Global O-Ring Nitrile (Buna-N) O-Ring Kit – 90 Durometer Black, 200 Pieces in 12 AS568 Sizes – High-Pressure Seals for Automotive, Hydraulic, and Industrial Applications

The Global O-Ring Nitrile (Buna-N) O-Ring Kit – 90 Durometer Black is a practical and cost-effective sealing solution designed for high-pressure automotive, hydraulic, and industrial applications. This kit includes 200 precision-molded O-rings in 12 of the most commonly used AS568 sizes, offering excellent value and convenience for maintenance professionals and repair technicians. Manufactured from Nitrile rubber (Buna-N or NBR), these O-rings are well known for their resistance to petroleum-based oils and fuels, making them a reliable choice for fluid handling systems. The 90 durometer hardness provides increased strength and extrusion resistance compared to softer compounds, helping maintain seal integrity in higher-pressure or tighter-clearance applications
