Furthermore, fiberglass tanks are relatively lightweight compared to their steel counterparts, making them easier to transport, install, and maintain. This can result in significant cost savings for businesses in terms of labor, equipment, and maintenance expenses

What are Oil Seals and the different types?
Another critical factor to consider is the type of seal most suitable for particular machinery. When selecting your mechanical sealing solution, assess your machine’s shaft speed, temperature, pressure, environment, and the medium coming into contact with the seal during an operation. These factors help determine the color, size, sealing element, lip material to choose from, and if it can be sealed out or sealed in.
These new oil seals can also be equipped with a shaft rotation sensor.


made of a yieldable resilient material having flat sealing faces and comprising two ring portions connected together by an annular portion substantially v-shaped in cross-section which may yield or expand as the mounting requires.
Oil leak: the most frequent failure of the oil seal

Of course, all rubber materials and seals will provide a range of benefits; however, you will need to consider chemical compatibility, sufficient temperature ranges, pressure ranges, and more.
If you follow the above instructions, the oil seals should work properly. Also watch the video below for an example of the installation process.
Silicone rubber (VMQ)
Some aspects to consider when selecting this component are:
There is a British Standard laid down for the control of synthetic rubbers. BS 3574 (1989) helps to determine shelf life – for instance, Nitrile (NBR) and Polyacrylic (ACM) are Group ‘B’ rubbers and have a 7-year life, whilst Silicone (VMQ) and Fluoroelastomers (Viton®) are Group ‘C’ rubbers and have a 10-year shelf life. PTFE and Leather do not come into this category but like the others should be kept in the original packing for as long as possible away from direct light, dust, and humidity. Ozone, which can also be produced by battery-driven forklift trucks has a very bad effect on synthetic rubbers. Finally, protect the sealing lip – DO NOT hang the seals on nails, wire etc.
