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 |
|---|---|
LL: 4–8 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 K Series Hydraulic Union Cross connects four metric tubes of the same outside diameter in an equal cross 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° cutting-ring connection.
Tube preparation, cutting-ring orientation and tightening should follow the applicable assembly procedure for the selected tube size and series. All four tube connections should be assembled using compatible tube specifications and appropriate installation procedures.
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.
