The Metric Compression Fittings range is NORMA Group Manufactured with a high level of quality for product peace of mind. These fittings are UV stabilized to ensure they will continue to perform, even in the harsh Australian sun. NORMA Metric Compression Fittings are the ideal connection for PE Pipe made in accordance to AS/NZS 4130. They are WaterMark approved to have a 50 year design life. The o’ring sits in a relaxed state when the fitting is loose to allow less friction upon insertion which means the nuts do not need to be removed to insert the pipe. The two stage seal means the o’ring is pushed into a second stage of the body to increase seal ability. It is easily identified as a metric compression fitting by having blue nuts. The fittings are interchangeable with the NORMA rural components. There are a large range of sizes and configurations available to cover all types of installation.
