Harmsco BF55C/105SC/155SC Tank Lid Gasket (O-290)

A tank lid gasket helps create a seal between a compatible tank body and lid assembly, and this version is designed for Harmsco BF55C, 105SC, and 155SC related applications using the O-290 reference. When a lid gasket becomes flattened, brittle, or damaged, the tank can lose the secure closure it should maintain.

The multi-model Harmsco fitment gives this gasket practical value because tank lid seals work best when the replacement matches the intended vessel family and lid profile. A properly selected gasket helps support cleaner sealing and contributes to more dependable tank performance.

This type of part is especially useful during tank service, inspection, or routine maintenance when the lid is already being removed and the seal should be renewed before reassembly. That keeps the repair targeted and more dependable.

Installed in the proper application, this gasket helps support dependable tank lid sealing and contributes to cleaner overall system integrity.
