Description

This High-Pressure Steel Adapter is engineered to connect a 3/8″ male pipe thread to a 1/4″ female pipe thread in a straight line. Rated for a heavy-duty 4,000 PSI, this forged carbon steel fitting features an oversized internal female thread on one end and a smaller external male thread on the other, making it an excellent choice for adapting mismatched connections in demanding fluid systems.

Key Specifications

• Connection Type A: 3/8″ FPT (Female Pipe Thread – Inner)

• Connection Type B: 1/4″ MPT (Male Pipe Thread – Outer)

• Material: High-Strength Forged Carbon Steel

• Pressure Rating: 4,000 PSI (Maximum Working Pressure)

• Design: Straight Hex Body Adapter

Product Highlights

• Oversized Female-to-Male Transition: Allows you to easily step up from a 1/4″ female port to a 3/8″ male line, or step down a 3/8″ male line to a 1/4″ female component without utilizing multiple bulky fittings.

• Extreme 4,000 PSI Capability: Forged from premium carbon steel to safely handle heavy-duty operational pressures, intense hydraulic spikes, and fluid water-hammer shocks without weeping or cracking.

• Wrench-Friendly Hex Body: Precision-machined with a solid external hex profile. This allows standard open-end wrenches, adjustable wrenches, or sockets to grip the adapter securely for maximum leverage during tightening.

• Vibration & Fatigue Resistant: High tensile strength ensures the tapered NPT threads resist stripping, shearing, or backing out under the constant, heavy vibrations of commercial engines and high-displacement pumps.

• Corrosion Protection: Finished with a durable zinc plating that shields the raw carbon steel from rust, moisture, and chemical exposure in rugged commercial wash and industrial environments.
