ISO 6149 Metric Port Tube Fitting O-Rings

ISO 6149 Metric Tube Fitting O-Rings are Buna-N 90 durometer O-Rings made for metric straight thread ports and hydraulic tube fittings. This ISO standard uses 13 O-Ring sizes, with each size matched to a specific metric thread. These seals are commonly used in hydraulic systems, metric tube fittings, fluid power equipment, industrial machinery, and repair work where a firm, oil-resistant seal is needed. Buna-N, also called Nitrile or NBR, is a strong everyday choice because it offers good wear resistance, low cost, and dependable sealing with petroleum oils, lubricants, water, propane, natural gas, and many hydraulic and pneumatic fluids. The 90 durometer hardness gives the O-Ring extra strength for higher-pressure port sealing compared to softer 70 durometer seals. Buna-N is not the best choice for sunlight, ozone, outdoor weather, strong acids, ketones, or harsh chemicals. This category helps customers quickly find the correct ISO 6149 O-Ring by metric thread size, reducing guesswork and helping prevent leaks, downtime, and wrong-size orders. The O-Ring Store LLC stocks these seals to make ordering metric hydraulic port O-Rings easier, faster, and more reliable.
