Product Name: HP Gland, .38 (High-Pressure Gland Nut) – Part No. 10078129

Description:
This component is a high-pressure gland nut, specifically designed for 3/8 inch ultra-high pressure (UHP) waterjet tubing systems. It is a precision-machined threaded nut, typically manufactured from heat-treated stainless steel, and serves as the critical fastening component in high-pressure fluid connections .

The primary function of the HP Gland is to secure high-pressure tubing to fittings, valves, and components by compressing a coned insert against a mating cone seat to create a leak-proof, metal-to-metal seal. As part of the 1 Liter Attenuator assembly, four units (Quantity: 4) are required to connect the attenuator to the high-pressure piping manifold .

This part is an OEM-equivalent replacement for Flow part number A-2838 and KMT part number 10078129 . It is interchangeable with WSI part number FIAGL60 .

Applications:

• Secures 3/8 inch high-pressure tubing to the 1 Liter Attenuator mounting manifold .

• Connects high-pressure water lines to valves, cutting heads, and intensifier pump components.

• Suitable for ultra-high pressure waterjet systems operating at 60,000 PSI (4,137 bar) and above .

• Compatible with KMT, Flow, AccuStream, WSI, and other standard waterjet brands .

Features:

• High-Strength Stainless Steel Construction: Provides excellent corrosion resistance and structural integrity under extreme pressure cycling.

• .38 (3/8") Nominal Size: Standard size for medium-flow high-pressure waterjet plumbing.

• Precision-Machined Threads: Ensures smooth engagement with HP fittings and accurate torque application for a reliable metal-to-metal seal.

• Critical Sealing Role: The gland nut is essential for preventing high-pressure water leaks. When used in a four-pack, it securely mounts the 1-Liter Attenuator to the high-pressure manifold .

• Direct OEM Replacement: Interchangeable with Flow A-2838, KMT 10078129, WSI FIAGL60, and AccuStream 1-13158-60-6 .

Maintenance:

• Full Depressurization (Critical): Before any maintenance, turn off the machine, bleed down all high-pressure lines, and follow lockout/tagout procedures.

• Torque Compliance (Critical): Use a calibrated torque wrench to tighten the gland nut to the specific value in the equipment service manual. Over-tightening can damage the cone seat; under-tightening causes leaks.

• Inspection: Before assembly, inspect the threads for galling or damage and inspect the cone seat for nicks or erosion. Replace damaged components immediately.

• Lubrication: Apply a thin, even layer of high-pressure anti-seize compound to the threads only before assembly. Do not apply lubricant to the cone sealing surfaces.

• Cone Seat Care: The sealing surfaces must be kept clean and dry to ensure a proper metal-to-metal seal.

• Two-Wrench Method: When tightening or loosening, use two wrenches—one to counter-hold the fitting body and one to turn the gland nut—to avoid twisting stress on the tubing.

• Replacement: Replace the gland nut if threads are stripped, galled, or corroded, or if the wrench flats are damaged.

• Cross-Reference Part Numbers: Flow A-2838, KMT 10078129, WSI FIAGL60, AccuStream 1-13158-60-6 .
