Frequently Asked Questions (FAQ)
This plastic lid is specifically designed for bulk liquid containers featuring a DN225 nominal diameter with an S245×6 standard thread opening.
The lid-in-lid structure allows you to unscrew only the inner plug cap for small-volume liquid feeding or sampling without opening the entire main cover, saving operation time and preventing unnecessary liquid evaporation.
A solid inner cap provides complete airtight sealing for standard liquid containment. A vented inner cap allows gas equalization, preventing pressure build-up inside containers storing off-gassing or volatile liquids.
High Density Polyethylene (HDPE) offers high impact strength and chemical resistance against mild acids, alkalis, detergents, and industrial reagents within an operating temperature range of -20℃ to +60℃.
Always ensure the rubber sealing gasket is properly seated inside the outer cover, check that the container thread is clean of debris, and tighten the lid manually clockwise until firm without over-torquing.
