Select the tube series and tube O.D. according to the required system configuration and operating conditions.
Working Pressure
Working pressure varies according to the selected tube series and tube size.
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.
Size & Configuration Information
The GZ Series combines a 24° cutting-ring tube connection with a straight swivel connection. Tube O.D., L or S series and the corresponding metric connection vary by configuration. Dimensions and ordering numbers are series- and size-specific.
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. The swivel connection should be correctly matched to the corresponding metric interface and assembled without unintended loading or misalignment.
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.
