Gasket for the bell (lid) of the Sirman SP30 vacuum packing machine. It is the rubber/silicone element that ensures the airtight seal between the lid and the tank during the suction cycle: without an intact gasket, the pump cannot reach the correct vacuum level and the packing remains incomplete.

Specifications:

• Compatibility: Sirman SP30 chamber vacuum machine
• Cross-section profile: 5x6 with lip
• Length: 157 cm
• Spare part code: IW1471230010

The gasket should be replaced when the profile is hardened, flattened, cracked or deformed, or when the machine struggles to draw the vacuum, takes longer than usual or does not seal evenly: these are the typical symptoms of a worn-out seal. It is a consumable component subject to natural wear over the working cycles. Practical tip: seat the profile in its groove starting from the corners, without stretching it, and clean the groove before fitting to ensure proper adhesion.
