Product Name: O-Ring Lubricant / High-Pressure Seal Grease (Part No. 400034-1)

Description:
This component is a specialized high-pressure lubricant, commonly known as O-ring lubricant or seal grease, specifically formulated for waterjet cutting systems . It is designed to lubricate and protect O-rings, dynamic seals, packings, and plungers during assembly and maintenance of high-pressure intensifier pumps.

The lubricant is manufactured from synthetic, non-petroleum-based compounds that provide excellent adhesion to both metal and elastomer surfaces . It remains chemically stable and effective under continuous ultra-high pressure operation up to 60,000–90,000 PSI (approximately 4,137–6,200 bar) and across wide temperature ranges . Unlike general-purpose greases, this formulation is specifically engineered not to cause swelling or degradation of standard waterjet seal materials, including urethane, PTFE, and Viton .

A thin, uniform film of this lubricant on O-rings and static seals eases installation, prevents seal damage (rolling, pinching, or tearing), reduces friction, and delivers a long-lasting barrier against water and hydraulic fluid . It is an essential maintenance consumable for professional seal installation, ensuring proper seating and extending the service life of high-pressure sealing components .

This lubricant is fully compatible with H2O Jet systems and cross-compatible with major waterjet brands including KMT, AccuStream, FLOW, OMAX, and WSI .

Applications:

• Lubricating O-rings and dynamic seals during installation into high-pressure cylinders and valve assemblies 

• Coating high-pressure seals, packings, and plungers during pump rebuilds and major maintenance 

• Assisting in the assembly of check valves, on/off valves, and intensifier wet-end components

• Protecting sealing surfaces during maintenance and reducing friction during initial pump startup 

• Compatible with H2O Jet, KMT, AccuStream, FLOW, OMAX, and WSI waterjet intensifier systems 

Features:

• Ultra-High Pressure Stability: Formulated to withstand continuous operation at 60,000–90,000 PSI without breaking down 

• Material Compatibility: Safe for use with all standard waterjet seal materials (urethane, PTFE, Viton) and will not cause swelling or degradation 

• Reduced Assembly Friction: Provides a thin protective film that minimizes friction during seal installation, preventing the rolling or pinching that often damages new seals and leads to leaks 

• Non-Petroleum Formula: Synthetic, non-petroleum-based compound ensures chemical compatibility with high-pressure waterjet environments 

• Corrosion Protection: Creates a lasting protective barrier against water ingress and corrosion on metal components and sealing surfaces 

• Smooth Operation: Ensures smooth startup after pump rebuilds by preventing dry running of critical reciprocating parts 

• Wide Temperature Range: Remains effective across the temperature extremes encountered in waterjet pump operation 

• Consumable Classification: Designed as a maintenance consumable that must be replenished every time seals are replaced or pump maintenance is performed 

Maintenance:

When to Use:

• Every Seal Replacement: Apply to all new O-rings, dynamic seals, and backup rings during every seal installation or pump rebuild 

• Component Assembly: Use during assembly of check valves, on/off valves, and hydraulic cartridges to ensure smooth fitting of components 

• Plunger Installation: Apply to plunger surfaces and seals when rebuilding the intensifier pump high-pressure cylinder assembly

Application Guidelines:

• Thin, Even Application: Apply only a thin, uniform film to the seal and component bore . Excess grease can attract abrasive dust or particulate contamination during pump operation

• Surface Preparation: Ensure all sealing surfaces, O-ring grooves, and bores are completely clean and dry before application to ensure the lubricant adheres correctly

• Avoid Over-Application: Do not apply lubricant to metal sealing faces (e.g., cone seats) that rely on metal-to-metal contact for sealing

• Full Depressurization (Critical): Always fully depressurize the waterjet system (high-pressure water, hydraulic system, and air supply) and follow lockout/tagout procedures before disassembling any component for seal replacement

Storage:

• Sealed Container: Keep the lubricant container tightly sealed when not in use to prevent contamination by abrasive dust or drying out 

• Environment: Store in a clean, cool, dry environment away from direct sunlight, ozone sources, and chemicals to prevent degradation 

• Clean Application: Use a clean applicator or dispensing method to avoid introducing contaminants into the lubricant container

Consumable Classification:
This product is classified as a maintenance consumable. Although it is not a mechanical spare part, it is an essential material used during equipment assembly, seal replacement, and routine maintenance . It is consumed during every seal installation procedure and must be replenished regularly to ensure optimal sealing and lubrication performance .
