Brass Cap Plug

Product Description

Brass cap plugs (or hex caps) are used to seal the male-threaded ends of pipes, tubes, and fittings. Unlike a standard plug that fits inside a female port, a cap threads over the outside of a connection to provide a secure, pressure-tight seal.

Technical Overview

• Thread Styles: Available in NPT, BSP, and Metric formats to match standard industrial fittings.

• Temperature Range: Generally rated for -53C to +121C (-65F to +250F), depending on the specific alloy and pressure.

• Material Integrity: Manufactured from solid brass, offering excellent resistance to corrosion from water, oil, and chemicals.

Key Applications

• End-of-Line Sealing: Safely capping off unused water or gas lines in industrial and residential plumbing.

• HVAC Systems: Protecting flare connections or service valves from debris and leaks.

• Hydraulics: Providing a robust seal for low-to-medium pressure hydraulic ports during maintenance or transport.

• Automotive: Used in fuel and cooling systems where a reliable, non-sparking metal seal is required.

  Product Features

  • Hexagonal Body: Designed with a heavy-duty hex flats for high-torque tightening with standard wrenches.

  • Vibration Resistance: The natural properties of brass allow for a secure fit that resists loosening due to mechanical vibration.

  • Low Magnetic Permeability: Ideal for applications where magnetic interference must be minimized.
