Cerulean N 04LT: Low-Temperature NBR Seals with Oil Resistance
Cerulean N 04LT is specially compounded for low-temperature resistance, offering good mechanical strength, oil resistance and good abrasion resistance down to -55°C. This makes it a dependable choice for valves, pumps, mechanical seals and compressors operating in cold environments where standard NBR grades tend to stiffen and crack.

Cerulean N 04LT properties
ISMAT manufactures Cerulean N 04LT using premium raw materials, validated through in-house testing to confirm consistent quality across every batch. This NBR compound is specially formulated for extreme low-temperature resistance, holding its flexibility and sealing force down to -55°C without hardening or cracking, while retaining the oil and abrasion resistance NBR is known for.
That combination makes it well suited for valves, pumps, mechanical seals and compressors operating in cold climates or refrigeration-adjacent environments, where seal failure due to low-temperature stiffening is a common risk with standard-grade NBR.
