Tips for best o ring maintenance

If o rings are not maintained, leaks can occur, and water and other fluids can enter the appliance or application, and even product in the mix!  If this happens, damage can occur to internal parts and mechanisms, causing deployment failings, potential false readings,...

What you need to know about O Ring Lubricants

Silicone grease and lubricants aren’t just a nice to have for o rings, but they can quite often be a must-have.  However, with so many greases and lubricants to choose from, it can often be a minefield choosing the best ones and the right ones for your o ring and...

O Ring Replacement

Replacing an O Ring in pressure washer wands is probably one of the most common replacements you'll find when working with seals.  Unfortunately, O Rings don't last forever, and over time they do deteriorate, and you will require an O Ring replacement.  It's important...

Reasons behind seal failure and a look into seal replacement

Unfortunately, there are occasions where O-rings, in particular, fail.  The failure of these seals is not simply due to one factor, but various factors that can occur across a range of applications – hence why locating the exact cause of such problems is just that, a...

Gaskets and seals for Aerospace

Gaskets and seals used for aerospace applications and equipment must be of premium quality and to a substantially high standard.  They are used across a range of applications such as radars, antennas, lighting, access panels, electrical conductivity, pressure sealing,...

Finding the best sealing materials for Food Grade Applications

You will find rubber seals across various industries, providing an important element and operating as a vital fixing across a wide range of different applications and equipment.  However, these FDA gaskets must follow strict, set guidelines, in terms of their material...

The Evolution of Gasket Solutions

When we talk about gaskets and the history of a gasket, we must start at the very beginning.  What is a gasket?  Ultimately, a gasket is a manufactured seal that is used to fill the gap/space between two or more surfaces.  Gaskets are typically manufactured by cutting...

How to preserve your gasket

Gaskets and seals don’t last forever. However, they are designed, or they should be, last for a considerable period.  In this sense, it is vital to look at ways to preserve your gaskets in order to avoid any application downtime.  Downtime that involves additional...

Important Design Features of Rubber Sealings

When it comes to designing the perfect rubber sealing, there are a few design features to bear in mind to help achieve the optimum solution.  In this post, we explore these rubber sealing features further and provide information on the benefits and best uses for these...

Optimal Squeeze for an O Ring to be effective

A doughnut-shaped seal that is primarily used to stop liquids and air from escaping or getting into specific spaces is the function and role of an O Ring.  Also known as a mechanical gasket, O rings are designed to fit between a groove and a compression during the...

Are your gaskets completely compliant?

Are your gaskets completely compliant.jpgIn industries where gaskets are not just important but essential, there are numerous challenges to be faced and considerations to take on board.  This is especially true when it comes to making sure this “essential” element is also compliant. 

With the implementation of stricter standards and new measures to address accountability, can you afford for your manway gaskets to be non-compliant? 

Today, this accountability surrounds being responsible for Non-Accident Releases (NARs) and how a business manages these is of the utmost importance. 

Common problems with manways 

The most common issues found with manway gaskets and man lid door seals include: 

  • Loose bolts 
  • Missing gaskets 
  • Deteriorated gaskets, and 
  • Misaligned gaskets 

All of these issues relate to manway door seals and man lid door seals and often occur due to the varying compression sets / creep they face.  These compression sets occur regardless of whether you’re using a rubber gasket or Teflon material type gasket and do impact on sealing, hence affecting NARs in a big way. 

You may often find that additional torquing may also be required when bolts to loosen.   

However, the impact on seals and gaskets from using wrenches and other such tools is that they can compress and stress elastomeric gaskets too much, causing them to split or crack.  (To achieve the perfect sealing, 25% compression is the recommended amount of pressure to be used). 

In the case of Teflon or Garlock gaskets, fittings can also be easily damaged if excess over-torquing is used; rendering most gaskets unable to be reused with no guarantees for optimal sealing if these fittings require additional re-torquing throughout their usage. 

A solution to staying compliant 

If you believe you manway gasket to be non-compliant, or you’re concerned about NARs and your experiencing inconsistencies when it comes to how manway gaskets are installed, you need to start looking for long lasting and indeed reusable seals. 

Using a precision engineered gasket that incorporates a sealing bolt torque which can be maintained, as well as not being able to fall into manways, and where the installation is simplified, will ultimately help you to improve the safety of manway door seals and man lid door seals as well as keep you fully compliant. 

Using the Parker Hannifin Sure Torque Gasket is one great solution to provide you with all of the above and so much more. 

Eliminating all issues relating to compression set and creep due to its carefully designed compression control and stainless-steel inset.  Designed for universal use, the Parker gasket fits all nozzle and lid designs with ease. 

It is also reusable, maintains bolt torque, it doesn’t require bolt re-torquing, and it is a gasket that can’t fall into the manway. 

The Parker design is also one of the first to allow for a more simplified design approach allowing for increase speed in securement, without the worry of spills and leakages. 

The rubber mixing capability and seal numbers also ensure full traceability back to the raw materials used in the manufacturing process. 

This particular gasket provides a wide range of elastomers to work alongside and combat many of the sealing challenges faced by industries today. 

It is possible to achieve an effective and compliant seal with existing gaskets and Specialist Sealing Products has a range of gaskets available to suit a wide variety of industries and businesses. 

Selecting the right material is critical to ensure long term sealability; and with an increase in accountability for NARs as well as more inspections and expectations to use safer technologies, now is the time to check your manway gaskets are up to scratch. 

The costs of failing to have robust and reliable seals in place, far out way anything else.   

With the threat of large and often unlimited fines, working and using the right gaskets is about improving the safety of manways in all capacities and ensuring the best outcome for all parties.
