Atlas Copco Gasket Replacement – 1622792400

Atlas Copco 1622792400 – Gasket

The Atlas Copco 1622792400 (1622-7924-00) Gasket is a sealing component used in Atlas Copco compressor equipment. Its primary function is to create a reliable, leak-resistant seal between two mating surfaces within the compressor assembly.

Working Process:
During assembly, the gasket is positioned between two accurately machined mating surfaces. When the connecting bolts or fasteners are tightened, the gasket is compressed between the surfaces. This compression allows the gasket material to fill minor surface irregularities and maintain a continuous sealing barrier.

During compressor operation, internal air, oil, or other process fluids may be present around the joint. The gasket prevents these fluids from escaping through the connection while also helping prevent unwanted air or contaminants from entering the assembly. The gasket therefore supports the integrity of the compressor’s sealed circuit and helps maintain stable operating conditions.

The gasket must maintain sufficient compression and sealing capability under the temperature, pressure, vibration, and operating conditions of the compressor. If the gasket becomes hardened, damaged, compressed excessively, or loses its sealing properties, leakage may occur. This can result in pressure loss, oil leakage, reduced compressor efficiency, or contamination of surrounding components.

During scheduled maintenance or component replacement, the old gasket should normally be removed and the mating surfaces inspected and cleaned before installing the replacement. Correct installation and proper tightening of the associated fasteners help ensure uniform gasket compression and reliable long-term sealing.
