General purpose, high quality cork-elastomer jointing. Below 3mm thickness it comprises predominantly nitrile bonded cork; at 3mm and above the cork is bonded with a polychloroprene/nitrile blend. Previously designated Nebar® N1. Prime features Orginally developed for high pressure applications in switchgear and transformers. Extensively used in the automotive, engineering and electrical industries. Suitable for a wide range of flanges. +110°C maximum operating temperature in liquids. Retains flexibility down to -20°C (<3mm thickness) or -30°C (≥3mm thickness). Easy to cut handle and install. Specifications Complies with ASEA 1169 5012E-204; and ASTM F104 line call out - <3mm, F224000M2; ≥3mm, F225000M2. Fluid compatibilities Suitable for use with air, water, alcohols, fuel and diesel oils, mineral lubricating oils, mineral hydraulic fluids, water/glycol, ASTM Oil No 1, IRM903 oil, ASTM Fuel A, BS 148 Transformer Oil.
