Description

This Heavy-Duty 316 Stainless Steel Pipe Adapter (also referred to as a bushing or step-up expander) is engineered to connect a smaller 3/8″ female pipe threaded port to a larger 1/2″ male pipe threaded line. Machined from premium Grade 316 Stainless Steel, this fitting provides industry-leading resistance to pitting, chloride corrosion, and aggressive chemicals, making it ideal for high-consequence industrial, marine, and chemical processing environments.

Key Specifications

• Connection Type A: 3/8″ MNPT (Male National Pipe Thread)

• Connection Type B: 1/2″ FNPT (Female National Pipe Thread)

• Material: Grade 316 Stainless Steel (SS316)

• Design: Straight Hex Body Thread Expander / Adapter

• Pressure Rating: Typically rated between 3,000 to 6,000 PSI (dependent on wall thickness/manufacturing class, such as Schedule 150 or 3000# forged)

Product Highlights

• Premium 316 Stainless Steel Construction: Contains molybdenum, which provides significantly higher resistance to corrosion, pitting, and stress-cracking in harsh environments (such as saltwater, acids, and sanitizing chemicals) compared to standard 304 stainless steel or brass.

• Compact Thread Step-Up: Allows you to seamlessly transition and enlarge a piping run from a 3/8″ port to a 1/2″ line within an incredibly tight physical footprint.

• Heavy-Duty Hex Body: Precision-machined with a robust external hex nut shape in the center. This allows standard open-end wrenches, adjustable wrenches, or deep sockets to apply maximum torque for a gas-tight, leak-proof seal.

• Precision-Cut NPT Threads: Manufactured to strict tolerances to ensure deep thread engagement and a dependable, high-pressure metal-to-metal interference fit.
