Description

This 3/8″ MPT Steel Allen Head Plug (also known as a hex socket pipe plug) is built to seal off unused ports in demanding industrial systems. Rated for a robust 4,000 PSI, this carbon steel plug installs flush with the surface of the manifold, protecting the port from external impacts while delivering an elite, leak-proof seal.

Key Specifications

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

• Drive Style: Internal Hex / Allen Head Socket

• Material: High-Strength Carbon Steel

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

• Profile: Countersunk / Flush Mount

Product Highlights

• Low-Profile, Flush Design: The internal hex drive allows the plug to sit completely flat or recessed within the port. This eliminates protruding hex heads that can snag hoses, damage equipment, or break off during operation.

• 4,000 PSI Capability: Forged from high-grade carbon steel to safely handle severe hydraulic spikes, fluid shocks, and intense operational pressures without cracking or weeping.

• High-Torque Drive Socket: The precision-machined internal hex socket resists stripping and slipping, allowing you to apply maximum torque with an Allen wrench for a permanent, high-pressure seal.

• Vibration & Stress Resistant: High tensile strength ensures the threads resist loosening or stripping under the heavy, constant vibrations of commercial gas engines and high-displacement pumps.

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