Product Information

The PVC also provides a significant improvement in solvent resistance, yet maintains similar chemical and physical properties, commonly noted among nitrile elastomers. This is beneficial for special applications where the O-ring has to be fixed by the groove e.g. a lid which opens regularly. Explosive decompression–An O-ring embolism, also called gas expansion rupture, occurs when high pressure gas becomes trapped inside the elastomeric seal element. This expansion causes blisters and ruptures on the surface of the seal.

It is very simple to set up, it transfers data by itself automatically. Definitely, the best monitor overall I had in the past! Silicone rubber (SiR): noted for their ability to be used over a wide temperature range and for excellent resistance to ozone, weathering and aging. Compared with most other sealing elastomers, the physical properties of silicones are poor. Generally, silicone materials are physiologically harmless so they are commonly used by the food and drug industries. Standard silicones are resistant to water up to 212°F (100°C), aliphatic engine and transmission oils and animal and plant oils and fats. Silicones are generally not resistant to fuels, aromatic mineral oils, steam (short term to 248°F (120°C) is possible), silicone oils and greases, acids or alkalis. Fluorosilicone elastomers are far more resistant to oils and fuels. The temperature range of applications is somewhat more restricted. [19]The groove design allows the O-ring to be retained in the face seal during assembly and maintenance. This is why it is important to verify the right size of your O-ring. If you are not sure about which size you have to buy, Wearing a pulse oximeter at night is a perfect way to monitor the low oxygen episodes. The Wellue O2ring does exactly that and much more. What is the Wellue O2ring? We no longer sell travel insurance to new customers, but if you have an existing policy don't worry, you're still covered. If you need medical assistance, or to make a claim, here are the numbers to use. This article is about the mechanical seal. For other uses, see Oring. Typical O-ring and application

Oxygen saturation (SpO2) assesses how much oxygen is in your blood. During waking hours, healthy adults often have an SpO2 of about 95% to 99%, but this may drop by a few percentage points during sleep. When awake, SpO2 levels below 92% may be a sign of insufficient oxygen. Levels below 88% should prompt immediate medical attention. CR is resistant to refrigerants, ammonia, Freon® ( R12, R13, R21, R22, R113, R114, R115, R134A), silicone oils, water, ozone, vegetable oils, alcohols, and low-pressure oxygen. CR has a very low resistance to mineral oils.If the system does not pressurize correctly, the entire piece of equipment has to be disassembled and seals must be replaced. O-Ring - Who Invented the O-Ring?". Inventors.about.com. 2010-06-15. Archived from the original on 2009-03-15 . Retrieved 2011-03-25. If you have any questions about your policy, please call Customer Service: 0844 463 02 02. Lines open Monday-Friday, 9am-5pm. It is resistant to engine oils of all types, engine coolants with high level of rust inhibitors, extreme pressure (EP) gear lubricants, transmission and power steering fluids, and all types of brake fluids including DOT 3, mineral oil, and silicone oil. TFE/P is ideal for heat transfer media, amines, acids and bases, as well as hot water and steam up to +170°C (+340°F).

We have an extensive range of seal materials including Perfluoroelastomer (FFKM), Nitrile (NBR), Hydrogenated Nitrile (HNBR), Kalrez®, Viton™ (or FKM/FPM), Viton™ A, Viton™ B, Viton™ GF, Viton™ GLT, Viton™ GFLT, Viton™ ETP, Ethylene Propylene (EPDM), Silicone (VMQ), Polytetrafluoroethylene (PTFE) Fluorosilicone (FVMQ) and Medical Grade. These can all be measured to imperial (BS1806, ISO 3601) and metric (BS4518) sizes, shore hardness and to a range of International, National and industry specifications, grades and approval standards. Cleaning: To clean your O2 Ring, moisten a soft cloth with water or alcohol and gently wipe the device. Don’t use acetone or other volatile cleaners.Spiral failure–Found on long-stroke piston seals and – to a lesser degree – on rod seals. The seal gets "hung up" at one point on its diameter (against the cylinder wall) and slides and rolls at the same time. This twists the O-ring as the sealed device is cycled and finally causes a series of deep spiral cuts (typically at a 45 degree angle) on the surface of the seal. Their name, as implied, simply refers to a classic doughnut or torus shape, and they exist purely to create a better, more leak-proof seal between two other components, with the aim usually being to prevent the unwanted escape of gases or liquids. In this sense, they’re effectively a type of gasket - the main difference being that o-rings are more commonly used in very high-pressure environments, where a normal cork, paper or rubber gasket would likely be prone to failure. If you do not use the correct tools to install an O-ring, your O-ring might become damaged when it is fitted. Avoid sharp parts that may damage the O-ring. The Oximeter binary file can now be imported into OSCAR and will have the same start time as your CPAP data.

O-rings are usually produced using a variety of manufacturing techniques like extrusion, injection molding, pressure molding or transfer molding. I was diagnosed moderate sleep apnea and they wanted me to use a CPAP. I wanted to explore every option and found this. Been wearing it good 2 months now and LOVE it! I’m actually finding the positions in which my oxygen goes down and trying to avoid those positions and retrain myself. This would even be good for non sleep monitoring.Silicone is resistant to hot air, ozone, UV radiation, engine and transmission oils, animal and vegetable fats and oils, and brake fluids. VMQ also has low resistance to mineral oils. Silicone can be compounded to be electrically resistant, conductive, or flame retardant. O-ring selection is based on chemical compatibility, application temperature, sealing pressure, lubrication requirements, durometer, size and cost. [18] Silicones are a group of elastomeric materials made from silicone, oxygen, hydrogen, and carbon. Extreme temperature range and low temperature flexibility are characteristics of silicone compounds. As a group, silicones have poor tensile strength, tear resistance, and abrasion resistance.
