The LARSEN SUPPLY CO. INC. 11-1004 is a high-density PTFE thread seal tape designed for industrial and all-purpose pipe thread sealing applications. The tape measures 1 inch wide by 1429 inches long and comes in blue, making it easy to distinguish from standard white tape on the job. At 6 pounds per bulk pack, this is a high-volume roll suited for shops, service fleets, or contractors who go through thread tape regularly. PTFE thread tape reduces galling, lubricates threaded joints, and creates a leak-resistant seal on a wide range of pipe materials and fittings across plumbing, HVAC, and industrial service work.
This tape is rated for all-purpose use across a broad range of pipe materials including iron, brass, copper, aluminum, stainless steel, galvanized steel, polyethylene, polypropylene, PVC, CPVC, ABS, and fiberglass. It is well-suited for residential and commercial plumbing systems, HVAC refrigerant and water line connections, and general industrial piping. The bulk format is intended for high-volume use by licensed plumbers, pipefitters, HVAC technicians, and mechanical contractors who need a reliable supply on hand without frequent reordering.
Designed for use on iron, brass, copper, aluminum, stainless steel, galvanized steel, polyethylene, polypropylene, PVC, CPVC, ABS, and fiberglass threaded pipe and fittings across plumbing, HVAC, and industrial piping systems.
Thread seal tape is applied by licensed plumbers, pipefitters, and HVAC technicians during joint assembly. Always shut off the water supply or isolate the system before disassembling or assembling threaded connections. Wrap tape in the direction of the thread to prevent unraveling during assembly. Do not over-apply tape on fine threads, as excess material can restrict flow or cause fitting damage.
