Stainless Steel Flareless Elbow Unions – Marine-Grade Pipe Fittings

Our stainless steel flareless elbow unions are precision-engineered for marine and industrial piping systems. Designed with a 90° elbow configuration, these fittings allow safe and efficient directional changes in hydraulic, pneumatic, and instrumentation lines while eliminating the need for tube flaring. Constructed from high-grade 316L stainless steel, they offer exceptional resistance to corrosion, pitting, and seawater attack, making them ideal for shipboard applications.

The union design provides easy installation and maintenance, enabling quick disconnection and reconnection of pipe lines without disturbing the overall system layout. Each fitting is manufactured to tight tolerances and undergoes rigorous quality checks to ensure a leak-free connection under extreme pressures and vibrations. Available in a range of inch and metric tube sizes with various thread types, these flareless elbow unions are a reliable choice for deck machinery, engine room piping, and offshore equipment.

Whether you are refitting a vessel or building new marine systems, our flareless elbow unions deliver long service life and dependable performance. Their compact design saves space, while the robust construction meets the demanding requirements of Class societies and international standards.

Frequently Asked Questions

What is a flareless elbow union?

A flareless elbow union is a type of pipe fitting that connects two tubes at a 90° angle using a compression ferrule system, eliminating the need to flare the tube ends. It is commonly used in high-pressure hydraulic and marine piping systems.

Are these fittings suitable for seawater applications?

Yes, our stainless steel flareless elbow unions are made from 316L stainless steel, which offers excellent resistance to chloride-induced corrosion, making them well-suited for seawater exposure in marine environments.

What tube sizes and thread types are available?

These fittings are available for tube sizes from 6 mm to 38 mm (1/4" to 1-1/2") and can be supplied with NPT, BSPT, or metric threads to meet a variety of marine piping requirements.

Do I need special tools to install flareless fittings?

Installation is simple and typically requires only standard wrenches. The bite-type ferrule grips the tube securely without flaring, reducing labor time and minimizing the risk of leakage.
