Is the Flange End 90° Interlock SAE 6000, Carbon Steel Connector compatible with hose types 4SH, R13, and R15 for high-pressure applications?

Yes. The Flange End 90° Interlock SAE 6000, Carbon Steel Connector is compatible with high‑pressure hose types 4SH, R13, and R15. It is engineered for demanding hydraulic service, features an O‑ring or gasket in the flange groove for reliable sealing, and its interlock design prevents hose blow‑off. Made from high‑quality carbon steel with a protective galvanization finish, it resists corrosion and is suitable for heavy‑duty applications such as construction, mining, and industrial machinery.

Does the Flange End 90° Interlock SAE 6000, Carbon Steel Connector require a specific O-ring material for compatibility with different hydraulic fluids?

Flange End 90° Interlock SAE 6000, Carbon Steel Connector: Yes — the connector uses an O-ring (or alternative gasket) located in the flange groove, so O-ring material selection is important for compatibility with different hydraulic fluids and operating conditions. Common considerations: - Mineral oil-based hydraulic fluids: Nitrile (NBR) is widely used and generally compatible for standard temperature ranges. - Phosphate ester (fire-resistant) fluids: HNBR, FKM (Viton) or specific polymers often required for chemical compatibility and higher temperature resistance. - Water-glycol or water-based fluids: EPDM is typically preferred for resistance to water and glycol mixtures. - Synthetic esters or biodegradable fluids: FKM or specially formulated elastomers may be necessary; compatibility charts should be checked. - Extreme temperatures or aggressive chemicals: HNBR, FKM or specialty fluorosilicones may be recommended. Always verify fluid compatibility and temperature/pressure requirements with O-ring manufacturer data and the hydraulic system specifications. When in doubt, consult the connector/fitting supplier for recommended O-ring materials for your specific fluid and service conditions.
