Brass Straight Flare Tube Connector Fittings — Reliable Inline Connections for Fluid and Gas Lines

When a leaking or mismatched inline connection brings your plumbing, HVAC, or pneumatic project to a halt, having the right brass straight flare tube connector fitting on hand makes all the difference. Whether you're a professional tradesperson or a hands-on DIYer tackling a home repair, these fittings are designed to deliver a secure, leak-resistant metal-to-metal seal without the need for soldering or thread sealant tape.

Each fitting is machined from solid brass and features a straight-through body that connects two flare tube ends inline. Available in four outer diameter sizes — 1/8" (≈3.2mm), 1/4" (≈6.4mm), 3/8" (≈9.5mm), and 1/2" (≈12.7mm) — with body lengths of 6mm (≈1/4"), 8mm (≈5/16"), 10mm (≈3/8"), and 12mm (≈1/2"). Order in quantities of 1, 2, 5, or 10 pieces to match your project scope.

These brass straight connector fittings are well-suited for residential and light commercial plumbing repairs, HVAC refrigerant line connections, pneumatic air line assemblies, and fuel system maintenance — anywhere a dependable inline flare tube connection is required.

⚠️ Please verify your tube's outer diameter and confirm the fitting size matches your system before installation. If unsure, contact us to confirm compatibility.
🔵 Compatibility: Designed for standard SAE 45° flare tube systems. Generally compatible with copper and aluminum flare tubing in plumbing, HVAC, pneumatic, and light fuel line applications. Contact us to confirm for specialized systems.

✅ Key Features of These Brass Straight Flare Tube Connector Fittings

  • 🔩Solid Brass Construction — Machined from solid brass for durability, natural corrosion resistance, and long service life in plumbing and HVAC environments.
  • 💧Metal-to-Metal Flare Seal — The flare-type connection creates a tight, leak-resistant seal without thread sealant tape or soldering, reducing installation time and potential failure points.
  • 📐Wide Size Range — Available in 1/8", 1/4", 3/8", and 1/2" outer diameters with 6mm–12mm body lengths, covering the most common inline flare tube connector fitting sizes for residential and light commercial use.
  • 🔄Straight-Through Flow Path — The unobstructed inline design minimizes flow restriction, making these fittings suitable for fluid, gas, and pneumatic line connections where pressure drop matters.
  • 🛠️Tool-Friendly Installation — Compatible with standard flaring tools and wrenches; no specialized equipment required beyond what most plumbing and HVAC technicians already carry.
  • 📦Flexible Pack Quantities — Choose from 1, 2, 5, or 10-piece packs so you can order exactly what your repair or installation calls for, from a single replacement to a full project supply.

❓ Frequently Asked Questions

How do I choose the right size flare tube connector fitting?

Match the fitting's outer diameter to your existing tube's outer diameter: 1/8" (≈3.2mm), 1/4" (≈6.4mm), 3/8" (≈9.5mm), or 1/2" (≈12.7mm). Then select the body length — 6mm, 8mm, 10mm, or 12mm — based on the clearance available in your installation space. When in doubt, measure your existing fitting with calipers before ordering.

What pressure rating do these brass straight connector fittings typically handle?

Brass straight flare fittings generally handle working pressures in the range of 200–800 PSI depending on size and wall thickness. Smaller diameters typically support higher pressures. Please contact us to confirm the rated pressure for your specific size before use in high-pressure systems.

Can these fittings be used outdoors or in humid environments?

Brass offers good natural corrosion resistance and is generally suitable for indoor plumbing, HVAC, and moderately humid environments. For fully outdoor or marine applications, additional protection or stainless steel alternatives may be more appropriate. Contact us to confirm suitability for your specific environment.

What thread or connection standard do these fittings use?

These are flare-type straight connector fittings designed to connect two flare tube ends inline. They are generally compatible with standard SAE 45° flare tube systems. If you require NPT, BSP, or metric thread compatibility, please contact us to confirm before ordering.

How many pieces should I order for my project?

We offer 1, 2, 5, and 10-piece options. For a single repair or prototype, the 1 or 2-piece option works well. For installations with multiple connection points or to keep spares on hand, the 5 or 10-piece packs offer better value per unit.

Are these fittings compatible with copper, aluminum, or steel flare tubing?

Brass straight connector fittings are typically compatible with copper and aluminum flare tubing, which are the most common materials used with flare-type connections. Compatibility with steel tubing depends on the specific application and pressure requirements. We recommend verifying material compatibility for your system before installation.

Do I need any special tools to install these fittings?

Installation generally requires a flaring tool to prepare the tube ends and a wrench to tighten the fitting. No soldering or adhesives are needed. The flare connection creates a metal-to-metal seal when properly torqued, making it a straightforward process for most plumbing and HVAC technicians.
