If you need a new o-ring, Parker offers a variety of options. There are aggressive and high-temperature chemistries, as well as various compounds. If you are looking for a particular size, consider a size selector. Listed below are a few reasons to buy Parker O-Rings. After reading this article, you will be well-equipped to make an informed choice.
High-temperature and aggressive chemistries
The company has a broad selection of O-Rings in various materials and sizes, as well as custom-molded, metal, and silicone profiles. Their 74-page Sealing Guide details the company’s capabilities in these areas, and the company’s Controlled Batch Identification (CBI) program helps ensure that the materials are produced to exacting standards. Despite being manufactured to very tight tolerances, Parker O-Rings are made to withstand high temperatures and aggressive chemistries.
Fluorocarbon and PTFE O-Rings are two of the most common material combinations used in industrial applications, and both offer high-temperature and chemical resistance. FEP/P O-rings are particularly useful for high-temperature applications, while silicone O-rings are excellent for static applications. These materials are ideal for a variety of applications, and they are available in both rigid and flexible designs.
Perfluoroelastomer parts are also available, including SZ489 perfluoroelastomer parts. SZ489 has a broad operating temperature range between -14deg F and 500 deg F, and its Tensile Mpa (Psi) rating is 18.7 (27110). It is also recommended that this material be used in applications involving aggressive dry-process chemistries and reactive plasmas, as they are less likely to rupture.
Polyurethane o-rings are durable and easy to install. They have low thermal expansion coefficients, minimal shrinkage, and virtually no tendency to twist. Their tensile strength and stiffness make them the ideal choice for high-temperature applications. They’re also easy to install and are ideal for harsh environments. They are also chemical-resistant, and they can be used in a variety of environments.
Parofluor elastomer is an elastomer with a combination of chemical resistance and elastic properties. Parofluor has excellent chemical and fluid resistance, and is highly resistant to petroleum-based fuels and flex cracking. Parker offers Parofluor materials in glass-filled and unmodified formulations. These materials are made of a proprietary polytetrafluoroethylene material.
O-Rings are used in a variety of industries, including hydraulic systems, pneumatic components, and heavy-duty mobile applications. Life sciences include diagnostic & lab equipment and pharmaceutical manufacturing. Military applications include weapons and transportation, and other transportation including subways and railways. A company must adhere to all applicable regulatory and statutory requirements for its products. So, if you’re looking for an O-Ring, look no further!
If you’re in need of an O-Ring, you’ll be delighted to know that Parker offers an extensive selection of sizes and compounds for a variety of applications. The company’s 74-page Sealing Guide outlines the vast range of options available through the Parker O-Ring Division. The company prides itself on supplying high-quality O-Rings that perform reliably and effectively in a variety of environments.
Parker polyacrylate o-rings are manufactured with copolymers of ethyl and acrylates. They resist the corrosion and oxidation associated with petroleum-based fluids. These rings are measured based on the inside diameter, and the most common inch size is SAE AS568C. Other sizes include ISO 3601-1:2012, which lists common sizes. If you need an o-ring to be resistant to high temperatures and pressures, Parker’s Pradifa Ultrathane (r) is a versatile, low-friction material that provides unmatched performance.
There are two basic types of Parker O-Rings compounds. One is ethylene propylene, while the other is elastomer-based and can be either polyurethane or a copolymer. Either type will provide excellent heat and chemical resistance, and is also resistant to water, alkali, and mild acidic solvents. If you’re interested in finding out more about each of these compounds, please visit the Parker material data sheet.
Both the materials and processes used for compounding Parker O-Rings comply with the stringent requirements of the FDA and EPA. The compounds used by the company’s O-Rings Division are approved for use in the United Kingdom, Germany, and North America. The company has partnered with Parker Seals for 50 years and is one of the few distributors of Southwest Supply to become a “Parker Seal Technology Center.”
For standard O-Rings, Parker Hannifin uses the 70-durometer hard nitrile compound, while its 90-durometer compound is for tube fittings and adapters. Buna-Nitrile elastomer is valued by seal professionals for its price and resistance properties. It is also resistant to water, oxygenated solvents, ozone, and sunlight, but experts don’t recommend using it in gasoline or hydrocarbon environments.
Parker Pradifa Ultrathan(r) O-rings are made of a new material that reduces the need for backup rings and reduces the necessary groove width for pneumatic valves. The new material can also be installed in an undercut and closed housings, and can also be used in existing O-ring grooves. This material is resistant to heat, oxygen, and many organic solvents. Whether you’re looking for a high-temperature resistance o-ring or something with a low-compression set, Parker O-rings will deliver you the best possible sealing performance.
Neoprene is a general-purpose elastomer with a low compression set. It is resistant to abrasion and flexes cracking. Fluorocarbon O-rings, meanwhile, combine chemical and high-temperature resistance. They are widely used in the automotive and aerospace industries, and some advanced grades are even capable of withstanding 450°F. There are numerous types of Parker O-Rings compounds.
For choosing the right size of Parker O-Rings, a size selector is an invaluable tool. The Parker size chart gives you a list of available sizes, as well as metric and nominal dimensions. You can even find the size in the form of a metric number. To choose the proper size, look for the corresponding AS568A dimension. A metric number indicates a smaller o-ring than a nominal one.
Parker’s O-Ring Selector is a useful engineering tool, offering material and size selections. The two dimensions are interrelated, with imperial and metric values listed. Using the size selector, you can select the best o-ring material for your application. This tool can also help you understand what size fits which material. By referencing the chart, you can quickly identify the proper o-ring size for your machine.
The size selector for Parker O-Rings has extensive parameterization options. The tool produces reliable results. The three-part structure of the tool is intuitive and logical, which makes it a valuable tool for engineers and technicians. It’s also compatible with both metric and imperial standards. This tool provides an easy-to-use guide to determining O-Ring size, so you can buy the best fit the first time.
Once you have entered the desired O-ring size in the size selector, you can choose a fitting O-ring. The size selector uses several factors to determine the correct dimensions. The user enters the 2-425 O-ring code to find the proper size. The result displays the diameter and cross-section of the O-ring, the tolerances, and the gland fill. Additionally, the total deformation force, the amount of force required to seal the hardware, is listed. The selected size is then displayed.
