Double bolt clamps are used to securely fasten two hoses or pipes together in a variety of applications, such as automotive, industrial, and plumbing. They consist of a band of metal with two bolts that can be tightened to create a strong seal.
   To use double bolt clamps, first, select the appropriate size clamp for the hoses or pipes you are connecting. Make sure the clamp is slightly larger than the diameter of the hoses or pipes to ensure a proper fit.
   Next, place the clamp around the hoses or pipes and position it in the desired location. The bolts should be on the opposite side of each other for even pressure distribution.
  Then, tighten the bolts using a wrench or socket wrench until the clamp is securely fastened. Be careful not to overtighten the bolts, as this could damage the hoses or pipes.
  Double bolt clamps are commonly used in high-pressure applications, so it is important to check the tightness of the clamp regularly to ensure a leak-free seal.
  Overall, double bolt clamps are a versatile and reliable solution for connecting hoses or pipes in various industries, providing a strong and secure seal that can withstand pressure and vibration.
