Description
Overview:
The Seal Ring 3/8" is a genuine Atlas Copco sealing component for hydraulic power packs, including the LP 9-20 and LP18-30E. Produced from a durable black elastomer suited to hydraulic oil environments, it provides a reliable barrier against fluid loss at 3/8 in (9.53 mm) connections. By maintaining pressure and preventing leaks, it helps protect pumps, valves, hoses, and quick couplers from premature wear. This OEM part is engineered to match Atlas Copco tolerances for consistent fit and performance, helping restore correct sealing during routine maintenance or repairs. Supplied to OEM specification under part number 3377 0163 75, it is a straightforward replacement that supports safe, efficient operation of Atlas Copco portable hydraulic equipment used on site and in workshops.
