- Polytetrafluoroethylene (PTFE): This fluoropolymer is known by the brand name Teflon and is known to assure the best chemical resistance and exceptionally little frictional resistance. It is the material of choice for several types of rotating seals used in the chemical, food, and pharmaceutical industries.

- Installation and maintenance are also relatively simple with rubber flange gaskets. They can be easily installed using standard tools and techniques, and their maintenance requirements are minimal. Regular inspection and replacement as needed can help ensure the continued effectiveness of the gaskets.
Many – too numerous to list, covering a vast range of designs, sizes, and materials suitable for a never-ending range of applications. Some designs conform to International Standards such as BS1399 and DIN 3760 for metric sizes and seal types, but the majority have been manufactured to suit particular applications – hence the enormous selection available. This blog is intended to assist in this selection and will consider seal type, materials, and sizes.

What is Oil Seal

oil seal 45 65 10. Its simple yet effective design allows for quick and hassle-free replacement, saving time and effort for maintenance personnel. This convenience factor makes it a popular choice among maintenance professionals looking for reliable sealing solutions.
The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.
Ensuring Proper Installation and Maintenance
Significance of Quality Seals in Automotive Applications:


First, an elastomer, most often nitrile, is vulcanised to a metal ring. This creates a stiffening effect that includes a specialised metal tension spring directly behind the sealing lip, keeping the oil seal firmly in place against the moving part.

We just discovered that one of the seals on our pumping system is leaking. Do you have any ideas as to what could have caused this, and can you offer some advice for selecting a good seal?
