1/2 inch x Close Stainless Steel Nipple

1/2" x Close Stainless Steel Nipple – Threaded Fitting for High-Integrity System Connections

The 1/2" x Close Stainless Steel Nipple is a precision-machined pipe fitting used to connect components within pressurized or corrosive piping systems. Constructed from stainless steel for superior resistance to oxidation and chemical degradation, this close nipple is suitable for a variety of industrial, mechanical, and plumbing applications where compact connections are required.

Its close-length profile eliminates unnecessary spacing between adjacent fittings or valves, reducing system footprint while maintaining full thread engagement. Manufactured to applicable ANSI/ASME standards, it provides a secure and corrosion-resistant threaded connection in demanding environments.

Engineering and Material Attributes

• ✅ Stainless Steel Fabrication – Provides structural strength and resistance to pitting, rust, and chemical exposure in aggressive environments.
• ✅ Close Nipple Configuration – Minimizes the distance between connected fittings, allowing installation in limited-clearance locations.
• ✅ Thread Type: NPT – Male National Pipe Threads conform to ANSI B1.20.1 for secure, leak-resistant engagement with female-threaded components.
• ✅ Precision Cut Threads – Reduces the risk of galling and ensures consistent torque values across multiple installations.
• ✅ System Compatibility – Commonly used in potable water, gas, air, oil, and hydronic piping systems; appropriate for both horizontal and vertical installations.

Specifications

Installation Guidelines

Install using appropriate thread sealant or PTFE tape rated for the media type (gas, water, steam, etc.). Ensure full thread engagement without over-torquing to preserve thread integrity. For high-pressure or high-temperature applications, verify that the nipple material and wall thickness meet all project design requirements and applicable codes.

Application Scenarios

This stainless steel close nipple is routinely used in mechanical rooms, pump and valve manifolds, industrial skids, commercial kitchens, process piping layouts, and other applications where compact, corrosion-resistant threaded connections are needed.

The 1/2" x Close Stainless Steel Nipple delivers long-term performance in environments requiring strength, corrosion resistance, and dimensional precision. Specified for systems where compact design and leak-resistant threaded connections are essential.
