Holo Krome Pipe Fitting

Holo-Krome Pipe Fittings: Precision-Engineered Sealing Solutions

When a connection absolutely cannot leak, the material and manufacturing quality behind every fitting matter enormously. Holo-Krome — a brand with roots going back to 1929 — brings the same exacting standards that made it famous for critical-application fasteners to its line of pipe fittings, specifically its brass pipe plugs. The result is a product built for environments where pressure-tight sealing is non-negotiable.

What Sets Holo-Krome Pipe Fittings Apart

Holo-Krome's pipe fitting offerings center on brass pipe plugs, engineered for pneumatic instrumentation and any application requiring a secure, leak-free seal. These are not commodity fittings — they reflect the same manufacturing philosophy that defines the rest of the Holo-Krome catalog.

• Precision-Rolled Threads: Holo-Krome pipe plugs feature threads that are precision rolled rather than cut. This process eliminates spiral machining marks that can act as leak paths, producing smooth, fully formed tapered threads that seat firmly and seal reliably under high pressure.
• NPTF / PTF / Dryseal Thread Standards: Holo-Krome brass pipe plugs conform to ASME B1.20.3 and B1.20.5 dryseal standards, ensuring compatibility with systems that demand a metal-to-metal seal without the need for sealant tape or compound.
• Precision-Forged Deep Sockets: The drive sockets on these plugs are forged with smooth, flat walls and a controlled corner radius, distributing driving torque evenly and reducing the risk of socket damage during installation or removal.
• Superior Bursting Resistance: Controlled structural grain flow and greater wall thickness give Holo-Krome pipe plugs a higher threshold for internal pressure, making them well suited to demanding hydraulic and pneumatic systems.
• Stainless Steel Options: In addition to standard brass plugs, Holo-Krome also offers stainless socket pipe plugs for environments where corrosion resistance is a priority.

USA-Made Quality You Can Trace

Holo-Krome products are manufactured and certified at their facility in Wallingford, Connecticut, and the brand has delivered over 90 years of specialized engineering support behind every part it produces. For technicians, maintenance professionals, and engineers who specify components for critical systems, that domestic traceability and quality assurance matters as much as the fitting itself.

Whether you are sealing a port on a hydraulic manifold, capping off an unused pneumatic line, or closing an instrumentation port during maintenance, Holo-Krome brass pipe plugs deliver the consistent, pressure-tight performance that demanding applications require.
