Our premium PTFE O-Ring is custom manufactured for use with the J-7 Aerosol Can-Emitor and recommended for use with acidic aerosols. Designed to seal the top lid of the J-7 Aerosol Can-Emitor to the lower base, and prevent the leakage of liquids and propellants, this O-Ring has a thickness of approximately 1/8” and a diameter of approximately 3 1/2”.

Our PTFE O-Ring is made of polytetrafluoroethylene (commonly known as Teflon) and is extremely long-lasting and durable, even in the presence of corrosive and caustic fluids. PTFE is unaffected by most known acids, alkalis and solvents, and resistant to oxidation and chemical corrosion.
