Note:

Pipe Fittings Hex Nipples Male NPT are high-pressure connectors used to join two female threaded pipes or fittings. They provide a strong, reliable seal for fluid and gas systems.

Executive Summary

A Pipe Fittings Hex Nipple Male NPT is a short threaded connector designed to join two female-threaded pipes or fittings. Male indicates that the threads are on the outside, while NPT (National Pipe Thread) is the standard tapered thread in North America that provides a tight, leak-resistant seal.

The hexagonal shape allows easy tightening with a wrench. In the oil and gas industry, hex nipples are commonly used to connect flow lines, instrumentation, valves, and pressure equipment, ensuring secure transfer of liquids and gases under high pressure and demanding conditions.

Detailed Description

The Hex Nipple Pipe Fitting with Male NPT threads is a precision component used to connect two female-threaded pipes or fittings in instrumentation and process control systems. The male tapered threads create a tight, leak-resistant seal when engaged with a corresponding female NPT connection, making it suitable for high-pressure and high-temperature applications commonly found in the oil and gas industry.

Manufactured from high-quality bar stock, the fitting provides strength and durability. Threads are capped and carefully packed to prevent damage during transport. The fitting is marked with the manufacturer’s name, size, material, and heat code for traceability. The design ensures proper thread engagement, reliable sealing, and smooth flow of fluids or gases.

These fittings meet or exceed ASME B1.20.1 standards for NPT threads and are rated according to ASME B31.3 for process piping, supporting safe and consistent operation in industrial environments. The male NPT design allows easy installation while maintaining a durable, leak-tight connection over the life of the system.
