Different elastomers for o rings and various applications

An elastomer is a primary raw material used for most o rings. They are typically manufactured as gum rubber or manufactured synthetically, and surprisingly today, there are approximately over 32 different synthetic rubbers now available.  Elastomer compounds will...

Spiral wound gasket thickness – what’s best?

It is often recommended that using a thinner gasket type/material will result in better sealing performance.  Why?  Because thinner gaskets tend to require much less gasket stress to provide applications with the perfect seal, they also have an excellent response to...

Choosing the correct oil seal application

Choosing and using the proper sealing devices within oil and gas applications can be vital when preventing dirt, dust, water, and other debris from potentially getting inside and contaminating products.  Of course, all rubber materials and seals will provide a range...

Nitrile rubber, NBR, and Buna-N – how well do you know your o ring materials?

A widely used elastomer, Nitrile, Buna-N, or NBR rubber, are all oil and fuel resistant and provide a great level of strength, making them a popular material for seals across various industries.  Suitable for a range of applications, this versatile rubber material,...

Optimum squeezing force for an o ring

It is true that the more squeeze you place on an o ring, the tighter the seal it will provide. In essence, the more squeeze (compression) you apply, the greater the force between the o ring and its mating hardware.  And ensuring you have the perfect seal is all...

O Ring Squeeze

The squeeze and shrinkage on an o ring are vital to understanding as these factors stand in the way of your application either experiencing a perfect seal or your application suffering from leaks.  You can measure the shrinkage of an o ring during...

Keeping your o rings bonded

EMI o rings. Those seal ring gaskets are made of silicone compounds, combining environmental sealing with electromagnetic interference protection.  Consisting of metal or metal-coated particles, silicone o rings are filled with silver, silver aluminium, or nickel...

Tips for Proper O-Ring Installation

Tips for Proper O-Ring InstallationAn O-ring is a crucial component of a fluid system, and how it is installed can make or break that system. To ensure the success of an application, O-ring requires not only careful material selection and design but also proper installation procedures. A small mistake during installation can result in untold damage.  Fortunately, there are simple tricks you can employ during O-ring installation to avert any problems that are associated with poor installation including: 

Choose the Right Size O-ring 

It is imperative that you choose the right O-ring size for your needs. Using an inappropriate O-ring size in an application can result in damage.   However, it can be difficult to measure O-rings at the workplace if you don’t have proper measuring equipment. Fortunately, you can get specialised tools from reputable O-ring suppliers, such as Specialist Sealing Products, which are geared to help you chose the right O-ring size for your application.  

Employ Good Design Practices 

Another great trick to ensure proper O-ring installation is to install the O-ring according to the manufacturer’s good design practices.  For example, you should consider the defined O-ring dimensions to uphold adequate compression on the O-ring without surpassing the capacity of the grove.

Use the Right O-ring Lubricant 

It is imperative that you lubricate O-rings before installation. You can simply apply a thin film of mineral oil, silicone oil, grease, or application fluid. This will help minimise friction between the sealing ring and the surface with which it is paired. As such it ensures that the ring fits in the groove quite easily.   Lubrication also helps to minimise the potential for seal damage and twisting. In fact, when you use the right lubricant for male and female radial seals, you will have an easier time during seal installation and when inserting the piston in the bore.   When it comes to selecting the right lubricant, you should keep your system in mind. You want a lubricating agent that is well-suited for the O-ring material that you’re using. The lubricating agent should meet the following requirements: 

  • Appropriate for the application’s temperature range 
  • Works well with the system fluids 
  • Able to produce a highsurface tension film 
  • Should not clog up system filters

Apply The Right Amount of Torque When Tightening Tube Fitting 

The amount of torque needed when tightening an O-ring tube fitting varies with the design of the tube fitting. However, as a general rule, you need to ensure that the mating halves of the fitting bottoms-out with metal-to-metal contact. Consider contacting the tube fitting’s manufacturer if you need detailed information.   It is also worth noting that proper seal installation requires that you use proper installation tool kits.  With the above O-ring installation tips, you’ll be able to prevent O-ring installation issues such as overstretching and improper gland volume, as well as failure without evidence.   You can get a wide range of high-quality O-rings from Special Sealing Products.
