Coventry™ 12803 Heptane Precision Swelling and Cleaning Solvent

Coventry™ Heptane Solvent is a highly purified grade of n-heptane, providing the cleanest chemical grade available. This high-purity solvent was developed to swell silicone and urethane elastomers and tubing for fitment onto components, and then evaporate allowing the tubing to shrink back to its original dimensions. It is also used as a silicone lubricant carrier fluid for devices. Coventry Heptane Precision Cleaning Solvent is engineered to offer a low residue, high purity grade of solvent excelling in operations that require high solvency and very low residue. Heptane is not water-soluble, colorless and volatile liquid with a hydrocarbon odor.

Coventry Heptane Precision Cleaning Solvent is used to clean and prepare a variety of surfaces within critical environments:
• Swelling elastomers
• Carrier fluid for depositing silicone lubricants
• Cleaning
• Extraction
• Drying agent


  • Exceeds reagent grade purity
  • Swelling of platinum and peroxide cured silicone
  • Deposition of silicone lubricants
  • Cleaning solvent for critical cleaning applications
  • Removes greases and waxes from hard impervious surfaces
  • Low surface tension
  • Evaporates quickly and leaves no residues, minimizes process time
  • No ozone depleting chemicals


Keeping it Fresh - Acid Acceptance Testing for Vapor Degreasing Solvents

Vapor degreasers are very efficient at removing soils from a variety of surfaces. And maintaining its efficient operation is relatively easy. One concern that arises with the use of vapor degreasers is the determination of when the solvent used in the degreaser is spent, which can mean t...
