What is the most durable O-ring material?

Fluorocarbon (Viton®) Offering outstanding chemical and high-temperature resistance, fluorocarbon O-rings are among the most durable and versatile available. They are particularly valuable in aircraft engines and automotive fuel handling systems because they resist swell in high-octane and oxygenated fuels.

Can I use RTV instead of an O-ring?

It is fine to use the correct RTV sealant instead of a gasket if used in the right application (oil, high temp, fuel).

What makes an O-ring a good seal?

The pressure of the contained fluid transfers through the essentially incompressible O-ring material, and the contact stress rises with increasing pressure. For this reason, an O-ring can easily seal high pressure as long as it does not fail mechanically.

What is the most common O-ring material?

Silicone
Nitrile (Buna), Neoprene, Ethylene Propylene (EPDM Rubber), Silicone, Fluorocarbon (Viton), and PTFE (Teflon) are among the most commonly used compounds for O-rings and seals.

What material can I use to make a gasket?

The following examples are some of the most common and versatile non-metallic materials we use for gasket making.

• Natural rubber. It’s a popular choice for a reason — natural rubber is a good all-around, general-purpose gasket material.
• Silicone rubber.
• Neoprene rubber.
• Neoprene sponge.
• Cork.
• Compressed non-asbestos.

Is gasket maker as good as a gasket?

Gasket makers and flange sealants are great time savers to have on hand in the shop. And, when compared to a traditional gasket, the material costs for gasket makers are much less. They can eliminate leak paths that traditional gaskets can’t, and they’re super-resistant to vibration, fluids, and temperature cycles.

What causes O ring leak?

The most common causes of O-Ring failures include: Improper gland design, allowing for too much or too little compression, not enough for seal expansion and tolerance stack-up. Improper O-Ring installation. Inadequate O-Ring lubrication.

What are cheap O-rings made of?

Some of the common types of O-ring materials include PTFE, Nitrile (Buna), Neoprene, EPDM Rubber and Fluorocarbon (Viton). Silicone and Kalrez® O-ring materials are also widely used, especially in high temperature applications.
