Precision Tube Flaring & Swaging Capabilities

Our CNC-controlled flaring equipment delivers consistent, leak-free connections with support for SAE standards, custom geometries, and multi-stage operations.

Precision Flaring

CNC-controlled flaring dies create consistent flare angles (37°, 45°, 90° SAE standards) with ±0.1–0.2 mm dimensional accuracy for reliable sealing.

Swaging & Expanding

Hydraulic or CNC swaging expands tube OD or reduces ID for interference fits, barbed connections, and crimp sleeves.

Custom Geometries

Double flares, stepped swages, and complex multi-stage operations to meet application-specific connector requirements.

Flare Design & Manufacturing Process

Specification & DFM Review

Flaring and swaging performance depends on precise geometry, material properties, and connector interface. Our engineers review your specifications to recommend optimal tooling and parameters.

We provide design feedback on flare angles, clearances, and connector compatibility to ensure leak-free sealing and reliable assembly.

  • Tube material, OD (outside diameter), and wall thickness
  • Flare or swage type: angle, dimension, and position on tube
  • Multiple flares or swages: location and sequence
  • Connector interface specifications (SAE, ISO, or custom)
  • Surface finish and cleaning requirements
  • Quantity and delivery timeline

Flaring Workflow

  1. Tube Preparation — Clean ends, remove burrs, and precisely position in flaring vice
  2. Die Selection & Setup — CNC flaring machine loaded with correct die geometry (37°, 45°, 90°, or custom)
  3. Controlled Flaring — Hydraulic or servo press applies precise force to form flare angle and dimension
  4. Quality Verification — Flare angle, OD dimension, and bore checked; connector fit-test on sample parts

Common Flaring Applications

From aircraft hydraulic systems to automotive brake lines to HVAC refrigerant connections, tube flaring creates reliable, pressure-resistant seals across demanding industries.

Frequently Asked Questions

What flare standards do you support?
SAE 37° (JIC), SAE 45°, and SAE 90° flares. ISO flare specifications also available. Confirm your standard during quote process; custom angles possible for specialized applications.
What materials can be flared?
Steel, stainless steel, aluminum alloys, copper, and brass. Material hardness and wall thickness influence flaring parameters. Annealing available for work-hardened materials.
What is the tolerance for flare dimensional accuracy?
Standard tolerance ±0.1–0.2 mm for flare angle, OD, and length. Tighter tolerances achievable for critical applications; confirm during design review.
Can you perform multiple flares on a single tube?
Yes. Multiple flares (both ends or multiple diameters) completed in sequential operations. Complex multi-stage flaring requires engineering review.
What is swaging vs. flaring?
Flaring expands the tube end for connector seating; swaging reduces tube OD or ID for interference fits or attachment. Both can be combined in a single tube.
What is the typical lead time?
Samples typically 5–7 business days from approval. Standard custom tooling adds 3–5 days. Production runs can be expedited based on queue.
