Brass Flare Connectors & Unions

If threaded joints leak or loosen under vibration, system downtime and fluid loss can increase. Our Brass Flare Connectors & Unions reduce these risks by offering form types like elbows, tees, and bulkhead flares, all with metal-to-metal sealing.

Connector Type/Form

Straight Union, 45° Elbow, 90° Elbow, Tee, Bulkhead Flare

Tube Outer Diameter (OD) Compatibility

1/8″ – 3/4″ (3mm – 19mm)

Flare Angle

45° (SAE Standard), 37° (JIC Standard)

Threaded Connection Size

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

Threaded Connection Type

NPT, BSPP, UNF, Metric (Parallel)

Product Description

These connectors support both SAE 45° and JIC 37° flare angles across male, female, and union threads. With options in C36000 and CW617N brass grades, we match both pressure demand and fitting style with dimensional consistency.

Threaded Connection Gender

Male (M), Female (F), MxF (Union)

Number of Flare Ends

Single Flare, Double Flare (both ends flared)

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)

Overall Dimensions

Straight – 0.75″–3″ / Elbow – 1″–2.5″ (center-to-end) / Tee – 1.5″–4″

Hex Sizes

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

Internal Flow Diameter

0.1″–0.7″ (Smooth bore for minimal restriction)

Compatible Tubing Material(s)

Copper, Aluminum, Nylon (reinforced), Stainless Steel

Finish/Coating

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

Standards Compliance

SAE J512, ISO 8434, ANSI B1.20.1, NSF/ANSI 61, DIN 2353

Technical Advantages

Systems with mixed thread types and flare angles need exact control over angle geometry and depth fit. We support full interchangeability between NPT, UNF, BSPP, and metric formats, machining both male and female types in the same lot. Elbows and tees follow standard bend radii and consistent center-to-end lengths for easy installation in tight setups. Coatings like ENP or anti-corrosive layers extend product life under chemicals or outdoor exposure.

Industry Applications

HVAC Refrigerant Lines

Used in 45° SAE flare setups for copper tube joints in AC and chiller lines.

Hydraulic Equipment

Supports 37° JIC flare ends for compact hydraulic flow paths with low restriction.

Compressed Air Systems

Used with aluminum or nylon tubing to reduce threaded leakage risks in low-pressure air circuits.

Automotive Braking Circuits

Double-flare unions maintain vibration resistance in steel brake line assemblies.

Food-Grade Fluid Transfer

Chrome-finished bulkhead connectors connect stainless steel pipes in non-reactive processing lines.

Instrumentation Systems

Enables leak-free tee and elbow connections in copper or SS tubing for flow meters or sensors.

Built for Complex Tube Assemblies

Tube layouts with frequent junctions or changes in direction often face leakage from fitting misalignment. Our flare connectors manage thread engagement and cone angle precision across a wide range of tube OD sizes.

Designers gain freedom to route complex pipe runs using elbows, tees, or bulkhead forms without risk of seal failure. We support project-specific quantities and mixed-format kits to suit your end-assembly requirements.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

Can we request mixed thread types or flare angles in the same connector order?

Yes, we support combinations like NPT to UNF or 37° JIC on one end and 45° SAE on the other. This helps in setups where your equipment or tubing varies across assemblies. You can specify flare angle and thread types per part number or connection end.

What connector forms are possible for compact or angled installations?

We manufacture 45° and 90° elbows, tees, and straight types with optional bulkhead styles. Center-to-end lengths and hex sizes are adjustable within standard tolerances. This allows tight routing without bending the tubing or using multiple fittings.

Is there a minimum quantity for bulkhead or special elbow fittings?

We handle custom form types or uncommon thread sizes from as low as 250 pieces. Lead times vary based on machining setup, usually 2 to 4 weeks for such batches. You can mix male, female, and union types in one lot if threads remain consistent.

How do you control sealing fit across flare and thread ends?

We control cone angle, seat depth, and thread engagement using CNC-calibrated dies and GO/NO-GO gauges. Each batch is matched to compatible tubing OD and seat finish to prevent misfit. You can also request bore smoothing or ID match to reduce flow turbulence.

Will the finish hold up in outdoor or chemical contact applications?

We offer Electroless Nickel, Chrome, and anti-corrosive coatings for higher environmental resistance. You can choose finish based on exposure, brass for indoor, ENP for corrosive, and chrome for visual appeal. We match coating thickness with connection threads to avoid galling or slippage during tightening.
