3/8 inch x 1/4 inch Stainless Steel Hex Head Bushing Male x Female

3/8 inch x 1/4 inch Stainless Steel Hex Head Bushing – NPT Threaded Reduction for High-Durability Applications

Engineered for dependable pipe size transition in threaded systems, the 3/8 inch x 1/4 inch Stainless Steel Hex Head Bushing provides a corrosion-resistant and pressure-rated connection. Fabricated from Type 304 or 316 stainless steel, this hex bushing is suitable for both mechanical and industrial applications involving air, gas, water, and steam lines.

Product Features

• Connection Type: 3/8 inch Male NPT x 1/4 inch Female NPT – compliant with ANSI/ASME B1.20.1 tapered thread specifications
• Material: 304 or 316 Stainless Steel, providing excellent resistance to corrosion, rust, and chemical exposure
• Hex Head Design: Allows for easy torque application during installation using standard hand tools
• Operating Conditions: Typical pressure ratings up to 150 psi for steam and 1000 psi for cold water/oil/gas (WOG), depending on system parameters
• Temperature Range: Suitable for service temperatures from -20°F to over 400°F, depending on gasket/sealant compatibility

Installation Considerations

Hex bushings should be installed using an approved thread sealant or PTFE tape to ensure a pressure-tight joint. Over-tightening can result in thread galling or mechanical damage—tighten only to manufacturer-recommended torque specifications. Not intended for use in potable water systems unless manufactured from certified lead-free stainless steel per NSF/ANSI 61 or 372 standards.

Application Areas

Commonly used in hydraulic, pneumatic, and HVAC systems, this bushing allows for safe and space-efficient reductions in NPT threaded piping. Applicable in OEM equipment, fuel supply manifolds, process piping, and other fluid or gas conveyance lines in both commercial and industrial environments.

Standards & Compliance

• Manufactured to ASTM A182 (for forged stainless steel fittings)
• Threading per ANSI/ASME B1.20.1
• Material conforms to ASTM A276 (round bar, cold-finished stainless)

Did You Know?

Stainless steel bushings offer a significant lifespan advantage over galvanized or brass components, especially in high-humidity or chemically aggressive environments. Their low carbon content also enhances weldability and corrosion resistance at the threads.

For plumbing systems that demand durability and code-compliant performance, the 3/8 inch x 1/4 inch Stainless Steel Hex Head Bushing delivers consistent results under pressure. Integrate this fitting into your next build for a long-lasting, high-integrity threaded connection.
