• Premium Material: This automotive sealing plug is made of rubber material. Rubber maintains its shape and elasticity, resisting softening and loss of sealing capability. The material's high elasticity is key to its expansion function. When inserted into an oil hole, it gently expands to fill microscopic gaps in the hole walls, forming a tight, leak-proof seal.
• Universal Size: This automotive sealing plug is suitable for hole sizes ranging from 19mm to 38mm. The overall height of the sealing plug is 1.42 inches, with a mid-section height of 0.79 inches. It offers versatile applications across various liquid and gas systems in different vehicles, such as hydraulic systems and cooling systems.
• Convenient to Use: This automotive oil seal features precise dimensions and is easy to install. First, remove the old oil seal and clean the area with a cloth to ensure the rubber adheres firmly. Next, insert the new oil seal. Finally, simply tighten the hex nut to complete the installation.
• Practical Function: This automotive sealing oil plug fills microscopic gaps to form a 360° leak-proof barrier. This prevents oil from seeping onto the ground and water from entering the system. Additionally, the rubber's elasticity acts as a shock absorber. It absorbs road vibrations and engine vibrations, ensuring the plug remains securely fastened.
• Package Include: Our product packaging is boxed, with dimensions of 6.46 x 4.68 x 2.24 inches. The package includes 3 3/4''oil seals, 3 7/8'' oil seals, 2 1''oil seals, 2 1-1/8''oil seals, 2 1-1/4''oil seals, and 2 1-3/8''oil seals. This set provides ample quantity for daily use and replacement.
