SW 822 — Anaerobic sealant for hydraulic and pneumatic fittings
Reliability and sealing on threads up to 3/4", resistant to vibration, shock, and aggressive substances.
General description:
SW 822 is a fluid sealant designed for threaded fittings up to 3/4" subject to pressure, mechanical stress, and thermal shock.
It ensures excellent sealing against gas, water, oils, LPG, hydrocarbons, and technical fluids, and offers high resistance to corrosion, vibration, and shock.
It remains removable with standard tools and does not require activators under standard conditions.
The product is recommended by Faiveley Transport for sealing the pneumatic lines of railway rolling stock, and is part of the SW line developed in collaboration with the group.
SW 822 is ideal for:
• Threaded fittings on pneumatic and hydraulic lines
• Systems with water, LPG, gas, mineral and synthetic oils
• Connections subject to vibration or shock
• Hard-to-access fittings requiring a durable yet removable seal
