ASTM A479 grade 304, 304L, 316, and 316L stainless steel bar stock and forgings. For highly aggressive offshore and chemical environments, we produce fittings in Super Duplex (2507), Monel 400, Inconel 625/825, and Hastelloy C276. We regularly supply material compliant with NACE MR0175 / ISO 15156 standards for sour gas upstream oil and gas service, featuring controlled hardness and heat treatment.
For optimal reliability: (1) Cut fully annealed stainless steel tubing (hardness ≤ 90 HRB) square using a sharp tube cutter; (2) Thoroughly deburr both inner and outer tube edges to prevent flare splitting; (3) Slide the flare nut and sleeve onto the tube facing the cut end; (4) Use a high-quality 37° orbital or hydraulic flaring tool to expand the tube to the exact diameter specified in SAE J514; (5) Align the flared tube squarely against the fitting nose and thread the nut by hand until finger-tight; (6) Tighten the nut with an open-end wrench to the specified torque or recommended flats from finger-tight (FFFT).
High-pressure gases, CNG/LPG, and modern synthetic refrigerants possess low molecular weight and high diffusivity, meaning even minuscule micro-voids in an elastomeric or biting ferrule seal can result in hazardous emissions or system depressurization. The precision coined metal-to-metal boundary created by a flared stainless steel joint provides a continuous, zero-leak metallurgical seal under thermal shock (-196°C cryogenic to +649°C elevated temperatures) and high-frequency fluid pulsation.
Every batch of Stainless Steel Flare Fittings undergoes rigorous quality control at our Mumbai testing facility, including 100% thread gauging, dimensional verification, hydrostatic pressure testing, and Positive Material Identification (PMI) spectroscopy. We provide full Material Test Certificates (MTC) compliant with EN 10204 Type 3.1 detailing chemical composition, tensile/yield strengths, and hardness with complete heat number traceability.
