Prevost Hexagonal Male Plug

Description

Prevost Hexagonal Male Plug

The Professional Solution for Permanent Port Sealing

The Prevost Hexagonal Male Plug is a high-performance threaded fitting designed to securely seal off unused ports in manifolds, air tanks, valve blocks, and compressors. Engineered for industrial environments, this plug provides a permanent, leak-proof closure that can withstand high-pressure spikes and extreme temperature fluctuations.

Constructed with a prominent hexagonal head, this plug is designed for easy installation and removal with standard wrenches, ensuring a reliable seal in any pneumatic or hydraulic layout.

Key Features

• Secure Port Termination: Ideal for closing off auxiliary ports in a distribution header or manifold when they are not in use, ensuring the rest of the system maintains full pressure.
• Heavy-Duty Hexagonal Head: The deep, precision-machined wrench flats allow for maximum torque application. This ensures the plug can be seated deeply for a permanent seal or loosened easily even after years of service.
• Industrial Brass Construction: Naturally resistant to corrosion and oxidation, making it suitable for systems containing moisture, compressor oils, or inert gases.
• Precision-Cut Tapered Threads: Available in NPT or BSPT configurations. The tapered design creates a “wedge” fit that becomes tighter as the plug is driven in, forming a robust mechanical bond.
• Low-Profile Design: While providing a solid grip for tools, the head remains compact, preventing the plug from becoming a snag hazard or interfering with surrounding components.

Technical Specifications

Common Applications

• Manifold Capping: Sealing the end of an air distribution block or unused outlet ports.
• Tank Maintenance: Closing off inspection or drain ports on portable and stationary air receiver tanks.
• Valve Modification: Plugging the exhaust or auxiliary ports on directional control valves during system reconfiguration.
• Automotive Repair: Sealing oil or coolant galleries during engine pressure testing or long-term storage.

Installation Note

For the most reliable airtight seal, it is recommended to apply a small amount of thread sealant or PTFE tape to the male threads before installation. This fills the microscopic gaps between the threads and ensures a 100 percent leak-free connection, even under maximum industrial pressures.
