1/4" Autoclave Male x 1/2" NPT Female Medium Pressure (MP) Hex Nipple – Oil & Gas Instrumentation Adapter

The 1/4" Autoclave Male x 1/2" NPT Female Medium Pressure (MP) Hex Nipple is a critical crossover fitting engineered for secure, high-pressure fluid transitions in demanding upstream and midstream operations. Designed to seamlessly adapt Medium Pressure (MP) cone-and-thread connections to standard NPT threaded systems, this adapter is essential for integrating diverse high-pressure instrumentation, chemical injection systems, and control panels.

Manufactured from high-strength, corrosion-resistant alloy or cold-worked stainless steel, the hex-body design provides a secure gripping surface for maximum torque application using standard field tools. The precision-machined 1/4" Autoclave Male end ensures a leak-tight, metal-to-metal seal under extreme pressure, while the 1/2" NPT Female port allows for easy connection to standard pipe fittings and gauges.

Built to withstand heavy vibration, mechanical shock, and aggressive fluids, this medium-pressure hex nipple provides a robust and reliable solution for flowline adaptation and system modifications in the field.

Features & Benefits

• Medium Pressure (MP) Rating: Engineered to safely handle the rigorous demands of medium-to-high pressure oilfield fluid and gas systems.

• Crossover Versatility: Provides a reliable, leak-free transition between 1/4" Autoclave (cone-and-thread) ports and 1/2" NPT components.

• Hex-Body Design: Allows for secure wrenching and straightforward installation, reducing assembly time in the field.

• High-Strength Construction: Built from premium materials to resist galling, mechanical wear, and extreme operational stresses.

• Precision Machined: Ensures superior thread engagement and structural integrity across both connection types.

• Vibration Resistant: Maintains sealing performance even in high-pulsation environments like pump discharge or hydraulic lines.
