Key Specifications

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

• Material: High-Strength Forged Carbon Steel

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

Product Highlights

• Robust Port Termination: Designed to safely block off dead-ends, unused manifold outlets, or bypass ports without altering your existing plumbing structure.

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

• Wrench-Friendly Hex Head: Precision-machined with a solid external hex head profile. This allows standard open-end wrenches, adjustable wrenches, or sockets to grip the plug securely for maximum leverage and a tight seal during installation.

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

• 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.
