The 9-inch threaded cap is a larger, specialized option designed for applications requiring wider access, such as inserting agitators, dip tubes, or handling high-viscosity liquids.
A solid (non-vented) cap provides a 100% airtight seal, preventing leaks, contamination, and evaporation. It is especially suitable for products like paints, adhesives, and odor-sensitive chemicals, as it blocks oxygen and contains fumes effectively.
Material & Manufacturing
The IBC threaded cap is produced באמצעות injection molding of High-Density Polyethylene (HDPE)-the same material used for IBC inner tanks.
HDPE offers:
Excellent resistance to chemicals, acids, and alkalis
High impact strength and durability
Optional FDA compliance for food and pharmaceutical use
UV resistance with stabilizers for outdoor storage
Recyclability, supporting sustainability goals
An O-ring gasket ensures leak-proof sealing, with three common material options:
