Flask Gaskets

SciMac PTFE Gasket provides outstanding chemical resistance for duties where hygiene and non-contamination are essential. SciMac 401 Gaskets are made from Virgin PTFE® that is pressed to create a corrugated surface providing an excellent seal. Use of a clamp for total pressure on the gasket helps to create a vacuumed tight seal. PTFE gaskets offer an alternative to using grease as a lubricant to make the seal between the flanges. Gaskets made of PTFE are resistant to chemical corrosion. The can also withstand high temperature environments. The temperatures range is -260C to 315C (-450F to 600F).
