3/4 inch x 5 inch Stainless Steel Nipple

3/4" x 5" Stainless Steel Pipe Nipple – Threaded Schedule 40 Connector

The 3/4" x 5" Stainless Steel Nipple is a precision-machined pipe section with NPT (National Pipe Thread) male threads on both ends, designed for use in pressurized piping systems. Manufactured from corrosion-resistant stainless steel, this component serves as a rigid extension for joining compatible threaded pipe, valves, or fittings in potable water, compressed air, oil, and non-hazardous chemical systems.

Conforming to ASTM A312 and ASME B1.20.1 standards, this nipple is commonly used in both commercial and industrial applications requiring durability and resistance to corrosive environments. Its uniform wall thickness and clean threading ensure system compatibility and leak-free integration.

Product Features

• ✅ Material: 304 or 316 Stainless Steel (varies by application), offering high corrosion resistance and tensile strength.
• ✅ Thread Type: NPT (tapered male threads) per ASME B1.20.1, for tight mechanical seal with compatible female-threaded fittings.
• ✅ Wall Thickness: Schedule 40, suitable for use in moderate-pressure systems.
• ✅ Length: 5 inches overall, end-to-end dimension including threaded sections.
• ✅ Nominal Size: 3/4 inch IPS (Iron Pipe Size).

Installation Guidelines

Installers should use an approved pipe thread sealant or PTFE tape on male threads to ensure leak-free operation. Thread engagement must be aligned and torqued per specification to avoid galling. For potable water systems, only NSF-certified sealants should be used. Wrenches should be applied on wrench flats or close to the threads to prevent excessive stress on adjacent components.

Application Use Cases

This nipple is used in systems requiring corrosion resistance, such as domestic and commercial water distribution, food-grade fluid lines, compressed gas setups, and marine environments. It is commonly installed between valves, tees, or unions when spacing and alignment must be precisely maintained in high-moisture or chemically reactive locations.

Technical Note

Stainless steel pipe nipples offer long service life in environments where galvanized or black steel would deteriorate. Type 316 stainless steel is preferred in coastal or high-chloride areas due to increased pitting resistance, while 304 is sufficient for most indoor and freshwater systems.
