Description

This High-Pressure Steel Reducing Hex Coupler (commonly referred to as a reducing socket) is engineered to connect two different sizes of male pipe threaded lines or fittings in a straight line. Rated for a heavy-duty 4,000 PSI, this forged carbon steel fitting safely transitions a 3/8″ MPT line down to a 1/4″ MPT line, providing an incredibly strong, leak-proof connection for demanding fluid systems.

Key Specifications

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

• Connection Type B: 1/4″ FPT (Female Pipe Thread)

• Material: High-Strength Forged Carbon Steel

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

• Design: Straight Hex Body Reducing Coupling

Product Highlights

• Inline Size Reduction: Integrates a 3/8″ to 1/4″ female thread transition into a single compact coupling, eliminating the need for an extra bushing and reducing potential leak paths in your plumbing network.

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

• 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.

• Vibration & Fatigue Resistant: High tensile strength ensures the internal 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.
