STZ Industries 2-1/2 in. MIP each X 2-1/2 in. D MIP Black Steel 6 in. L Nipple

Meet a rugged, dependable connector built to keep your piping systems leak-free under pressure. The STZ Industries 2-1/2 in MIP x 2-1/2 in MIP Black Steel Nipple, 6 in long, is designed for sturdy, right-on-fit joins between two female-threaded components. With a bold black finish and solid steel construction, this nipple is ready for demanding environments in both residential and commercial installations.

Why this nipple stands out

• Bidirectional MIP on both ends: Two 2-1/2 in male pipe thread (MIP) connections make it simple to bridge gaps or extend runs with complementary fittings.
• 6 inch length: Provides flexibility for routing piping around tight spaces or aligning components precisely where a longer or shorter piece would fail.
• Lead-free material: Peace of mind for safer installations and compliant use in projects with stringent material requirements.
• Industrial-grade durability: Steel core with a durable black finish resists corrosion and stands up to everyday shop and jobsite wear.
• Broad compatibility: Ideal for water, air, and mechanical piping applications that use NPT/MIP threading at a 2-1/2 in nominal size.
• Reliable performance under stress: Rated up to 230 psi and 400°F, giving you confidence in both high-pressure and elevated-temperature environments.
• Convenient packaging: Bagged packaging helps protect threads from damage and keeps components clean during storage and transport.

Who needs this 2-1/2 in MIP x 2-1/2 in MIP nipple?

• Professional plumbers, HVAC technicians, and equipment installers who require robust, ready-to-use pipe nipples for frequent fittings and repairs.
• DIY enthusiasts tackling home improvement projects where reliable MIP connections are essential for water, heating, or air systems.
• Contractors building or extending piping runs in tight spaces where a 6-inch piece with both ends threaded is the perfect fit.

Practical use cases

• Connecting two female-threaded adapters or fittings in a water service line, radiant heating loop, or irrigation feed, while maintaining a solid seal.
• Spanning a small gap in a mechanical cabinet where the pipe layout requires a precisely 6-inch connector with MIP threads on both ends.
• Repairing a damaged section of pipe run by replacing a shorter segment with this 6-inch nipple to restore flow and integrity quickly.

How to install

• Ensure both mating threads are clean and undamaged. Use a compatible pipe thread sealant or PTFE tape on the male threads for a tight seal.
• Hand-tighten first, then snug with a pipe wrench. Avoid over-tightening to protect threads and prevent leaks.
• Verify the compatibility of your fittings (NPT/MIP) and ensure the nominal size matches (2-1/2 in) to avoid cross-threading or poor seating.
