O-ring, 2.57 x 1.78 mm – Viton, Part# 23974102 – vacstellar

This O-ring creates a perfect, airtight seal between two parts. Think of it like a tiny, super-strong rubber washer. It gets squeezed between surfaces to block any path for air.

It is made from Viton. This is a special material that is great for vacuum and industrial uses. Viton is much more resistant to heat, oils, and chemicals than regular rubber. This means the seal lasts longer and performs better in tough conditions.

Using the exact size and material is crucial. This 2.57 mm x 1.78 mm O-ring is designed to fit specific grooves in Alcatel Adixen equipment. The right fit ensures a reliable seal every time.

O-rings are consumable parts. Over time, they can flatten, crack, or lose elasticity. Replacing them with a , Viton O-ring like this one is a low-cost way to protect the performance and longevity of your expensive vacuum equipment.
