Product Name: Silver Thread Lubricant / Anti-Seize Compound (Part No. 400001-3)

Description:
This component is a high-performance silver-colored anti-seize thread lubricant, specifically formulated for ultra-high pressure waterjet cutting systems. It is a heavy-duty, non-curing paste that provides a protective barrier between metal threads, preventing galling, seizing, and cold welding of stainless steel and other alloy components under extreme pressure and high-cycle operation .

The lubricant is engineered to withstand pressures exceeding 60,000–94,000 PSI (approximately 4,137–6,480 bar) . It ensures that critical high-pressure connections—including check valve retainers, cylinder ends, gland nuts, and high-pressure fittings—can be assembled to the correct torque specification without thread damage, and also permits future disassembly without seizure . This lubricant is commonly included in OEM maintenance kits and is compatible with H2O Jet, Flow, KMT, AccuStream, OMAX, WSI, and BFT waterjet systems .

Applications:

• Lubricating threads on check valve retainers, gland nuts, and high-pressure cylinder ends during pump assembly and maintenance 

• Preventing thread galling and seizure on stainless steel fittings and high-pressure adapters

• Applied during pump rebuilds, major maintenance, and routine servicing of waterjet intensifier systems

• Compatible with H2O Jet, Flow, KMT, AccuStream, OMAX, WSI, and BFT waterjet systems 

Features:

• Ultra-High Pressure Rating: Specifically formulated for extreme pressures up to 94,000 PSI (6,480 bar) 

• Premium Anti-Seize Formula: Heavy-duty, non-curing paste that prevents thread galling, seizing, and cold welding on stainless steel and alloy components 

• High Temperature Resistance: Suitable for applications exposed to high temperatures (capable of withstanding up to 870 °C / 1,600 °F) 

• Smooth Texture: Ideal for protecting fine threads, snug slip fits, and closely mated parts 

• Corrosion Protection: Provides a protective barrier against moisture and chemical degradation in waterjet environments

• Torque Accuracy: Ensures consistent friction coefficient for accurate torque application 

Maintenance:

When to Use (Critical Applications):

• Every High-Pressure Threaded Connection: Apply to all stainless steel threads during reassembly of intensifier pumps, check valves, fittings, and cutting head components 

• Check Valve Retainers: Essential for lubricating retainer threads during check valve service 

• High-Pressure Cylinder Threads: Apply to cylinder body threads before installation

• Tube Fittings: Always apply a thin layer to the threads of HP fittings, glands, and collars when assembling high-pressure water lines

Application Guidelines:

• Thin, Even Layer: Apply a thin, uniform coating to male and female threads. Avoid over-application, which can trap contaminants 

• Clean Threads First: Before applying lubricant, ensure threads are clean, dry, and free from debris, old lubricant, or corrosion 

• Do Not Apply to Sealing Faces: Apply lubricant to threads only. Avoid contact with precision cone sealing surfaces or valve seats that require metal-to-metal contact for sealing

• Reapply After Disassembly: Always clean and reapply fresh lubricant whenever components are disassembled and reassembled

• Use with Torque Wrench: After applying lubricant, tighten components to the specific torque values listed in the equipment service manual for accurate and consistent clamping force
