400007-1-Plug-HP-40k-60k.1990.3-1
Product Name: High-Pressure Plug / HP Plug (40k–60k) – Part No. 400007-1
Description:
This component is a high-pressure (HP) plug designed for waterjet cutting systems rated at 40,000 to 60,000 PSI (approximately 2,758 to 4,137 bar). It is a precision-machined threaded plug manufactured from high-strength, corrosion-resistant stainless steel, engineered to seal unused ports on high-pressure manifolds, check valve bodies, intensifier blocks, and other hydraulic or water circuit components. Its function is to provide a reliable, leak-proof seal, preventing the escape of ultra-high-pressure water or hydraulic fluid.
Applications:
Sealing unused high-pressure ports on waterjet intensifier pump manifolds.
Blocking off ports on check valve bodies, accumulator blocks, or distribution manifolds.
Providing a permanent seal for test ports or auxiliary ports not in use during standard cutting operations.
Compatible with the same high-pressure fitting standards as collar and gland assemblies.
Features:
High-Strength Material: Manufactured from hardened stainless steel or high-grade alloy to withstand the extreme pressure and cyclic stress of waterjet operation.
Precision Threading: Features precisely cut threads designed to engage securely with standard high-pressure ports, ensuring a tight, leak-free seal.
Corrosion Protection: Stainless steel construction provides excellent resistance to the moist, abrasive waterjet environment.
Standard Compatibility: Interchangeable with major OEM part numbers including H2O Jet #400007-1, KMT #10078244, and 49864648.
Maintenance:
Inspection and Reuse
Visual Examination: Before installation, inspect the plug threads for any signs of galling, corrosion, or mechanical damage. Examine the hex drive or head for rounding or cracks.
Reusability: A well-maintained plug is a durable component. Unlike soft seals, it can be reused multiple times if the threads remain clean and undamaged.
Installation Best Practices
Thread Lubrication: This is critical. Apply a thin, even layer of high-pressure anti-seize lubricant (such as "Blue Goop" or Silver Grade compound) to the threads. This prevents galling (cold welding) of the stainless steel threads and ensures accurate torque application.
Torque Compliance: Tighten the plug to the specific torque value listed in the equipment service manual. Do not over-tighten, as this can stress the port threads; do not under-tighten, as this will cause high-pressure leaks.
Seal Check: Some plug designs incorporate a bonded washer or O-ring. If the plug features a static seal, it is a single-use component and must be replaced with a new one each time the plug is installed.
Full Depressurization (Critical): Always fully depressurize the waterjet system (high-pressure water, hydraulic system, and air supply) and follow lockout/tagout procedures before installing, removing, or servicing the plug.
