O – ring, 70 x 5 mm – Viton, Part# PL23970509 – vacstellar

An O-ring is a simple loop of rubber. Its job is to sit in a groove and get squeezed. When squeezed, it fills gaps perfectly to create a seal that keeps fluids in and dirt out.

That’s where this Viton O-ring shines. Viton (its technical name is FKM) is a special, premium elastomer. Think of it as “super rubber.”

It is famous for its amazing resistance. It laughs at high temperatures that would melt other seals. It stays flexible in conditions that would make normal rubber brittle. It also resorts oil, fuel, and many chemicals much better.

This specific seal measures 70 mm in inner diameter and has a 5 mm thick cross-section (noted as 70 x 5 mm). This  Part # PL23970509, ensures it will fit perfectly in its designated groove.
