The Essential Role of 4 Hydraulic Hose in Industrial Systems
Hydraulic systems demand components that withstand extreme pressure cycles while maintaining fluid integrity. The 4 hydraulic hose
specification represents a critical solution meeting international SAE 100R4 standards. Engineered with four spiral steel wires reinforcing synthetic rubber, these hoses deliver minimum 5,800 PSI working pressure across temperatures ranging from -40°F to +212°F. Unlike standard hydraulic lines, 4sh hydraulic hose rubber hose constructions prevent permeation loss below 15cc/m²/day according to ISO 17456 testing protocols.
Technical Advantages of SAE 100R4/4SH Hoses
Performance characteristics make 4SH hydraulic hose rubber hose designs superior for dynamic applications:
- Impulse Resistance: Maintains integrity beyond 250,000 pressure cycles at 150% working pressure (per ISO 6803)
- Flex Life: Soft rubber hose flexible hydraulic hose variants endure 2.3X more bending cycles than standard R2 types
- Temperature Stability: Specialized elastomers reduce hardening below -22°F while resisting oil degradation up to 225°F
- Abrasion Resistance: R5 hydraulic hose rubber compounds show 50% less surface wear in ASTM D3389 testing

FAQS on 4 hydraulic hose
Q: What is a 4 hydraulic hose?
A: A 4 hydraulic hose refers to SAE 100R4 specification rubber hoses for medium-pressure fluid transfer. It handles up to 1,500 PSI in applications like construction machinery. Its synthetic rubber construction ensures flexibility and oil resistance.
Q: How does 4SH hydraulic hose differ from standard rubber hose?
A: SAE 100R4SH hydraulic hoses feature a 4-wire braid reinforcement for higher burst strength. They withstand up to 5,000 PSI vs. lower-grade rubber hoses. The design prioritizes pressure resilience for industrial hydraulic systems.
Q: Why choose soft rubber hose flexible hydraulic hose?
A: Soft rubber hydraulic hoses enable tight-radius bending without kinking. Their flexibility simplifies routing in compact spaces. Rubber materials also resist abrasion and environmental damage.
Q: What does R5 mean in rubber hose R5 hydraulic hose?
A: R5 designates SAE 100R5 hoses for high-temperature applications. These rubber hoses endure up to 257°F (125°C) continuously. They're used in heat-exposed hydraulic circuits like engines.
Q: When should I use 4-series hydraulic hoses?
A: Use SAE 100R4/R4SH hoses for medium-pressure hydraulic systems. They suit construction, agriculture, and industrial tools requiring flexibility. Match hose specs with your system's PSI rating.
