- Regular maintenance and timely replacement of spark plugs are necessary to ensure optimal engine performance. Worn or dirty spark plugs can lead to misfires, reduced fuel efficiency, and even engine damage. It's recommended to follow the manufacturer's guidelines for spark plug replacement intervals, which typically range from 30,000 to 100,000 miles depending on the type of plug and driving conditions.
: prevents particles from reaching the sealing lip.
By far, nitrile is the most popularly used, but buyers who need seals for applications involving high-speed shaft rotation increased interest. Viton is another alternative for silicone and poly-acrylic because it’s more resistant to harmful chemicals and abrasion and works better in higher temperatures.
(3) The oil seal with general pressure has poor pressure bearing capacity, and the oil seal will deform when the pressure is too large. In the case of excessive pressure, a pressure-resistant bearing ring or a reinforced pressure-resistant oil seal should be used.
