- In addition to preventing oil leaks, the spark plug O-ring also helps to maintain the proper air-fuel mixture inside the combustion chamber. If this mixture is disrupted, it can result in poor engine performance and reduced fuel efficiency. By keeping the seal tight, the O-ring ensures that the spark plug is able to ignite the air-fuel mixture at the right time, allowing the engine to run smoothly and efficiently.

synthetic rubber gasket.
This technique involves aligning the installation tool with the face of the shaft to precisely position the seal. Double-checking alignment after installation is essential to avoid future misalignment issues.
Bauerle and Bruhnke7 found that aeration reduces the effect of oil additives on fluoroelastomer properties. Some of their data is reproduced in Fig. 14.4,5 showing the effect of aeration of an SF-grade 5W30 oil on the retention of elongation of a VDF/HFP copolymer (FKM-E430), a VDF/HFP/TFE terpolymer (FKM-B600), and a VDF/PMVE/TFE fluoroelastomer (FKM-GFLT). The HFP-containing polymers show much better retention of properties with aeration.

In addition to the installation procedure, our specialists and suppliers would also like to draw your attention to some cases that occur around oil seals.
Super Helix Seal
Some distributors can be removed without separating the gears, and so the arm does not turn.
This is almost similar to that of ‘A’ type seal. But this has the metal case placed outside. When the housing is rough, temperature is high and working conditions are severe, this type is preferred
