Set of lower and upper gaskets (2 pieces) for the RGV Fresch Quality SV 300 vacuum sealer. These are the original sealing-chamber spare parts: the gasket ensures the airtight seal between the lid and the base during the cycle, allowing the pump to reach the vacuum and hold it until the bag is sealed.

The SV 300 is a semi-professional vacuum packing machine with suction down to -900 mbar, a double parallel 30 cm sealing bar and 230 V ~ 50 Hz power supply (180 W). A seal in good condition is essential to achieve full vacuum and a secure weld.

When to replace them: with use, the gaskets dry out, flatten or get cut, and the machine no longer reaches the vacuum, loses it slowly, or completes the cycle without drawing air correctly. Replacing both gaskets restores the original seal.

• Compatibility: RGV Fresch Quality SV 300
• Contents: lower gasket + upper gasket (2 pieces)
• Function: airtight chamber seal for reaching and holding the vacuum

Tip: keep the gaskets clean and free of residue; check their condition after repeated cycles and replace the pair when the machine struggles to pull a vacuum.
