Pipe, Hose, Tube & Fittings
Pipe, hose, and tubing convey materials like air, water, and chemicals. Pipe is rigid, hose is flexible, and tubing can be either. Fittings connect them, securing tight fits to prevent leaks. Clamps, supports, and hangers organize and suspend lines in plumbing and HVAC systems. Insulation and coatings protect against thermal loss and harsh conditions. Blocking plugs seal pipe ends for pressure testing, while repair clamps prevent leaks in damaged sections.
