Atlas Copco 0663615600 O-Rings M159.30ID x 5.70 SECT

Atlas Copco 0663615600 is an OEM O-ring sized M159.30ID x 5.70 SECT, designed for sealing in Atlas Copco air compressor assemblies. It provides a large-diameter, 159.30 mm internal diameter with a 5.70 mm cross-section, making it suitable for high-capacity seals in compressor housings and valve interfaces where a durable, pressurized seal is required. In official parts catalogs this part is listed as 0663615600 and is commonly referenced as 0663-7556-00 in some listings, both indicating the same M159.30 × 5.70 geometry for a genuine Atlas Copco sealing component. This O-ring is intended to withstand the operating conditions of oil-injected screw compressors and similar Atlas Copco equipment, helping reduce leaks and maintain reliable performance during maintenance and service intervals.
