Is the 45° Interlock SAE 3000 Flange End, Carbon Steel compatible with hose types 4SH, R13, and R15 for high-pressure hydraulic systems?

Yes. The 45° Interlock SAE 3000 Flange End, Carbon Steel is compatible with hose types 4SH, R13, and R15 for high-pressure hydraulic systems. It is engineered to handle demanding, high-pressure applications, offers an interlock design for enhanced hose retention, and uses an O-ring or gasket in a dedicated groove to ensure secure, leak-free seals. Made from carbon steel with a protective galvanization layer, it provides corrosion resistance and durability suited to heavy-duty environments like construction, mining, and heavy machinery.

How does the O-ring groove design on the 45° Interlock SAE 3000 Flange End, Carbon Steel ensure long-term leak prevention under extreme pressure and vibration?

The O-ring groove on the 45° Interlock SAE 3000 Flange End, Carbon Steel Format is engineered for durable, leak-free performance under extreme pressure and vibration by combining precise geometry, material compatibility, and protective features: - Precision groove fit: The groove dimensions match the O-ring profile to maintain uniform compression, preventing extrusion or rolling under fluctuating loads and ensuring a consistent sealing surface even when pressures spike. - Optimal O-ring compression: The groove depth and width provide the correct squeeze for the selected O-ring material, balancing sufficient deformation for seal contact without overstressing the elastomer, which preserves elasticity and lifespan under repeated pressure cycles. - Retention against vibration: The interlock flange geometry secures the hose and limits micro-movements; the O-ring seated in the groove resists displacement during vibration, maintaining continuous contact and preventing transient leakage paths. - Material and surface protection: Carbon steel construction with galvanization protects the groove from corrosion and surface wear that could compromise sealing integrity over time, while a smooth machined groove surface reduces abrasion and O-ring wear. - Compatibility with hose types: Designed for 4SH, R13, and R15 hoses, the groove and O-ring pairing handle the system’s specific pressure ranges and dynamic forces, ensuring the seal performs reliably in heavy-duty applications. Together these features ensure the O-ring groove design on the 45° Interlock SAE 3000 Flange End, Carbon Steel Format minimizes fluid loss and sustains long-term leak prevention under extreme pressure and vibration.
