Static Seal 301635
Product Name: Ring Seal / Static Seal (Part No. 301635)
Description:
The Ring Seal 301635 is a precision-engineered static sealing component specifically designed for high-pressure waterjet intensifier pumps . This white-colored seal has an outer diameter (OD) of 0.813 inches and an inner diameter (ID) of 0.692 inches . It is manufactured by AccuStream (a Hypertherm brand) under OEM number 1-11992, and is fully compatible with OMAX waterjet systems . The seal is a critical component in the pump's sealing stack, providing leak-proof static sealing between fixed components such as check valve bodies, port adapters, and manifold connections under continuous operation at pressures up to 60,000 PSI (approximately 4,137 bar).
Applications:
Installed between fixed components in waterjet intensifier pumps and manifold assemblies
Seals stationary interfaces in check valve bodies, port adapters, and high-pressure cylinder connections
Suitable for ultra-high pressure waterjet systems operating at 60,000 PSI and above
Compatible with OMAX, AccuStream, KMT, FLOW, WSI, and BFT waterjet systems
Features:
Precision Dimensions: 0.813 inches OD × 0.692 inches ID for exact fit in designated seal grooves
White Color Coding: Distinctive white appearance for easy identification during maintenance
Premium Material Construction: Manufactured from high-grade elastomer material for chemical compatibility and pressure durability
High-Pressure Rating: Engineered for continuous operation at 60,000+ PSI (4,100+ bar)
OEM Quality: Direct replacement for OMAX #301635, AccuStream #1-11992, and WO040037
Component Integration: Listed as a "Replace" component in Minor Maintenance and Major Maintenance procedures
Maintenance:
When to Replace (Failure Diagnosis):
External Water Leakage: Visible water weeping from the check valve body or manifold area indicates seal failure requiring immediate replacement
Pressure Drop: Inability to maintain rated cutting pressure may indicate seal degradation or compression set loss
Visible Damage During Inspection: Inspect the seal for signs of nicks, cuts, flattening (compression set), hardening, or cracking
Scheduled Maintenance: This seal is classified as a "Replace" component during Minor Maintenance, Major Maintenance, and Overhaul procedures, as documented in manufacturer service guides
Inspection and Replacement Guidelines:
Single-Use Component: The ring seal is a consumable sealing element. Always replace with a new one whenever the mating assembly (check valve body, port adapter, or manifold) is disassembled during maintenance
Kit Replacement: This seal is included as a standard component in maintenance kits, including the Basic Pump Seals Kit (P/N 303019), which contains 3 units of 301635 , as well as the Minor Maintenance Kit (302700) and Pump Seal Repair Kit (303019)
Clean Installation: Before installing a new seal, thoroughly clean the sealing groove and mating surfaces with a soft cloth. Remove all debris, old seal residue, mineral deposits, and corrosion
Groove Inspection: Inspect the seal groove for nicks, burrs, sharp edges, or damage that could cut or abrade the new seal
Lubrication: Apply a thin, uniform layer of manufacturer-recommended high-pressure grease to the seal during installation to prevent pinching, rolling, or tearing during assembly
Seating Verification: Ensure the seal is correctly seated in its groove without twisting or warping 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 disassembling any static seal interface
Torque Compliance: When reassembling, tighten the port adapter or retainer nut to the specific torque values listed in the equipment service manual to ensure proper seal compression without over-compression
Inspect Mating Surfaces: Check the mating housing sealing surfaces for nicks, scratches, or damage that could compromise seal integrity. Replace damaged components as needed
Storage: Store spare seals in a cool, dry environment (15–25°C, humidity <65%) away from direct sunlight, ozone sources, and chemicals to prevent premature aging
