Maximize Seal Reliability with DuraClear Engineered Lubricants

Mechanical seals face some of the toughest conditions in any plant—exposure to dirty, contaminated, hot, and chemically aggressive fluids that can cause rapid wear, leakage, and premature failure. Inadequate lubrication leads to increased friction, heat generation, and costly downtime.

SCG Process offers DuraClear engineered lubricants, formulated specifically for mechanical seal barrier and buffer systems. These fully synthetic, high-performance fluids provide the stability, protection, and compatibility needed to extend seal life and reduce maintenance across your entire plant.

Product Grades for Every Application

DuraClear 5-F (ISO 5) and 32-F (ISO 32) are the workhorse lubricants of the DuraClear line—fully synthetic, PAO-based oils designed for chemical, petrochemical, refinery, and pipeline environments.
These formulations outperform traditional mineral oils with better film strength, oxidation resistance, and thermal performance, covering the majority of barrier and buffer fluid needs plant-wide.

Engineered Lubrication for the Toughest Applications

Unlike general-purpose lubricants, DuraClear oils are designed to meet the complex lubrication demands of modern mechanical seals. Whether operating in chemical processing, refining, or pipeline service, DuraClear delivers superior film strength, thermal stability, and chemical compatibility—ensuring seals perform reliably even in extreme process conditions.

Compatible with All Seal Face Materials:

DuraClear lubricants are engineered to perform under hard vs. hard and hard vs. soft seal combinations without causing blistering, glazing, or surface damage. Compatible with:

  • Carbon
  • Silicon Carbide
  • Tungsten Carbide
