The Smith-Cooper 3/4 in. FPT x 3/4 in. FPT Stainless Steel Union is built to simplify pipe connections where two 3/4" threaded runs meet. With a lead-free stainless steel body and two 3/4" female pipe thread (FPT) ends, this union provides a dependable, corrosion-resistant join for potable-water and light-industrial piping.
Why this union stands out
-
Lead-free stainless construction delivers peace of mind for drinking water systems and reduces corrosion risk in challenging environments.
-
Two identical 3/4" FPT ends make it straightforward to connect two compatible pipes or fittings with female threads, enabling clean, secure assemblies in tight spaces.
-
Retail-ready carded packaging supports quick selection on the shelf, while the durable stainless body resists rust, staining, and chemical exposure over time.
Practical applications and use cases
- Residential and commercial potable water lines where a quick, dependable union is needed to join 3/4" threaded sections.
- Heating and cooling loops, boiler feed systems, or radiant systems that demand corrosion-resistant connections.
- Repairs or retrofits where existing 3/4" FPT piping requires a simple, leak-tested joint without soldering or welding.
How to install for best results
- Ensure mating threads are clean and free of debris before assembly.
- Apply an appropriate pipe-thread sealant or PTFE tape compatible with metal threads to the male sides that will mate with these FPT ends.
- Hand-tighten the union, then snug with a wrench just enough to create a seal. Avoid over-tightening, which can damage threads or the fitting.
- After installation, perform a leak test by gradually pressurizing and inspecting for any seepage around the joints.
Designed for reliability in everyday piping tasks, the Smith-Cooper 3/4 in. FPT x 3/4 in. FPT Stainless Steel Union combines durable materials with sensible, serviceable design. It’s an ideal choice for professionals and DIY enthusiasts who value long-lasting performance, straightforward installation, and safer, lead-free construction for water systems.
