Why this hex bushing makes sense for your project
If you’re upgrading an old line, reconfiguring a plant floor, or wiring a new irrigation layout, this STZ Industries bushing provides a dependable transition between sizes without bulky adapters. The combination of MIP to FIP threading, a hex gripping surface, and a tough black malleable iron body translates to straightforward installation, reduced risk of leaks, and fewer components to manage on the job.
Ideal use cases
- Residential and commercial potable water systems where a 1-1/4" to 1/2" reduction is needed
- Irrigation and landscape plumbing projects requiring robust, corrosion-resistant fittings
- HVAC and light-industrial piping where dependable NPT connections are essential
- Repairs and retrofits in tight spaces thanks to the hex shape for improved tool access
Installation tips
For best results, ensure threads are clean and free of damage before application. Use an appropriate pipe thread sealant or PTFE tape rated for metal threads on the male side, and tighten with standard wrenches using a two-wrench technique to prevent cross-threading. After installation, pressurize the system gradually and inspect for leaks, re-tightening as required.
