- Jack and jack stands (if access to the underside is required)
• Super helix seal (seal with one-way two-step screw)
Installation techniques must be carefully selected and executed to ensure the seal functions correctly throughout its service life. Each technique addresses specific installation needs and ensures long-term reliablity.

ptfe oil seal. This makes them suitable for use in applications where other types of seals may be damaged by exposure to chemicals.
Polytetrafluoroethylene (PTFE, Teflon®)
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.
In addition to their sealing and durability properties, natural rubber gaskets also offer excellent resistance to a wide range of chemicals, including oils, solvents, and acids
. This makes them suitable for use in harsh industrial environments where exposure to corrosive substances is common.natural rubber gasket

Select the correct oil seal size
This is one of the frequent reasons for oil seal failure, and this is majorly because of the volatility of any of the elastomer’s constituents. These causative constituents may be part of the elastomer formulation, or gases that got entrapped in the elastomer during the molding process. The deceiving fact about this failure is that sometimes the oil seal won’t show any visual sign of out-gassing, however, sometimes when the out-gassing is extreme, they shrink.
Thoroughly clean the sleeve at the back of the pulley, and look for any roughness on it where it touches the seal. If necessary, smooth it with fine wet-and-dry abrasive paper.
In conclusion, oil seals play a critical role in high-pressure systems by preventing leaks and maintaining the integrity of the machinery. With proper design, materials, and maintenance, high-pressure oil seals can withstand the extreme pressures and harsh conditions commonly found in industrial settings. By investing in quality seals and regular maintenance, operators can ensure the reliability and efficiency of their high-pressure systems for years to come.


For the housing stop installation technique, set the seal depth flush with the bore’s interior shoulder. This technique ensures that the seal is perfectly aligned with internal housing components. A depth gauge can be crucial here to confirm that the seal is positioned correctly.
PTFE is special in that a pre-tensioned spring is not required. This is because the material returns to its original shape when heated, also known as the shape-memory polymers (SMPs) effect. These oil seals are also supplied as integrated parts, where it only needs to be installed as one component.
