Flare Fittings

Precision Flare Tube Fittings

Deep Enterprise manufactures precision flare fittings engineered for robust, leak-tight tube connections in dynamic hydraulic and pneumatic environments. Designed for single and double flare configurations, each fitting is produced to achieve accurate seating angles and consistent clamping forces on metal tubing.

These fittings are ideal where vibration resistance, repeatable assembly, and serviceability are critical—such as fuel lines, brake circuits, refrigeration loops, and instrumentation panels. Controlled machining, uniform thread quality, and carefully finished sealing surfaces ensure dependable performance over prolonged operating cycles.

Flare Fittings

Applications

Our flare fittings are chosen wherever secure, serviceable tube connections are required:

Fluid & Fuel Lines

Connections for fuel, oil, and hydraulic lines in automotive and off-highway equipment.

Refrigeration & Instrumentation

Tube joints in refrigeration circuits, gauges, and control panels handling gas or liquid media.

Key Features
