3/4 Low Pressure Hydraulic Hose – Reliable Fluid Transfer for Industrial Systems
1. Product Overview
Our 3/4 low pressure hydraulic hose is engineered to deliver consistent performance in return lines, suction lines, and low-pressure hydraulic systems. Designed with a synthetic rubber inner tube and a textile reinforcement layer, this hose provides excellent flexibility and resistance to oil, water, and mild chemicals. With a working pressure range suitable for low-demand applications, it serves as a cost-effective solution for general industrial fluid transfer without compromising on durability.
The 3/4-inch inner diameter (19.0 mm) offers a balanced flow capacity, making it a popular choice for hydraulic power units, lubrication systems, and agricultural machinery. Whether you need to replace worn-out lines or build a new circuit, this hose ensures reliable operation under moderate pressure conditions.
2. Key Features
- Flexible & Lightweight: The textile reinforcement allows tight bending radii, simplifying installation in confined spaces.
- Oil & Abrasion Resistant: The synthetic rubber cover withstands exposure to hydraulic fluids, grease, and mechanical wear.
- Temperature Range: Operates effectively from -40°C to +100°C (-40°F to +212°F), suitable for both cold and warm environments.
- Cost-Effective: Ideal for low-pressure circuits where high-pressure spiral hoses are unnecessary.
- Compliant Standards: Meets SAE 100 R1 and R2 specifications for low-pressure hydraulic applications.

7. FAQ
Q: What is the difference between a 3/4 low pressure hydraulic hose and a high-pressure hose?
A: Low-pressure hoses use textile reinforcement and are rated for up to 350 psi. High-pressure hoses use steel wire braids or spirals for pressures exceeding 1,000 psi. The 3/4 low pressure hydraulic hose is ideal for return lines and suction applications where high pressure is not required.
Q: Can this hose be used for water or air?
A: Yes, it is suitable for water, air, and mineral oils. However, for hot water above 100°C or aggressive chemicals, please consult our technical team for a specialized hose recommendation.
Q: What fittings are compatible?
A: Standard 3/4-inch (19 mm) fittings with JIC 37°, NPT, or BSP threads are compatible. We recommend using crimp fittings for a secure, leak-proof connection.
Q: What is the shelf life of this hose?
A: When stored in a cool, dry place away from direct sunlight and ozone sources, the hose can be stored for up to 5 years without performance degradation.
Q: Do you offer samples?
A: Yes, we provide free samples (up to 1 meter) for qualified B2B buyers. Simply contact our sales team with your request.
