Copaltite Sealant for Compressors
Copaltite seals compressor cylinder covers, valve cover joints, suction and discharge line connections, and inter-stage piping flanges against high-pressure gas, hydrocarbons, refrigerants, and process media. Effective from -315°F to 1500°F, it is the trusted compressor joint sealant for oil and gas, petrochemical, refrigeration, and industrial compression systems across the UAE and GCC.
Why Compressor Joints Demand a High-Performance Sealant
Compressors are high-cycle machines that subject every joint to continuous mechanical vibration, pressure fluctuation between suction and discharge conditions, and significant temperature variation as the gas is compressed and cooled. These dynamic stresses cause standard sealants to fatigue, crack, and fail in service — allowing gas leakage that reduces compressor efficiency, creates a safety hazard, and leads to costly unplanned maintenance.
Gas compressors in the GCC's oil and gas sector handle hydrocarbons, hydrogen sulphide, carbon dioxide, and sour gas streams that are both aggressively corrosive and potentially dangerous if they escape from a failed joint. Refrigeration compressors handle refrigerants that are expensive to lose and environmentally regulated. Industrial air compressors operate at pressures that make joint integrity a safety requirement. In every case, the sealant must provide a reliable, long-lasting seal under dynamic conditions.
Frequently Asked Questions
Copaltite Cement Form is the preferred sealant for compressor cylinder heads and valve cover joints — particularly on aged or scored mating surfaces. For machined discharge connections and threaded fittings, Copaltite Liquid Form provides a clean, tight seal.
Yes. Copaltite resists refrigerants, hydrocarbons, propane, ammonia, brine, and acids — covering all common compressor process media in refrigeration, gas processing, and petrochemical compression service.
Yes. Copaltite cures to a tough, elastomeric seal that absorbs mechanical vibration without cracking or delaminating — one of its most important properties for high-cycle compressor applications.
