Description
A shaft seal might look like a simple ring of rubber and metal, but it is a critical part that keeps your vacuum pump running smoothly. The VacStellar Shaft Seal, 52 x 68 x 8 (Part # 487547735) is a replacement part, built to the same high standards as the original equipment.
This seal is specially designed for the Busch COBRA NC0630B dry screw vacuum pump. It is a key component of the official Busch COBRA NC0630B Gasket Kit (Part # 990543930). Its main job is to seal the gap where a rotating shaft passes through a stationary housing. Think of it as a tough, reliable barrier that keeps oil in and dirt out.
