Product Information

O rings are often used in plumbing applications to help prevent leaking between one pipe and another pipe. You will find them in your bathroom and kitchen faucet, and at connectors or fittings. Food-grade o-rings have been manufactured to more exacting standards of material composition, such that they’ve been officially declared ‘food safe’ for use in the production and preparation of meals, beverages and dining products. Best food grade O-ring seal materials Applications: Life Science Industry, Pharmaceutical & Medical applications, Food & Beverage manufacturing, Drinking water applications. Applications: Polyurethane o-rings are often used for hydraulic fittings, cylinders and valves, pneumatic tools, and firearms. Avoid: Silicone exhibits poor tear resistance, abrasion, and tensile strength. The poor abrasion resistance means they are better suited for static applications than dynamic. They do perform well with water, steam or petroleum fluids, either.

The most common type of O ring is the elastomeric O ring. Elastomeric O rings are made from synthetic rubber elastomer material with excellent resistance that can deform elastically (or stretch) without breaking with an elastomeric seal. This makes them ideal for use in applications where there may be some movement or vibration. Sensitive to weather influences, moderate temperature resistance, unsuitable for brake fluid and polar solvents There are a number of popular high-temperature o-ring material choices, including nitrile, hydrogenated nitrile, silicone rubber, polyacrylate and more. Securing the best choice in any given scenario will generally be a balancing act between the specific operating temperature needed, and the most economical material option at that performance point. Avoid: Similar to nitrile, EPR is not perfect for a wide range of applications due to wear and tear issues. O-rings are circular elastic loops that serve as seals for both stationary and moving applications. Their primary function is to provide a sealing mechanism between structures, such as pipes, tubes, pistons, and cylinders. Depending on the intended use, o-rings are manufactured using different materials and are highly flexible.Find out how to silence your water heater once and for all with our guide.

Good resistance to oils and solvents such as aliphatic, aromatic and halocarbons, acids, animal and vegetable oils; not resistant to methanol It also helps to speed up installation, helping to seat o rings perfectly into position. Spray vs. grease – which ones best

This makes them ideal for demanding industries and environments such as oil and gas refineries, chemical processing, or any other scenario where a high-temperature seal is required, such as performance transport applications like turbo engines and aerospace engineering. Best O-ring seal materials for high temperaturesUse a rubber indicator test to determine the material of the existing o-ring; this helps get a suitable o-ring replacement. What are the various types of o-ring materials? Petroleum-based products can cause elastomeric rubber to swell or dry out. Solvents are not ideal lubricants and contain high Volatile Organic Compounds (VOCs) that may be flammable or pose very real health risks. Soap and water solutions are safer solutions than solvents and petroleum-based lubricants, but are nominal, inconsistent, and reactivated in wet or damp environments after assembly. As we mentioned earlier, plumber’s grease is primarily used for all kinds of faucets. If you are having an issue with a stiff or squeaking fixture, taking apart the faucet and applying plumber’s silicone grease after a good cleaning should help your issue.

Plumbing o-ring choices are widespread, given the range of materials, sizes and gauges available for use in ducting and pipework applications, as well as to form tight waterproof seals around taps and other fittings. Choosing the best product for the job depends on finding the correct size and shape for the specific role you have in mind. Food Grade O-ring seals We mentioned Vaseline is similar, but since most faucet seals and O-rings are made of Nitrile Butadiene Rubber, Vaseline can break down the products in it and ruin the seals. It’s not just o rings that silicone lubricant bunnings are used on either. Due to its versatile offering, you will also find it helpful and used within: As o rings are made from synthetic rubbers such as Neoprene, nitrile, and EPDM, you can use petroleum grease to perfectly lubricate the o ring.Determine the hardness: The hardness of the o-ring determines its ability to resist extrusion and deformation. Hardness is measured in a durometer and can range from 30-90. For example, an o-ring with a durometer reading of 60 is softer than 70, while 90 is stiff compared to a reading of 70. O rings are also used in many other applications, such as in automotive and mechanical engineering. They have many benefits.
