Practical installation tips
- Prepare threads with a clean, dry surface before assembly. Use PTFE tape or an appropriate pipe joint compound on male threads, applied in the direction of tightening.
- Aim for a snug but not over-tightened fit to prevent galling or cross-threading. If you feel resistance, back off slightly and re-torque.
- Ensure mating fittings are compatible with MIP threads and within the nipple’s 230 psi and 400°F ratings for your application.
- After assembly, test for leaks with a gentle pressure test and inspect the galvanized surface for any nicks or abrasions that could compromise protection.
In short, the STZ Industries 2-1/2 in. MIP x 2-1/2 in. MIP Galvanized Steel Nipple delivers a robust, long-lasting solution for building secure, leak-free piping connections.
