There is generally one main reason why “Viton” seals are used within air cylinders instead of traditional Buna-N or Carboxylated Nitrile rubber material seals. The reason is that Viton material can withstand higher temperatures up to approximately 400° F while standard Buna and carboxylated materials can only withstand temperatures up to approximately 250° F. There are also other seal materials available for higher temperature applications. Contact Peninsular at (800) 526-7968 in the USA or Canada or at (586) 775-7211 if additional information on this subject is required. You may also e-mail us at sales@peninsularcylinders.com.

For high heat applications it is very important to know the temperature surrounding the cylinder. Some other important questions that must be made known to Peninsular include the following:

What is the temperature ?
Is this temperature constant or intermittent ?
How often does the cylinder cycle ?
Are there temperature variances at the cylinder, or is the temperature constant ? If yes, what are the high and low temperatures ?
Is there any hot material making physical contact with the cylinder? If so, what part
of the cylinder is being contacted by this hot material ?

Your communication back to Peninsular will allow us to determine the correct seal material to use when manufacturing your cylinder. Note, Viton Seals are not considered standard seal material and must be ordered separately.

Although Viton seal materials do not contain the same wear characteristics as Buna-N and Carboxylated nitrile rubber type seals, they are highly effective in combating high heat conditions that may be present in certain applications.

Peninsular’s team of Fluid Power Engineers will assist you with high temperature applications and provide recommendations for various types of seal materials to meet your specific requirements when excessive heat conditions are present. Viton seals are a popular solution to many types of heat problems that effect pneumatic cylinders.

When you select Viton seals to be used within your cylinder a /V will become present in the Peninsular cylinder part number after you have submitted the cylinder for configuration.
