Stainless Steel Bulkhead Unions are indispensable in industries where secure, leak-proof, and corrosion-resistant tubing connections are required through walls or panels. Available in multiple grades such as SS 304, SS 316, SS 321, SS 904L, and Duplex stainless steel, these fittings deliver exceptional reliability and versatility. Whether for hydraulic systems, chemical plants, or marine applications, stainless steel bulkhead unions remain a preferred choice for engineers and maintenance professionals worldwide.

Stainless Steel Bulkhead Union – Reliable Tube Fitting Solution for Industrial Applications

Stainless Steel Bulkhead Union is a precision-engineered tube fitting widely used in various industries where secure, leak-proof, and durable connections are required through panels, tanks, or bulkheads. Designed for high-pressure and high-temperature environments, these fittings offer outstanding performance in transferring gas, liquid, or hydraulic fluids across systems. With superior corrosion resistance, longevity, and compatibility with different piping systems, stainless steel bulkhead unions have become the go-to choice for industries demanding reliability and safety.

What is a Stainless Steel Bulkhead Union?

A bulkhead union is a specialized fitting that allows two sections of tubing to pass through a panel or wall while maintaining a sealed connection. Unlike standard unions, bulkhead unions feature a longer body and an additional lock nut, which ensures a firm attachment to the bulkhead. The stainless steel construction provides robust resistance against rust, chemical damage, and high-pressure fluctuations, making it suitable for demanding industrial operations.

Key Benefits of Stainless Steel Bulkhead Unions

  • Superior Corrosion Resistance – Stainless steel offers high resistance to rust, chemicals, and moisture, ensuring long-lasting service.
  • Leak-Proof Connections – Designed with precision threads and ferrules to prevent leaks even under extreme pressure.
  • High-Temperature Tolerance – Performs reliably in elevated temperature applications.
  • Durable and Maintenance-Free – With minimal wear and tear, stainless steel bulkhead unions reduce maintenance costs.
  • Versatile Application Range – Compatible with different types of tubing and adaptable for various industrial systems.

Applications of Stainless Steel Bulkhead Unions

These fittings are extensively used across industries where safe and durable tubing connections are crucial. Common applications include:

  • Petrochemical and Chemical Processing Plants
  • Hydraulic and Pneumatic Systems
  • Food and Beverage Industry
  • Pharmaceutical Manufacturing
  • Marine and Offshore Installations
  • Automotive and Aerospace Sectors
  • Power Generation and Water Treatment Plants

Available Materials and Grades

Stainless steel bulkhead unions are manufactured in various grades to meet diverse application needs. Common materials include:
