Engineered for reliability beyond standard hydraulic oil, the 6300, 6600, and associated series are your trusted solution for conveying a wide range of media—from anti-freeze and water to lubricants and return-line fluids. Built to exceed stringent SAE specifications, these hoses are designed to deliver consistent performance in medium to low-pressure applications, even under high operating temperatures.
Broad Media Compatibility: Reliably transmits hydraulic oil, anti-freeze, water, lubricants, and air.
Superior High-Temperature Performance: Most series offer HT (High-Temp) variants, ensuring stable operation in demanding thermal environments.
Comprehensive Pressure Range: Covers medium to low-pressure applications, including dedicated return-line solutions.
Global Standard Certification: Complies with and exceeds international standards including SAE 100R3, 100R4, 100R5, and 100R6.
