O-ring,-017 200909
Product Name: O-Ring, -017 (Part No. 200909)
Description:
This component is an O-ring seal, AS568 standard size -017, specifically designed for high-pressure waterjet cutting systems . It is manufactured from premium-grade elastomer material, specifically Disogrin 6865 polyurethane, and has a clear finish with a 70 durometer hardness rating .
The O-ring functions as a critical static sealing component within the waterjet intensifier pump assembly, providing a leak-proof barrier between mating surfaces such as check valves, cylinder liners, and manifolds . It is designed to maintain sealing integrity under continuous ultra-high pressure operation up to 60,000 PSI (approximately 4,137 bar) and protect critical components from fluid loss and contamination .
This O-ring is an OEM direct replacement part compatible with OMAX, AccuStream, KMT, FLOW, BFT, and WSI waterjet systems . Precision-molded and CNC-inspected to meet OEM tolerances, it ensures reliable sealing compression and hydraulic integrity even under extreme pressure fluctuations . The component is rated for operation up to 200°C depending on the selected material compound and resists chemical degradation from water, hydraulic fluids, and water treatment additives .
Applications:
Provides static sealing in check valve assemblies, cylinder liners, and manifolds of waterjet intensifier pumps
Used as a sealing component within the high-pressure water circuit and hydraulic system
Suitable for ultra-high pressure waterjet systems operating at 60,000 PSI and above
Compatible with OMAX, AccuStream, KMT, FLOW, BFT, and WSI waterjet systems
Features:
Standard AS568 Size -017: Conforms to industry-standard dimensions for precise, reliable fitment in designated seal grooves
Premium Polyurethane Construction: Disogrin 6865 material provides excellent wear resistance, high tensile strength, and superior sealing properties
High-Pressure Rating: Engineered for continuous operation at 60,000+ PSI (4,100+ bar)
Precision-Molded Dimensions: CNC-inspected and tolerance-verified to meet OEM specifications
Wide Temperature Range: Performs reliably from -30°C to +200°C depending on material selection
Chemical Compatibility: Resistant to water, hydraulic fluids, and common water treatment additives
Maintenance:
Failure Diagnosis:
External Water Leakage: Visible water weeping from the pump area or valve body indicates O-ring failure requiring immediate replacement
Pressure Drop: Inability to maintain rated cutting pressure may indicate seal degradation or extrusion
Physical Damage During Inspection: Replace immediately if the O-ring shows signs of nicks, cuts, flattening (compression set), hardening, or cracking
Water Contamination: Milky or discolored hydraulic oil may indicate seal failure allowing water intrusion past the O-ring
Inspection and Replacement Guidelines:
Single-Use Component: This O-ring is a consumable sealing element. Always replace with a new one whenever the associated pump component or valve assembly is disassembled. Do not reuse old O-rings
Preventive Replacement Schedule: For filter housing applications, inspect the O-ring periodically and replace every two years or immediately if leaking is detected
System Overhaul: This O-ring is classified as a "Replace" component during Minor Maintenance, Major Maintenance, and Overhaul procedures
Clean Installation: Before installing a new O-ring, thoroughly clean the groove and mating surfaces with a soft cloth. Remove all debris, old seal residue, and mineral deposits
Lubrication: Apply a thin, uniform layer of manufacturer-recommended high-pressure grease to the O-ring during installation to prevent pinching, rolling, or tearing during assembly
Seating Verification: Ensure the O-ring is not twisted and is fully seated in its groove before reassembling mating components
Full Depressurization: Always fully depressurize the waterjet system (high-pressure water, hydraulic system, and air supply) and follow lockout/tagout procedures before disassembly
Torque Compliance: When reassembling, tighten all retaining components to the specific torque values listed in the equipment service manual to ensure proper O-ring compression without over-compression or damage
Storage: Store spare O-rings in a cool, dry environment (15–25°C, humidity <65%) away from direct sunlight, ozone sources, and chemicals to prevent premature aging
