Description

When you’re plumbing a hydraulic system, air compressor line, or fuel tank setup, you need fittings that won’t let you down. This 4-inch black iron nipple gives you the reliable connection between two female fittings, whether you’re extending a line or bridging components that need a little extra space between them.

What You’re Getting

Heavy-duty black iron construction that handles high pressures without breaking a sweat
Standard 1/4-inch male NPT threads on both ends for secure, leak-free connections
4-inch length gives you flexibility for spacing components or clearing obstacles
Black oxide coating resists corrosion better than plain steel

Built for Real Farm Work

This nipple works great in hydraulic systems, air lines, fuel systems, and anywhere you need a solid threaded connection. The 1/4-inch size is perfect for smaller hydraulic circuits, gauge lines, or pilot systems on larger equipment. You’ll find these handy for everything from connecting pressure gauges to plumbing auxiliary hydraulic circuits.

Made to Last

Black iron fittings are the standard in industrial and agricultural applications because they can handle the pressure and abuse that comes with farm work. The black oxide finish gives you better corrosion resistance than bare steel, so this nipple will keep doing its job even in damp conditions.

Installation Notes

Thread both ends into your fittings hand-tight, then use a wrench to snug them up. Don’t overtighten—the tapered NPT threads seal themselves as you tighten. A little pipe dope or thread sealer helps ensure a leak-free connection that’ll stay put through vibration and temperature changes.
