Flare Bulkhead Unions are widely used in hydraulic and pneumatic systems, fuel and gas lines, and instrumentation tubing where connections must pass through panels or walls. Common industries include oil and gas, chemical processing, marine, aerospace, and industrial manufacturing. These fittings help organize piping layouts, improve system safety, and prevent leakage at transition points. Their robust design and secure sealing make them ideal for both high-pressure and critical service applications.
