Brass Flare Hardware

When compression joints leak due to misalignment or thermal expansion, it leads to downstream failures and added rework. Our Brass Flare Hardware supports SAE, JIC, and ISO flare standards to ensure lasting tube-to-fitting sealing across load conditions.

Component Type

Flare Nut, Flare Sleeve, Flare Union, 45° Flare Fitting

Tube Outer Diameter (OD) Compatibility

1/8″ – 3/4″ (3mm – 19mm)

Flare Angle

45° (SAE Standard), 37° (JIC Standard), Double Flare (Automotive)

Thread Size

#6-32 to 1-1/2″ (NPT/UNF) / M5 – M38 (Metric)

Thread Type

NPT, UNF, BSPP, Metric (Parallel)

Product Description

We offer nut, sleeve, and union sets that handle 300 to 3000 PSI based on flare angle and metal grade. Thread formats, nut lengths, and seal options can all be configured for specific equipment layouts.

Nut Length Type

Short (Standard), Long (High-Vibration), Adjustable (Custom)

Material Grade

C36000 (Free-Cutting Brass), CW617N (EN), C37700 (High-Strength)

Pressure Rating

300 PSI – 3000 PSI (20.7 – 207 bar) (Flare type-dependent)

Temperature Range

-65°F to 400°F (-54°C to 204°C) (Viton seals optional)

Hex Size / Wrench Flat Size

0.25″ – 1.25″ (e.g., 3/8″ flare nut: 9/16″ hex)

Internal Flow Diameter

0.1″ – 0.75″ (Matched to tube ID for optimal flow)

Compatible Flare Fitting Standard

SAE J512, ISO 8434, ANSI B1.20.1, DIN 2353

Finish/Coating

Natural Brass, Electroless Nickel (ENP), Chrome, Anti-Galvanic Coating

Standards Compliance

ASME B16.15, SAE J512, ISO 8434, NSF/ANSI 61 (Potable Water)

Weight

0.02 lb – 1.5 lb (Size/material-dependent)

Lead-Free Status

Compliant (RoHS, NSF/ANSI 61, WRAS)

Technical Advantages

Flare systems fail when seating surfaces deform or threads wear under repeated use. Our parts follow SAE J512, DIN 2353, and ISO 8434 standards for angle tolerance and thread accuracy. We offer both short and long-thread nuts, supporting vibration-critical environments where lock retention matters. Coating options include ENP and anti-galvanic finishes that reduce long-term maintenance across mixed-metal tubing.

Industry Applications

Refrigeration Compressors

Maintains vibration-proof sealing in copper refrigeration lines with 45° SAE nuts, used in chiller or HVAC skid assemblies.

Diesel Fuel Injection Systems

Fits metal fuel lines with 37° JIC flares, supports adjustable nut variants for pump-side alignment correction.

Off-Road Hydraulic Circuits

Delivers leak-free high-pressure performance in field machinery using double-flare sleeves and ENP-coated nuts.

Pneumatic Automation Lines

Prevents pressure drops in compressed air systems, with matched hex sizes to avoid over-torque during service.

Marine Propulsion Cooling

Resists galvanic failure in seawater lines using nickel-coated sleeves mated with metric brass flare nuts.

Water Filtration Assemblies

Handles NSF 61 potable water compliance while sealing PEX or stainless tubes in filter inlet and drain ports.

Sealing Across Tube Systems

Buyers often deal with incompatible flare types or tube wall tolerances during line design. We support hybrid setups with cross-standard angles and adjustable length nuts to simplify these builds.

Hardware is available in multiple grades like C36000 and CW617N to balance machinability and pull-out strength. Whether you require matched flare kits or just individual parts, we align output to your system conditions.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

Can you match flare hardware to both SAE and JIC tube ends in one assembly?

Yes, we support mixed-angle builds using custom flare nuts and sleeves for SAE 45° and JIC 37° standards. We control cone angle tolerances at ±0.5° to maintain sealing consistency. Assemblies ship matched to tube OD and thread format on request.

What thread formats can you offer for international projects?

We support NPT, UNF, BSPP, and metric parallel threads for both domestic and global builds. You can choose custom nut lengths to suit port depth or vibration conditions. All threads undergo go/no-go inspection before shipment.

Can I order parts in specific coating finishes like ENP or chrome?

Yes, we offer natural brass, electroless nickel, chrome, and anti-galvanic coatings based on application. Each part type can carry a different finish depending on contact material or exposure. We also support dual-coating setups for mixed-metal systems.

How soon can small batch orders be fulfilled for design validation?

We accommodate MOQ flexibility for development runs or equipment mockups. Based on part count and finish, lead time starts from 7 working days. Urgent batches can be scheduled with separate handling.

Do you offer flare nuts with vibration-locking features for dynamic loads?

Yes, long-thread and adjustable flare nuts are available for systems with thermal cycling or vibration stress. These help retain grip in mobile or high-pressure setups. We also offer fine-thread versions to reduce loosening risk over time.
