Metabo HPT/Hitachi 877315 877-315 Cylinder O-Ring 63.9 for NR83A, NR83A2, NR83AA, NR83AA2 (4-Pack)

The Metabo HPT (formerly Hitachi) 877315 Cylinder O-Ring, with an inner diameter of 63.9 mm, is a crucial replacement part designed for various models of nailers, specifically the NR83A, NR83A2, NR83AA, and NR83AA2. This high-quality O-ring is engineered to create an air-tight seal within the cylinder, ensuring optimal performance by allowing the tool to build necessary pressure effectively. Over time, O-rings can wear out or crack due to regular use, which may lead to decreased efficiency or malfunctioning of the nailer. Replacing the old O-ring with the 877315 model helps restore the tool's functionality, making it run like new again. This part is recognized for its durability and reliability, making it an essential component for maintaining the performance of the compatible nailers.
