This silicone gasket has a solid square profile, 8x8 mm, designed to seal the lid and chamber on vacuum chamber packaging machines, providing the airtight seal needed to reach vacuum during the sealing cycle. It is the 'without lip' version: the cross-section is solid and uniform, unlike the lipped version, which is thinner on one side and designed for different housing types. This determines where it should be fitted: it suits housings designed for a solid profile, typically along the chamber rim or as a bar-counter gasket.

The gasket is sold by the meter: simply specify the length required when ordering, and it will be cut to size according to the actual perimeter to be sealed.

It is the correct replacement part when the original gasket shows clear signs of wear: loss of elasticity, hardened or cracked surface, visible deformation along the profile. The most common symptom calling for replacement is insufficient or irregular vacuum at the end of the cycle, with the machine struggling to reach the set pressure or losing it right after sealing.
