Smith-Cooper 1-1/4" FPT x 1-1/4" FPT Stainless Steel Cap is a durable, lead-free closure designed for 1-1/4" pipe threads on both ends. Built from corrosion-resistant stainless steel, this cap seals off two male-threaded lines, making it ideal for maintenance, testing, and temporary shutdowns in demanding environments.
With stainless steel construction, it stands up to humidity, chemicals, and varying temperatures without warping or leaking. The dual female-thread design (FPT x FPT) ensures a secure fit on compatible male-threaded components, delivering dependable closures in industrial, commercial, or residential piping projects.
Typical applications include shutting off two lines during service, capping off test ports during pressure testing, or protecting exposed pipe ends during fabrication. It's particularly well-suited for potable-water systems where lead-free materials are a priority, as well as for HVAC, irrigation, and chemical processing lines where durability matters.
