Hydraulic Hose for Air Compressor? Was Told Not to Use It
I'm nearly finished with my air compressor build. It’s a 5hp, 80-gallon, 15cfm unit. I visited a local auto parts store to get a hose. This store isn't a chain; they sell parts, rebuild motors, and turn cranks—real hands-on work.
I went to get a hydraulic hose made to connect my air compressor pump to my aftercooler. I explained my needs to the salesperson, but he initially refused to make the hose, saying it wouldn’t work. He explained that the hose would crystallize inside and shrink. He said they once had such a hose on a compressor that shrank to the size of a pencil. He firmly stated you can't use hydraulic hose on an air compressor; you need copper or some specific type of rubber hose. He did say he would make whatever I wanted, but reiterated that it wouldn't work for long.
So, I'm asking the community, am I wrong? I’ve heard several times that using hydraulic hose for connections on air compressors works fine. I need a short hose between cylinders on the V-twin compressor pump. Additionally, I need a hose from the pump to the aftercooler, which will be mounted on the wall, and another hose from the aftercooler to the tank.
Looking for suggestions,
Scott

What’s Special About Compressor Oil?
Functions:
Transmission and hydraulic oil have many tasks to perform, leaving minimal margin for error. Let's review their functions:
1) Prevents wear on high-torque, heavy-loaded gears and bearings.
2) Provides wear and corrosion protection for the hydraulic pump.
3) Ensures proper friction for clutches to engage and absorb shock loads without slipping or abrupt shifts.
4) Withstands extreme pressures in the hydraulic system without breaking down.
5) Prevents deposit formation on all internal parts.
6) Guards against foam and water damage to all internal parts.
7) Provides proper friction for brakes, ensuring low chatter, long life, and high capacity.
HY-GARD AND LOW-VISCOSITY HY-GARD TRANSMISSION AND HYDRAULIC OIL
Hy-Gard and Low-Viscosity Hy-Gard oils, developed by John Deere engineers, meet the specific needs of John Deere machines. Both are multi-viscosity fluids with high-viscosity index. Low-Viscosity Hy-Gard has an ISO 32 Viscosity Grade, while Hy-Gard falls between ISO 46 and 68. Hy-Gard can be used in applications requiring either grade. Low-Viscosity Hy-Gard serves as a replacement for Hy-Gard in cold weather.
Applications:
- Hy-Gard formula is designed for John Deere equipment but can also be used in many non-John Deere transmission and hydraulic systems.
- Low-Viscosity Hy-Gard is used for factory fill in many machines. Check the machine’s operator’s manual for specifics. It also replaces Hy-Gard in cold-weather applications.
- Low-Viscosity Hy-Gard replaces John Deere All-Weather Hydrostatic Fluid and should be used as a direct replacement where recommended.
- It is compatible with hydrostatic fluid and can be added to systems containing hydrostatic fluid.
Features:
- Lab and field tests, approved by John Deere engineers, meet the increased demands for transmission and hydraulic system performance and protection.
- Polymeric viscosity improver ensures optimal viscosity over operating temperatures. Efficient flow is crucial; oil that’s too light causes wear, while oil that’s too heavy results in sluggish operation and lower efficiency.
- Reduces wet-brake chatter and ensures high braking capacity.
- Enhances wet-clutch performance for smooth operation.
- High resistance to water contamination without sludge formation, preventing filter clogging and hydraulic malfunction. Its anti-oxidation property ensures proper functioning at high temperatures, keeping parts clean.
- Protects against rust and corrosion, especially during low-use periods.
- Anti-wear additives minimize gear and bearing wear. Its extreme-pressure film helps prevent metal-to-metal contact.
