The 1/4" MPT Heavy-Duty Brass Hex Plug is an essential industrial-grade fitting designed to provide a permanent or temporary leak-proof seal for unused ports in beverage manifolds, CO2 regulators, and water filtration systems. Precision-machined from high-performance brass, this solid plug features 1/4" Male Pipe Threads (MPT) and an integrated hexagonal head for easy installation with a standard wrench. Its robust construction is engineered to withstand high-pressure surges and thermal expansion, making it a reliable choice for commercial kitchens, breweries, and industrial fluid control applications.

  • Configuration: Threaded Hex Head Pipe Plug
  • Thread Interface: 1/4" Male Pipe Thread (MPT / NPT)
  • Material: Heavy-Duty Commercial Brass (Corrosion-Resistant)
  • Head Type: Hexagonal for maximum torque and easy removal
  • Durability: Industrial-grade finish designed for high-pressure gas and liquid environments
  • Application: Capping manifold ports, regulator outlets, pump housings, and boiler drains
  • Installer Advantage: Standardized NPT sizing ensures a precise fit for universal repair tasks
Technician's Note: This hex plug is a "must-have" for any draught technician's service kit. It is the fastest way to safely bypass a leaking secondary regulator or cap off a CO2 manifold port that is not currently in use. When installing into a brass or stainless manifold, always apply 2–3 wraps of PTFE thread tape (Teflon tape) or a small amount of food-grade pipe dope to the threads. This ensures a gas-tight seal and prevents "galling," making it much easier to remove the plug later if you decide to expand your beverage system.
