• 【Practical Functions】: When your car is in the maintenance process, the plug nuts can be used to temporarily block the oil pipe joints. Then oil leakage can be effectively avoided in the fuel system. Additionally, they can also prevent impurities into the system and damage to other parts of the system.
• 【Excellent Sealing】: The plug nuts are precisely processed to exact tolerances for trouble-free performance, ensuring a perfect match with threads of the tubing joints. Moreover, they also adopt flare design, which better fit tubing joints for good leak proof sealing. Thus there is no need to worry about oil leakage.
• 【Quality Material】: Made of tough aluminum, the plug nuts are equipped with excellent rust and corrosion resistance. And they can well withstand high pressure and high temperature, maintaining stability during a long period of use. Besides, their surfaces are anodized in black for great appearance and resistance to fading.
• 【Easy Installation】: You will receive two pieces of plug nuts, which are easy to install with the designs of hexagonal shape and 360 degree swivel. First, locate the tubing joint that needs to be plugged. Second, place the plug nut on the tubing joint. Finally, tighten the nut by turning it clockwise with the help of an adjustable wrench.
