A PVC Spacer is a type of component used in plumbing and piping systems to create a specified gap or separation between two surfaces. PVC spacers are typically made of PVC (polyvinyl chloride), a type of plastic that is durable, resistant to chemicals and corrosion, and relatively inexpensive. PVC Spacer is used in a variety of applications, such as plumbing, HVAC, and electrical systems, to separate pipes, conduits, or other components and prevent them from rubbing against each other or other surfaces, which can cause damage or other issues.
