Description
This isn’t your average small O-ring. It’s a lengthy cord made from high-quality silicone rubber, supplied in a continuous length. You can cut it to the exact size you need for your repair. This makes it a versatile and essential part for many maintenance jobs on Busch R5 series pumps.
Silicone rubber is a great material for many sealing jobs. It has some special qualities that make it perfect for certain spots in a vacuum pump.
First, silicone stays very flexible across a wide range of temperatures. It doesn’t get stiff in the cold or break down too quickly in the heat common inside a pump. This flexibility helps it create a tight, snug seal.
Second, silicone is generally good at resisting compression. This means it can be squeezed between two parts and will bounce back to its shape, keeping the seal effective for a long time
