When you buy Parker O-Rings, there are some factors that you should consider when making a purchase. These factors include the materials used, hardness, and sizing. Then, you’ll know exactly how to use these o-rings for your application. To make your decision easier, follow these tips. This article explains some of the main factors that you should take into consideration. Make sure to read each of the sections and make an informed decision!
Factors to consider
Whether you are in the market for a new or replacement Parker O-Ring, you should take a few factors into account. Parker has a system for part numbering its products, and you can identify them by polymers, compounds, and hardness. It also has a vast array of products available in its catalog. You can also request a custom product if your business has very specific needs, such as a piston seal or filter seal.
O-Rings are among the most popular types of seals in the world, and the brand Parker O-Ring is one of the most renowned manufacturers. These o-rings are available in a wide range of materials, so you can find the right one for any application. As a global supplier of precision-engineered o-rings, Parker has been manufacturing reliable products for over seventy years. Parker O-Ring Division has been an industry leader since 1944, and the company is one of the leading providers of quality o-rings.
Another factor to consider when buying Parker O-Ring: the thickness of the o-rings. The o-ring material should be able to resist external factors for a longer time. In addition to thickness, other factors such as chemical compatibility should be considered before purchasing a particular o-ring. In addition to the thickness, the material’s elongation capacity should be able to stretch over ledges or fittings.
What are the signs that the O-ring is failing? These can vary widely depending on the chemical media used. Blistering, cracks, and changes in hardness are all signs of a bad O-ring. Other signs include discolouration and uneven hardness. Some elastomers react to certain chemicals, causing them to increase their cross-link density. This makes the material harder and brittle, and can cause the seal to break down and shrink.
The type of material: Depending on the application, there are several types of synthetic rubber that you can choose from. While synthetic rubber provides good chemical resistance and oil resistance, it also has a wide temperature range. The typical hardness range of an O-ring is around 40 to 90 durometer. The materials used in automotive and chemical processing are also available in custom colors. Some o-rings can also be manufactured from vegetable fiber, PTFE, or Aflas(r).
Materials
Whether you’re a mechanical engineer or an automotive engineer, you may be wondering which materials to buy Parker O-Rings in. There are many benefits to synthetic rubber over other materials. They are highly resistant to heat, oil, and flame. They are also available in a wide range of standard and custom colors. If you need more flexibility, you may want to consider vegetable fiber, PTFE, or Aflas(r).
The most popular choice for industrial O-Rings is polyurethane. Polyurethane is an organic polymer, created by reacting polyol with diisocyanate. Polyurethane is used widely in a wide variety of applications due to its excellent tear and permeation resistance. These O-rings are available in a variety of materials, including silicone, FKM, and EPDM.
When choosing the best material to use for a particular application, be sure to consult with a manufacturer that offers a variety of options. Purchasing from a manufacturer that can customize a product to fit your needs can be a great way to reduce your costs and improve the quality of your end product. When you buy Parker O-Rings, you’ll be working with a company that specializes in materials and seals, and they have the best selection available.
There are several types of materials to choose from when purchasing Parker O-Rings, and a comprehensive o-ring size chart can help you determine which material is best for your needs. To help you choose the right materials, Parker has created a handy tool called the Parker O-Ring Selector. By selecting the correct o-ring, you can ensure that your parts will function properly. If you have a special need, you can also find a manufacturer that offers custom o-rings made of unique materials.
While you may have many choices when choosing materials for Parker O-Rings, you should remember that each material offers a different set of benefits and features. Some materials are ideal for high-temperature and chemical applications, while others are prone to degrading under harsh conditions. Consider what the oil or chemicals in your application will be like and what kind of pressure the O-ring will need to perform. You might also need tear or abrasion resistance.
Hardness
When selecting a new O-ring for a machine, it’s important to consider the hardness of the rubber material. When sealing high pressure fluids, harder materials are better, while soft materials are better for delicate hardware. When choosing a new O-ring, you can trust that Parker will test it to the industry standard Shore A hardness test before approving it for use. The following is a guide to determine the hardness of a Parker O-Ring.
A simple way to determine the hardness of a Parker O-Ring is to use its part numbering system. Parker O-rings have part numbers that identify them by hardness and polymer. A knowledgeable Parker o-ring specialist can help you make the right choice for your machine. Parker has over 100 different products in their catalog, including o-rings, O-ring kits, custom piston seals, and filter seals. They can even customize a product to meet your exact requirements at southwest supply.
An O-ring’s hardness determines how much friction it will endure in the process of running and breaking. A hard compound will be more resistant to running friction than breakout friction. Conversely, a harder compound will require a higher compressive load to squeeze into a cavity. This means that a hard O-ring will have a lower coefficient of friction, which will increase its effectiveness in preventing leaks and leaking.
The IRHD hardness scale is the standard in the O-ring industry. The IRHD scale has several problems associated with the Shore A measurement, including the curved cross-section of the O-ring. Because of this, hardness measurements in the IRHD scale aren’t necessarily accurate. In addition, the hardness of a Parker O-Ring is affected by the curved cross-section.
Sizing
Sizing Parker O-Rings can be a tricky task. Thankfully, there are tools available that will help you choose the right size and material. With this guide, you’ll know what size you need and how to make your selection. With the help of the o-ring sizing chart, you can have your o-rings fit perfectly. If you don’t know what size you need, you can also use the Parker O-Ring Selector to figure out which size will fit your needs.
A universal o-ring size gauge is another helpful tool. It is a special measurement device manufactured by the Parker Seal Group. It consists of a plastic cone with uniquely-marked markings and a separate pi tape. These are used to determine the closest standard 2-dash size for a Parker O-Ring. While the cone does not measure the actual size of the o-ring, you can use it to check the correct diameter and other dimensions of the o-ring. The cone and tape are sold separately.
In addition to the sizing chart, a manual describing the o-ring’s characteristics and application will be available. The handbook provides dimensions for metric and nominal o-ring sizes. The charts also list the material and shrinkage percentage for each type. These dimensions correspond to AS568A standards. If you are not sure how to determine the proper size of a Parker o-ring, a manual can help you make the right choice.
