1251H Series Hex Head NPTF Pipe Plug Hydraulic Adapter -Configure your measurements

The Dixon 1251H Series is the quintessential industrial plug for blocking lines or tapered threaded ports. Unlike common plumbing plugs (malleable iron) that break under high pressure, the 1251H series is machined from Solid Carbon Steel, allowing it to withstand the demands of modern hydraulic systems.

Its thread type is NPTF (Dryseal). This means the threads are designed to deform slightly when tightened, creating a metal-to-metal mechanical seal that better resists leaks.

Technical Features:

• Hex Head (H): Provides a secure gripping surface, preventing the tool from slipping when applying the necessary torque to seal the tapered thread.

• Zinc Plated Finish: The zinc coating protects the steel against oxidation and environmental corrosion, extending the part's lifespan.

• SAE 130109C Standard: Complies with dimensional and safety standards for pipe plugs in automotive and industrial applications.

• Safety: Ideal for closing diagnostic ports, oil drains, or unused auxiliary outlets in machinery.
