Description

This 3/8″ FPT x 3/8″ MPT Steel Adapter is a rugged, straight extension fitting (often referred to as a gauge adapter or gender changer) built for high-pressure industrial plumbing. Rated for a robust 4,000 PSI, this carbon steel component is designed to handle the intense pressures, fluid shocks, and heavy vibrations common in commercial pressure washing and hydraulic systems.

• Connection Type B: 3/8″ MPT (Male Pipe Thread – Outer)

• Material: High-Strength Carbon Steel

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

• Design: Straight Hex Adapter / Extension

Product Highlights

• True-Match 3/8″ Flow: Matching 3/8″ nominal sizes ensure a seamless, completely unrestricted fluid pathway, preventing pressure drops or turbulence in your high-pressure lines.

• 4,000 PSI Capability: Forged from high-grade carbon steel to safely handle high-pressure discharge water or hydraulic fluid, offering a vastly superior safety margin compared to standard brass.

• Component Extension & Protection: Provides just enough physical clearance to mount accessories like unloader valves, gauges, or quick couplers away from tight pump manifolds, making maintenance simple.

• Vibration & Stress Resistant: High tensile strength ensures the fitting resists cracking, shearing, or thread stripping caused by the constant shaking of gas-powered engines and high-displacement pumps.

• Corrosion Protection: Plated with a durable zinc coating that shields the raw steel from rust, moisture, and chemical exposure in harsh, everyday wash environments.

• Wrench-Friendly Hex Design: Features an integrated solid hex nut body, allowing for a secure grip with standard wrenches for high-torque tightening.
