🛠 The Engineering Advantage

Isolates Stress at the Panel: By securely anchoring the tube line to a panel, the bulkhead union isolates the internal connections from external forces, vibration, and accidental movement. This significantly enhances the long-term reliability of your entire hydraulic system.

Superior Strength with One-Piece Forging: Our monolithic forged body provides maximum resistance to installation torque and the high pressures characteristic of hydraulic systems, ensuring a robust and secure panel-mount connection.

Proven, Standardized Design: By adhering to the globally recognized DIN 2353 / ISO 8434-1 standard, our bulkhead unions guarantee dimensional interchangeability and performance you can trust for both new system builds and MRO replacements.

Molybdenum Disulfide Coated Nuts: To combat galling in high-torque hydraulic applications, all nuts are coated with Molybdenum Disulfide (Moly). This high-pressure solid lubricant ensures smooth assembly and allows for reliable reassembly.

📌 Targeted Application Support

Hydraulic Control Panels & Cabinets: The primary application for creating clean, secure entry and exit points for hydraulic tube lines.

Equipment Interfaces: Provides a fixed, robust connection point on the wall of a machine or process skid for external customer connections.

Vehicle & Marine Bulkheads: Ideal for safely routing hydraulic, fuel, or pneumatic lines through firewalls and structural bulkheads.

Test Benches: Creates organized and secure connection points for multiple lines on test and calibration panels.

❓ Frequently Asked Questions (FAQ)

Q1: What is the main purpose of a hydraulic bulkhead union?

Its main purpose is to provide a secure anchor point where a high-pressure tube line passes through a wall or panel. This protects the tubing from mechanical stress and vibration, simplifies system maintenance by creating a fixed disconnection point, and provides a clean, professional finish.

Q2: What information do I need to specify a bulkhead union?

You need to know three things: the tube O.D.(e.g., 12mm), the pressure series (L or S), and the maximum thickness of the panel it needs to pass through to ensure the body has sufficient length for the panel nut.

Q3: How does the single ferrule design perform in a bulkhead application?

It excels. The powerful "bite" of the hardened single ferrule provides exceptional resistance to the pull-out forces and vibration that can be transmitted through a panel, ensuring a leak-free seal on both sides.

Q4: Are your DIN 2353 bulkhead unions interchangeable with Parker EO®?

Yes, our fittings are manufactured to be dimensionally compliant with the DIN 2353 / ISO 8434-1 standard, making them interchangeable with other brands that also adhere to this standard, such as the Parker Ermeto (EO/EO-2) series. For critical applications, we always recommend using a consistent set of Stark components.
