Why choose this STZ plug? The combination of malleable iron’s strength and ductility with a durable black finish delivers a plug that resists galling and provides a reliable seal under load. With a lead-free composition and straightforward MIP threading, it offers a practical, code-conscious choice for professional plumbers and facility managers alike.
Installation tips: Ensure threads are clean and dry. Apply an appropriate pipe thread sealant or PTFE tape approved for pipe threads, then thread the plug into the mating MIP connection using a wrench. Tighten to a snug seal—avoid over-tightening to prevent thread damage. After installation, check for leaks under pressurized conditions and re-tighten if necessary within recommended torque ranges.
