ROCOL Gasseal Non-Setting Sealant is a non-setting pipe sealant used for metallic threaded joints. It is non-corrosive to aluminium, brass, copper, low carbon steel, and zinc. This sealant is suitable for use with natural gas and LPG pipework, allowing joints to be assembled and pressure tested immediately. It also resists vibration and is compatible with foam-forming leak testers. Independently tested by BSI to BS EN 751-2: 1997 Part 2 Class B, it operates within a temperature range of -20°C to 125°C. Rocol Gasseal is an off-white sealing compound ideal for LPG, natural gas, air, and water, making it a reliable choice for threaded pipe fittings in domestic and industrial gas systems.
