Description

O-rings are used to block a path which may otherwise allow a liquid or a gas to escape. The o ring is placed into a groove to secure them in place, and then compressed between two surfaces. When the system comes under pressure, the o ring is squeezed against the opposite wall of the groove, maintaining a perfect seal even under very high or low pressures.

We stock them in 4 types:

NBR: Standard use. Common in automotive parts due to fuel/oil/etc resistance that ordinary rubber does not have. Can be used for moderate temperatures (-40°C to 121°C)

Viton: Great for high temp (-29°C to 204°C). In general, this material is compatible with hydrocarbons, but incompatible with acetones, ketones, steam, hot water, and organic acids.

Silicone: Generally non-reactive, stable, and resistant to extreme environments. It can be used in extreme high temperatures (-60°C to 232°C) while still maintaining its useful properties. Silicone’s temperature tolerance helps it avoid brittleness in freezing conditions and maintain its dimensional tolerance at extremely high temps.

EPDM: EPDM rubber is suitable for used in moderate cold temperatures and is resistant to steam (-51°C to 150°C). Also used for and outdoor applications, hot water, direct sunlight/UV, silicone oils and greases, dilute acids, ketones, alkalis, and automotive brake fluids. It also makes an excellent electrical insulator.

Teflon: Teflon o-rings are known for high heat resistance (-200°C to 250°C), high resistance to chemical agents and solvents, anti-adhesiveness, dielectric properties, low friction coefficient, and non-toxicity.

They also come in different hardnesses:

Standard NBR and EPDM is 70A, and 90A is harder

Standard Viton is 75A, and 90A is harder

Standard Silicone is 70A, and 80A is harder

Standard Teflon is 55D (Shore D is a harder scale than the softer Shore A of other o-rings)
