Overview
The SV Series Single Ferrule Hydraulic Bulkhead Union connects two metric tubes of the same outside diameter through a panel, enclosure or equipment wall.
Both tube ends use the 24° cutting-ring connection system, while the bulkhead body is secured through the mounting surface to provide a fixed straight-line tube connection.
L and S series are available for different metric tube sizes and hydraulic system requirements.

Select the required tube series and tube O.D. according to the hydraulic system and installation requirements.
Working Pressure
Working pressure varies according to the selected tube series and tube O.D.
Series / Tube O.D. | Working Pressure |
|---|---|
L: 6–18 mm | 315 bar / 4560 psi |
L: 22–42 mm | 160 bar / 2320 psi |
S: 6–14 mm | 630 bar / 9130 psi |
S: 16–30 mm | 400 bar / 5800 psi |
S: 38 mm | 315 bar / 4560 psi |
Pressure ratings should be considered together with the tube specification, tube material, wall thickness, operating temperature and complete assembled system.
For pressure- or temperature-sensitive applications, provide the tube specification and operating conditions for review.
Bulkhead Mounting & Configuration
The SV Series is designed to provide a fixed straight tube connection through a panel, enclosure or equipment wall.
The fitting passes through the mounting surface and is secured by the bulkhead locking arrangement. The two tube connections remain aligned on opposite sides of the panel.
Installation dimensions vary according to the selected L or S series and tube O.D.
When specifying the fitting, provide the tube size together with the available mounting-space or panel requirements where these dimensions are critical.
Size & Configuration Information
Each SV Series Hydraulic Bulkhead Union connects two metric tubes of the same outside diameter in a straight through-panel configuration.
Dimensions, body thread, wrench sizes and ordering numbers vary by tube O.D. and L or S series.
Configuration-specific dimensional and mounting information can be provided for quotation and technical review.
Materials
316 stainless steel is the standard material for this series.
Material selection should take into account the fluid medium, operating environment, temperature and corrosion requirements.
Specify the required material together with the tube O.D., series and quantity when requesting a quotation.
Installation & System Considerations
Correct assembly is important to the performance of both the 24° hydraulic tube connections and the bulkhead mounting arrangement.
The mounting surface should provide sufficient clearance for the fitting body and locking components. The fitting should be securely mounted without introducing unintended stress or misalignment into the connected tubing.
Tube preparation and cutting-ring assembly should follow the applicable assembly procedure for the selected tube size and series.
Tube dimensions, wall thickness and material should be compatible with the selected fitting configuration.
For installations with restricted panel space or specific mounting requirements, provide the relevant installation dimensions for review.
Typical Applications
