There are a lot of different processes in the manufacturing world. One of them is extrusion. The main purpose of this process is to create products that have a fixed cross section. In comparison to other manufacturing processes, extrusion seems to be advantageous. This is because it allows creating complex cross-sections with materials that are brittle by nature. Extruded products also have a perfect finish. In addition to that, products made by solid rubber extrusion are smooth, soft, biocompatible, have transparency and are resistant to tear.

Manufacturers like Lusida Rubber Products extrude materials like Chloroprene, Butyl, Viton™, Nitrile, Neoprene, SBR, NBR, Natural Rubber and EPDM. In addition to that, the methods employed during manufacturing are approved by FDA.

Apart from solid rubber extrusion, there is sponge rubber extrusion as well. It is quite similar to the former but involves addition of chemicals during processing. This lets you use it for several applications. Most of the extruded products include extruded seals and extrusion seals with wire carrier. These are widely used for different purposes. Extruded seals are used for pumps, mills, industrial equipment, automobiles, construction, fuel tanks, electronic enclosures and much more. In fact, you would find these seals in doors and windows so that wind and water don’t enter into your house.

Extrusion is a process of creating products that have a fixed cross section. Most manufacturers carry out solid rubber extrusion and sponge rubber extrusion. They are used for several applications.

How to select O-Rings

There’s an increasing range of size and material used to make O-Rings in the rubber, plastic and metal industry. The production of O-Rings has gone up recently. The demand of O-Rings is also on the rise. This means that O-Rings are now used for countless reasons. Therefore, you can easily get confused when selecting the best O-Ring for your home/ work use.
In this guide, I give the best tips to use when selecting the right O-Ring for your intended purpose. Please read on.
What is an O Ring?
Also called Toroidal Seal, an O-Ring is a doughnut-shaped object (a torus) that is crafted from an elastomer, and can be used as a seal to stop the flow of fluids.
O-Rings are often simplified and economical products that ship in several forms and can be used for several uses. For instance, you can use an O-Ring as a static seal to replace a sealing washer. You can also use the product as a both single and double acting dynamic seal. Others prefer to use the O-Ring to radially seal cylinders from either internal, external or axial positions.
O-Rings can be manufactured effortlessly, in both small and large volumes depending the required size. This is thanks to their circular form that can be elastic and often features an ring-shaped cross section.
Here some of the common factors to consider when selecting O-Rings:
• The size of the object being sealed – inches or metric
• Predicted applied pressure
• Anticipated temperature levels
• Application type – static or dynamic application
• Type of material – solvent, abrasive, caustic, acid
• If dynamic – speed of moving surfaces
Different instances when you have to select an O-Ring
When replacing an old or damaged seal
• Start by measuring the cross-section “W” to determine if it’s an imperial size (BS 1806), a metric size (BS 4518), or any other metric standard.
• Measure the inside diameter (I.D.) readings of your cylinder using a Vernier caliper to get accurate readings. Bear in mind that an O-Ring is usually differentiated by its I.D. x section – say, 5 x 16. This means you can use these I.D. readings to select the closest O-Ring that’ll fit.
• If you’re not sure, select a sighly larger O-Ring size, given it can easily compress to fit a smaller I.D. – but I advise landing the exact O-Ring size.
When the O-Ring is missing and only have housing metalwork
If somehow you’re lacking an O-Ring but have the shaft, rod or piston, you can use the procedure above to get the right O-Ring.
When at the design stage
• In this instance, you have a series of options. Opt for ex-stock O-Rings both in size and material.
• Ask for customized products when you lack alternatives.
• Stick to commonly preferred material finishes and durability.
• Know how and where the product will be used, whether static or dynamic. This will determine the size and material you’ll select.
For example, temperatures will determine the material of the O-Ring, while the applied pressure will decide the rubber hardness, size of groove and the extrusion gap of the product. This means that if the pressure applied is high, opt for a minimum gap. Alternatively you have to include the back-up washers, and larger grooves.
When factors are unknown
• In this case, I advise performing a rather overall assessment.
• Choose the largest O-Ring section to match the nominal groove I.D. – allows for extreme temperature withstanding and high pressure torelance. It’ll also tolerate several metalwork sizes, and surfaces.
• You should also deliberate how to install the O-Ring – where up to 7% range is allowed, but about 4% of the outside diameter is recommended.
• Apply a considerable squeeze to the cross-section to improve its effectiveness. Avoid applying too much pressure on dynamic uses.
• Maintain the deformation size recommended at the depth of the groove.
• Mind the sizes used when you seal dynamic applications
• Remove all sharp edges and try using fitting tools as well as desirable lubricant when installing
How to select the material used
O-Rings are mostly created from an elastomer called Nitrile 70 Shore ‘A’ (NBR 70). The elastomer can seal a larger part of normal applications, such as water, petrol and oil. These fluids alongside balmy chemicals that record up to 1000 C as well as 1500 psi, offer mating surfaces and adequate housing metalwork.
Bear in mind of the following:
• Low temperatures – often below -350C
• High temperatures
• Hightened pressures
• Hazardous chemicals
The industry is also increasingly demanding for peculiar materials – certified to be used alongside Food Machinery (FDA), and Potable Water (WRC).

All rubber products used in the food processing units are most often exposed to high temperature and pressure settings. They are also likely to come in contact with food and oils during the processing. That is why non-toxic and odor-free food grade rubber is used for the manufacture of seals, hoses, O-rings and gaskets that are used in food processing units. Food grade rubber also has antimicrobial properties and it therefore prevents the growth of microbes including bacteria.

Since US FDA (Food and Drug Administration) has very strict guidelines regarding what kinds of materials can be allowed to come into contact with edible products it is extremely important to maintain the highest standards while handling food items. The aim is to ensure that the food products remain uncontaminated at every stage of processing and reach consumers in perfect condition.

With every passing year there is always advancement in technology in the manufacturing world. However, there are certain things that are still in use for years now and a classic example of that would be the O-ring. It was first patented way back in 1896. It is a loop that resembles the shape of a doughnut used to prevent liquids and gases from passing through it. It is used all over the world for sealing products and has stood the test of time. It is basically a gasket.

The materials that an O-ring is made up of include plastic, metal and rubber. Find the different types of materials listed below:

Fluoroelastomer – This material is used in applications that involve heat. O-rings of this material are long-lasting and resistant to heat.

Silicone rubber – These O-rings are generally used in the food industry as they are non-toxic.
Thermoplastic polyurethane – This material is resistant to degradation.

Ethylene propylene diene monomer – This material is resistant to steam, moisture, grease and silicone.

A classic example of the use of O-rings is in automotive engines. O-rings are used in preventing the oil from getting into the combustion chamber. It may be a rather simple component but it does its job really well.

The O-rings work as a seal by preventing fluids from escaping from the gaps in the two mating hardware surfaces. Usually made out of rubber, these are soft and are mechanically plugged into the hole between two surfaces.

In our daily life we get to see a lot of rubber products in different forms. Almost everything you pick up will have rubber in some form or the other. As you must be aware, rubber is a natural product that is extracted from rubber trees worldwide with Asia being the main source.

Rubber can also be produced synthetically and is used widely in many industrial and household applications. One of the largest consumers of rubber is the automobile industry as it is used in huge amounts to manufacture tires and tubes. Rubber is used to make hoses, belts, gloves for medical uses and much more. It is also used as an adhesive in industries. The reason why rubber is so versatile is because of the fact that it can easily change its shape and form. Additionally, to make rubber harder and stronger it is made to go through a process called vulcanization. It is obvious that when the rubber used is strong by nature, the end product will be durable.
