Designed specifically for refrigeration and HVAC systems, Durlon 8700 uses a neoprene (CR) binder to resist ozone, refrigerants, and non-aromatic solvents. Its superior flexibility and tight seal retention at low temperatures make it the go-to choice for compressors, chillers, and cold-storage infrastructure. Rated to 1,500 psi and intermittent heat up to 548°F (287°C).
