Venting Cap for PP Carboys with TPE Gasket — 13 mm and 6 mm Ports

Cap designed for controlled venting on laboratory carboys. Polypropylene body with TPE gasket for a liquid-tight seal on the carboy neck. Unused ports are sealed with included port plugs.

Features

• Body material: Polypropylene (PP)
• Gasket: TPE — liquid-tight seal on the carboy
• Main port: Accepts 13 mm internal diameter silicone tubing
• Secondary port: Accepts 6 mm internal diameter silicone tubing
• Port plugs: Included to seal ports when not in use

Typical Applications

Liquid waste collection set-ups, gravity or soft-vacuum transfer systems, and storage carboys requiring controlled venting. Common in chemistry, pharmaceutical, and waste management laboratories where pressure equalisation is needed without opening the carboy.

The 13 mm port handles standard-bore silicone tubing for medium flow rates. The 6 mm port is suited to passive venting or lower-flow lines.

Chemical Compatibility

PP resists most dilute acids, bases, and polar solvents typically encountered in the laboratory. Check compatibility before use with concentrated halogenated solvents or strong oxidising acids. The TPE gasket remains flexible and maintains the seal across a wide working temperature range.
