PP retaining plug
- stable, conical, flexible in use

The conical stopper made of robust polypropylene (PP) is used to securely and centrally hold your laboratory pump in small containers and canisters. Thanks to its flexible diameter, it is suitable for container openings from 40 to 58 mm and adapts reliably to different container openings thanks to its conical shape.

The chemical-resistant PP material ensures a long service life and high resistance to aggressive media. The stopper is quick to fit and easy to clean - ideal for frequently changing applications in laboratories and production environments.
