Light yellow biodegradable hydraulic fluid in a one-quart bottle

Renewable Lubricants

Renewable Lubricants Biodegradable Hydraulic Fluid 1 Qt ISO 32 81631

SKU CH-C5SB-8S3MX

Biodegradable hydraulic fluid with ISO 32 viscosity operates from -20 to 250 degrees F in a 1 qt bottle

  • Biodegradable vegetable-oil base reduces environmental impact
  • ISO 32 viscosity matches wide hydraulic-system requirements
  • Operates from -20 °F to 250 °F for seasonal reliability
  • High 186 viscosity index maintains film strength across temperatures
  • 550 °F flash point adds fire-safety margin

Biodegradable Hydraulic Fluid ISO 32

Renewable Lubricants Biodegradable Hydraulic Fluid is an ISO Viscosity Grade 32 fluid formulated with a vegetable oil base. It is suited for hydraulic systems requiring biodegradable lubrication in environmentally sensitive areas. The light yellow fluid comes in a one-quart bottle identified by part number 81631.

Operating Range -20 to 250 Degrees F

The fluid operates from a minimum of -20 degrees F to a maximum of 250 degrees F. A pour point of -31 degrees F supports cold-weather start-up, while a flash point of 550 degrees F indicates high-temperature stability. A viscosity index of 186 shows consistent viscosity across the temperature range.

Replaces Conventional Petroleum Hydraulic Oils

This product replaces conventional petroleum-based hydraulic oils where biodegradability is required. The switch is worth it for operations needing a vegetable oil base fluid that meets ISO 32 viscosity without a specific NSF rating. It is not for systems requiring a different ISO viscosity grade or an NSF-rated lubricant.

Questions about this item

How do I fill the system with this ISO 32 biodegradable hydraulic fluid without introducing air?

Drain the old fluid completely, then pour the 1 qt bottle slowly into the reservoir while cycling the pump at low pressure to bleed air from the lines.

When should I replace this vegetable-oil based hydraulic fluid?

Monitor viscosity index 186 and colour; change the fluid if it darkens significantly or if operating temperatures regularly approach the 250 °F limit.

What is the first performance limit reached during continuous high-load operation?

The maximum operating temperature of 250 °F is the primary limit; sustained heat above this degrades the vegetable base oil and reduces the 186 viscosity index protection.
