1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.

  • d. Fluorocarbon Rubber (FKM) – is widely known under the Chemours (formerly Dupont™) trade name of Viton® and offers the best resistance to chemicals and superior performance to high temperatures.
  • One of the main functions of the valve cover gasket assembly is to prevent oil leaks and keep the engine running smoothly. Oil leaks can be a significant issue as they can cause damage to the engine components and lead to decreased performance. The valve cover gasket assembly acts as a barrier between the oil in the engine and the outside environment, ensuring that the oil stays where it belongs.
  • Crafted from durable elastomers, the small rubber gasket is designed to fill the gap between two surfaces, providing an airtight and watertight seal. Its elasticity allows it to conform to irregularities in mating surfaces, ensuring a continuous barrier against fluid or gaseous leakage. In essence, the small rubber gasket is the guard that stands sentinel at the threshold of potential failure, preventing catastrophic consequences such as oil spills or refrigerant loss.

  • The effectiveness of a spark plug is determined by its heat range, quality of construction, and electrode material. A spark plug with the correct heat range ensures optimal performance and fuel efficiency, while a high-quality material like platinum or iridium increases durability and resistance to wear.
  • Check for flatness with a straight-edge laid across diagonally. Then measure gaps with a feeler gauge.

  • These types are made with a metal outer case and a PTFE lip. They are suitable for a wide range of temperatures from -90 °C to +260 °C.These lip seals can also be used for higher pressures of up to 10 bar (special types up to 25 bar) and rotational speeds of up to 40-45 m/s. Certain grades of PTFE are suitable for use in pharmaceutical and food applications. One important point is that PTFE lip seals do require a shaft with a harder, smoother finish.

  • Energy savings

  • No code: without minor lip

  • 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.

  • There are several signs that indicate a faulty spark plug coil, such as a rough idle, difficulty starting the engine, decreased fuel efficiency, and engine misfires

  • The 7mm spark plug wire is a crucial element in the ignition system of combustion engines. It carries the high voltage from the ignition coil to the spark plug, bridging a gap that is both electrical and metaphorical. Without these wires, the precise timing of ignition that modern engines demand would not be achievable, leading to poor performance, increased fuel consumption, and elevated emissions.
  • Silicone Gasket Sheets A Versatile Solution for Sealing Applications
  • A valve cover gasket is a crucial component of an internal combustion engine, as it seals the valve cover to the cylinder head, preventing oil leaks and ensuring the proper functioning of the engine. The 318 valve cover gasket is specifically designed for the Dodge 318 engine, which is a popular choice for many vehicles due to its reliable performance and durability.
