Product Name: HP Plug (1/4″) – Part No. 10078244

Description:
This component is a high-pressure (HP) plug, specifically a 1/4 inch threaded plug designed for use in 60,000 PSI (60K) waterjet cutting systems . The Plug, 1/4 in. is an OEM-equivalent replacement part that directly interchanges with KMT part number 10078244 and Flow part number A-0784-1 . It is also cross-referenced under AccuStream part number 1-13159-60-4 .

The plug is a standard, precision-machined component, typically manufactured from high-strength stainless steel, designed to seal unused ports on high-pressure manifolds, intensifier blocks, check valve bodies, and other hydraulic or water circuit components . Its primary 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 and valve blocks .

• 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.

Features:

• High-Strength Material: Manufactured from hardened, corrosion-resistant stainless steel to withstand extreme pressure cycles.

• Precision Threading: Features precisely cut standard high-pressure threads (typically 9/16-18 UNF for 1/4″ HP systems), designed to engage securely with standard high-pressure ports, ensuring a tight, leak-free seal .

• Corrosion Protection: Stainless steel or treated alloy construction provides excellent resistance to the moist, abrasive waterjet environment.

• Standard Compatibility: Interchangeable with major OEM part numbers including KMT 10078244, Flow A-0784-1, and AccuStream 1-13159-60-4 .

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, undamaged, and the sealing surfaces are intact.

Installation Best Practices

• Thread Lubrication: This is critical. Apply a thin, even layer of high-pressure anti-seize lubricant (such as "Silver Grade" or "Blue Goop") to the threads. This prevents galling (cold welding) of the stainless steel threads and ensures accurate torque application.

• Do Not Use Sealant on Threads: For straight-thread HP plugs that seal via a cone seat or a captured O-ring, sealant tape is generally not required and can contaminate the system.

• 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.

• 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.
