Graphite Seals

Description
Carbon graphite is an ideal seal material in every aspect. It’s impervious and resistant to most chemicals. Carbon graphite seals are one of the most important solutions for those looking for a sealing material that seals tightly and offers several other important characteristics. Seals are an important part of any machine because they often determine whether it will operate efficiently and without breaking down.

Performance
1. Graphite seals are self lubricating and resistant to chemicals, corrosion and oxidation.
2. They feature low coefficient of friction, good thermal conductivity, excellent mechanical strength, and dimensional stability under wide temperature variations.
3. Carbon graphite seals can be applied in corrosive environments, chemical pumps, steam joints, food processing pumps, process pumps in refineries, cold and hot water pumps, agitators and mixers, and cryogenic applications.

How to Choose a Graphite Seal?
When choosing a company to manufacture your carbon graphite seals, you should ask some questions first.
1. Find out what process they use to create the seals and how long it would take them to create a seal that can meet your specifications.
2. Ask the shapes and sizes of the graphite seal they have, as well as the tolerances they are able to hold.
Knowing the answers to these questions will help you discover whether this company can and will provide you with a quality carbon graphite seal. After all, if the seal breaks, the entire machine will be affected, so you should choose wisely.
