Food-grade o-rings have been manufactured to more exacting standards of material composition, such that theyve been officially declared food safe for use in the production and preparation of meals, beverages and dining products. Without extensive experience in sealing, it can be difficult to determine which elastomer is right for a given project. Some common food-safe o-ring materials include EPDM, fluorocarbon, nitrile, neoprene and silicone. Fluorocarbons primary limitation is an intolerance to low temperatures and certain chemicals, such as ketones, amines, low molecular weight esters, and ethers. Its also important that the components being joined together in a dynamic environment are carefully designed and finished, such that they will not abrade, shear and eventually destroy the O-ring positioned between them. The wider the clearance, the higher the probability for the o-ring to be extruded. This can lead to an unreliable seal in the short term, and over time the CO2 will actually cause the o-ring to start to break down from within.

In high pressure applications, the right O-ring is critical to prevent seal failure, we will work with you to help you find the perfect high pressure O-ring to fit your application. If you need additional help or require custom o-ring specifications, dont hesitate to contact us and wed be happy to help. Butyl is the classic choice for vacuum-sealing, providing extremely low permeability to gases. Provided the internal pressure from fluids being contained stays below a given O-ring's contact stress rating, its largely impossible for leaks to occur, even under high pressure. Need a compound not shown here or not sure what is best for your application. Silicone can be formulated in a variety colors, durometer hardnesses and variations designed for use in a wide range of demanding specialty applications like medical and EMI shielding. Although silicone is well-known for medical-grade and FDA-compliant sealing applications, silicone rubber is also a solid choice for extreme temperature static sealing due to its heat and cold resistance. Polytetrafluoroethylene (PTFE) O-rings are designed to be used in harsh environments with temperatures ranging from -450F to 600F. Unfortunately, due to polytetrafluoroethylene material properties, pure PTFE O-rings are very rigid and hard to apply. Available in standard translucent or black 70 or 90 durometer, with custom colors available. Some popular choices for use in applications where the o-ring will have extended CO2 contact include polyurethane, PTFE, nitrile, and fluoroelastomers. We offer a wide variety of high-pressure O-ring materials. High pressure O-rings are needed in a large variety of industries. These materials offer excellent chemcial and high temperature resistance. Arizona Sealing Devices, Inc. EP can be formulated in a variety of ways for use in a wide range of demanding specialty applications.

O-Rings can withstand higher pressures in static applications compared to dynamic applications. This can occur at less than half the pressure of what it normally takes to cause extrusion. Food-grade o-rings have been manufactured to more exacting standards of material composition, such that theyve been officially declared food safe for use in the production and preparation of meals, beverages and dining products. Without extensive experience in sealing, it can be difficult to determine which elastomer is right for a given project. Some common food-safe o-ring materials include EPDM, fluorocarbon, nitrile, neoprene and silicone. Fluorocarbons primary limitation is an intolerance to low temperatures and certain chemicals, such as ketones, amines, low molecular weight esters, and ethers. Its also important that the components being joined together in a dynamic environment are carefully designed and finished, such that they will not abrade, shear and eventually destroy the O-ring positioned between them. The wider the clearance, the higher the probability for the o-ring to be extruded. This can lead to an unreliable seal in the short term, and over time the CO2 will actually cause the o-ring to start to break down from within.
Abrasion and tear resistance may also be of importance, especially in dynamic applications or when abrasive substances are involved. Offered in three resin options with temperature resistance up to 392-572F/200-300C. A synthetic rubber/elastomer providing excellent heat, oil, acid, weather and flame resistance. PTFE O-rings are compatible with the widest range of chemicals, such as acetone, isopropyl, methyl, etc.
