Overview
The W Series Single Ferrule Hydraulic Union Elbow connects two metric tubes of the same outside diameter while changing the tubing direction by 90 degrees.
Both ends use the 24° cutting-ring connection system, providing a tube-to-tube elbow configuration without a pipe-thread connection.
LL, L and S series are available for different metric tube sizes and system requirements.

Working Pressure
Working pressure varies according to the selected tube series and tube O.D.
Series / Tube O.D. | Working Pressure |
|---|---|
LL: 4–12 mm | 100 bar / 1450 psi |
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.
Size & Configuration Information
Each W Series Hydraulic Union Elbow connects two metric tubes of the same outside diameter in a 90° configuration.
Dimensions and ordering numbers vary by tube O.D. and LL, L or S series. Configuration-specific dimensional 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 a 24° hydraulic tube connection.
Tube preparation and cutting-ring assembly should follow the applicable assembly procedure for the selected tube size and series. Both tube ends should be correctly aligned with the elbow to avoid unintended loading during installation.
Tube dimensions, wall thickness and material should be compatible with the selected fitting configuration.
For critical hydraulic applications, provide the complete tube specification and operating conditions for review.
