Meet the Smith-Cooper 1-1/2 in FPT x 1-1/2 in FPT Stainless Steel Cap — a rugged, lead-free solution engineered to seal 1-1/2" pipe threads on both ends. Crafted from durable stainless steel, this cap stands up to demanding environments where reliability and longevity matter for plumbing, HVAC, and industrial piping projects.
Why this cap stands out
-
Lead-free stainless steel: Safety and durability in one corrosion-resistant package, ideal for a wide range of applications.
-
Dual 1-1/2" FPT connections: Both ends feature female pipe threads, allowing you to cap two mating lines or seal a double-ended run with a single part.
-
300 psi maximum pressure: Provides a practical, high-strength solution for many piping systems encountered in professional settings.
-
Bagged packaging: Protected during shipping and easy to stock in tool rooms, supply warehouses, or on-site carts.
Ideal use cases
- Temporary closures during construction, testing, or system maintenance for 1-1/2" piping runs
- Sealing off two ports on manifolds or equipment where both ends require dependable closure
- Field retrofits and installations where a durable metal cap is preferred over plastic alternatives
Installation tips
- Ensure threads are clean and free of debris before installation
- Use an appropriate thread sealant or PTFE tape rated for stainless steel to improve seal integrity
- Thread by hand until snug, then tighten with the correct wrench—avoid overtightening to prevent galling
