1/4 inch x 3 inch Stainless Steel Nipple

1/4" x 3" Stainless Steel Nipple – Threaded Pipe Segment for Corrosion-Resistant Applications

The 1/4" x 3" Stainless Steel Nipple is a precision-threaded fitting used to connect two female-threaded components in mechanical, plumbing, or industrial fluid systems. Manufactured from corrosion-resistant stainless steel, this nipple is suitable for environments requiring chemical resistance, sanitary compatibility, or long service life under variable temperature and pressure conditions.

Designed for use in non-potable and potable water systems, heating loops, compressed air lines, and process piping, this component delivers mechanical strength and dimensional accuracy. Its 3-inch length supports system layout flexibility where short offsets are required between components or in confined mechanical assemblies.

Key Characteristics

• ✅ Corrosion Resistance: Stainless steel construction (typically 304 or 316 grade) resists oxidation and chemical attack in wet or aggressive environments.
• ✅ Threaded NPT Ends: National Pipe Tapered (NPT) threads ensure a tight mechanical seal when properly installed with thread sealant or PTFE tape.
• ✅ Dimensional Tolerance: Manufactured to ASTM A733 specifications for pipe nipples, ensuring compatibility with standard pipe fittings and components.
• ✅ Pressure-Rated: Suitable for use in pressure-bearing systems within the limits of the material grade and wall schedule.
• ✅ Lead-Free Compliance: Conforms to NSF/ANSI 372 where applicable for potable water contact in lead-restricted systems.

Technical Specifications

• Nominal Diameter: 1/4 inch
• Length: 3 inches
• Material: Stainless Steel (typically 304 or 316, depending on specification)
• Connection Type: NPT Male x Male
• Standards: Threads per ASME B1.20.1; pipe nipple dimensions per ASTM A733

Installation Notes

Apply a suitable thread sealant or PTFE tape to both male threads before assembly. Use two pipe wrenches to prevent thread galling and ensure proper torque during installation. Confirm compatibility with adjacent components regarding pressure rating, material type, and media exposure.

Applications

This fitting is used in stainless steel piping systems across plumbing, HVAC, compressed air, chemical process, and food-grade installations. It is particularly effective in systems requiring durability under frequent thermal cycling, vibration, or exposure to corrosive agents.

Material Insight

Stainless steel nipples provide superior longevity and reduced maintenance in applications where traditional carbon steel or brass fittings would corrode or degrade over time. Proper material selection (e.g., 316 stainless) enhances performance in high-chloride or acidic conditions.

The 1/4" x 3" Stainless Steel Nipple is a precision-machined component engineered for use in demanding environments requiring corrosion resistance, mechanical integrity, and consistent thread engagement.
