Another benefit of self-drilling screws is their versatility
- Screw Type Select the correct drive type (like Phillips, hex, or square) to match your tools and facilitate easier installation.
These oil seals are created from a low-temperature tolerant compound. Benefits include:
They are generally utilised for the following purposes:
On most cars you need to remove several parts to get at the seal.
Helix Seal
Outstanding resistance to mineral oils, aliphatic and aromatic hydrocarbons, as well as CHCs, concentrated and diluted acids, and weak alkalis. Excellent resistance to high temperatures (up to 200 °C) and a low temperature resistance down to -40 °C depending on the type used as well as good mechanical attributes and an exceptionally good ageing resistance make FPM a cut well above the usual synthesis natural rubbers.
To install an oil seal properly, the shaft must be undamaged. This is so the oil seal can do its job properly on the one hand, and to prevent it from being damaged during fitting on the other. In addition, it is very important to lubricate the shaft, the sealing lip and the bore with plenty of grease. This will allow the oil seal to slide more easily over the shaft and prevent dry running after the first rotation. The oil seal may also come into contact with the keyway, thread or other grooves when sliding over the shaft. By taping or covering the shaft at the location of these irregularities with oil-soaked paper, the oil seal can be mounted without damage to the sealing lip.

Regular inspection and replacement of oil seals are also necessary to prevent leakage and maintain the efficiency of the machinery. Over time, oil seals can wear out due to constant friction and exposure to harsh conditions, leading to leaks and potential damage to the equipment. By monitoring the condition of oil seals and replacing them as needed, operators can prevent costly downtime and repairs.
No matter the PTFE machining techniques and other processes used in making mechanical parts, they tend to fail due to some reasons. The same thing applies to oil seals. When they are exposed to some factors, they fail. The factors are stated below alongside the solutions.
Spark plug wires, also known as ignition wires or high-tension leads, are crucial components in the ignition system of internal combustion engines. These wires are responsible for transmitting the high-voltage electrical current from the ignition coil to the spark plugs, initiating the combustion process within the engine cylinders. High-quality spark plug wires are essential for ensuring efficient ignition, optimal engine performance, and reduced emissions, making them a critical component in the overall efficiency and environmental impact of the vehicle.
If the seal is being fitted to original equipment you may have some influence over the shaft and housing bore finish, but if you are replacing a worn seal you still need to take into account the condition of these 2 essential parts. Check for sharp edges and burrs – particularly on the shaft and housing chamfers or you could ruin the seal before you start up. If the shaft is too worn consider using an M Barnwell Services Shaft Repair Kit.
