Pipe, hose, and tubing move materials such as air, water, gasoline, and chemicals from one place to another. Pipe is rigid, hose is flexible, and tubing can be either rigid or flexible. Fittings connect pipe, hose, and tube to tools and equipment or join sections of pipe, hose, and tube together in a system. Fitting clamps secure tube and hose connections in fluid and air transport systems to ensure a tight fit and prevent leaks. Routing clamps, supports, and hangers hold, route, and suspend lines of tube or pipe in general plumbing, fire-sprinkler, and HVAC applications. Insulation, jacketing, and coatings insulate tubing and pipe against thermal loss and protect from impact and exposure to harsh conditions. Blocking plugs provide a seal inside or at the end of pipe systems to block flow and allow for pressure testing and maintenance. Repair clamps and kits seal cracks, holes, and punctures in damaged sections of tube or pipe to prevent leaks.
