Stainless Steel Hex Nipple – 1/4 in. MNPT (IHN-4N)

The IHN-4N is a 1/4" Male NPT hex nipple built from 316 stainless steel to meet the demands of high-pressure, high-purity, and corrosive fluid systems. Precision-machined for clean, consistent thread engagement, it ensures leak-tight performance even under extreme pressure and thermal cycling.

Its compact hex-body design allows for easy tightening using standard wrenches, making it ideal for tight spaces or field installations. Rated to 8000 PSIG, this nipple is commonly used in fuel systems, pressure instrumentation panels, chemical injection skids, and sanitary stainless steel assemblies.

Fully compatible with ANSI B1.20.1 threads and Swagelok® style piping systems, the IHN-4N provides the durability and reliability needed for critical process applications.

Key Benefits
