24 mm pressure regulating bottle screw cap (membrane liner seal)

Vented liner enables airflow and prevents packaging deformations for even the most highly concentrated chemicals

For releasing and consuming gases, temperature differences and altitude changes

Allows bottles to breathe, equalizing pressure and reducing condensation while filtering out liquids and other contaminants

Bottles won’t bulge or collapse

Sealing: degassing / aeration membrane liner (cap thread venting)

   - Only allowing air and gas molecules to pass through the membrane

   - Permits pressure equalisation and tight sealing

   - Closure allows two-way venting for either pressure or vacuum relief

 Cap size: 24-410 , 24 mm

Standard colour: black / white (other colours available on request)
