- Mechanical face seals, also known as floating-face or heavy-duty face-type seals, are typically used in more demanding applications where high pressures and extreme temperatures are present. They consist of two metal rings with flat faces that are held together by springs and form a dynamic seal between them.
Note how the mounting nuts or bolts are fitted, then undo them. Have ready some wooden wedges to use as supports, and a strong helper to hold the engine steady.

Oil seals can show good sealing performance in combination with properly designed shafts and housings.
There are several materials used to manufacture oil seals. They are discussed below.
Oil Seals, also known as fluid seals, grease seals, dirt seals, shaft seals, or lip seals, help to seal the gap between static and moving components in machinery and equipment. Oil Seals used in rotating applications are known as rotary seals.
EPDM
Pour-point depressants: This additive has nothing to do the actual pouring of your oil. In fact, pour-point depressants help prevent the wax particles in the oil from hardening in cold conditions. As a result, the motor oil flows freely even in low, cold temperatures and the engine doesn’t need to work any harder to pump it.
In choosing the right oil seal type for your application, it is essential to assess factors such as speed, temperature range, pressure levels, chemical compatibility, shaft material, and installation space limitations. By considering these factors carefully, you can ensure that you select an oil seal that will provide optimal performance and longevity in your specific application.


Viton (Fluorocarbon)
Box: If a BX appears at the end of the part number, that oil seal will be in a box.
Synthetic blend oil offers the best of both worlds. It has many of the characteristics of full synthetic oil, but at a much lower price. This type of oil is a mixture of synthetic and conventional base oils, plus some additives, for extra resistance to oxidation and excellent low-temperature properties. Synthetic blends make it easy for drivers to make the switch from conventional to synthetic oil, which is why this type of oil is becoming increasingly popular among today’s savviest drivers. It’s also a great middle ground for drivers who want the added protection and performance of a synthetic oil, but might not be ready to foot the bill for a total switch to full synthetic oil.
