Product Name: O-Ring, .38 x .50 x .06 (AS568 Size -016) – Part No. 10074599

Description:
This component is a precision O-ring seal with nominal dimensions of 0.38 inches inner diameter (ID), 0.50 inches outer diameter (OD), and 0.06 inches cross-section (CS) . According to the official parts diagram for High Pressure Water Filter Assemblies (Table 12-42), this O-ring is listed as Item 6 with a quantity of 1 required per assembly .

The O-ring is manufactured from high-durability elastomer material suitable for high-pressure water applications and is specifically designed as a sealing component within the high-pressure water filter assembly. It provides a critical static seal between the filter housing and other components, preventing high-pressure water leakage and ensuring that unfiltered water does not bypass the filter element .

In high-pressure waterjet systems, high-pressure water filter assemblies serve to remove impurities and debris from the water before it reaches the cutting head . The O-ring is a critical sealing element within these assemblies, alongside components such as the filter housing, filter elements, inlet/outlet connections, and pressure gauges .

Applications:

• Seals the interface between filter components in the High Pressure Water Filter Assembly (Table 12-42)

• Prevents high-pressure water leakage in filtration systems for waterjet cutting equipment

• Serves as a static sealing component for water filter housings and related assemblies

• Suitable for 60,000-94,000 PSI (approximately 4,137-6,480 bar) waterjet systems

Features:

• Precision Dimensions: .38" ID × .50" OD × .06" CS, conforming to AS568 standard size -016

• High-Pressure Compatibility: Engineered for waterjet high-pressure filtration applications 

• Critical Sealing Component: Essential for maintaining filter assembly integrity and preventing contamination bypass

• Static Sealing Application: Specifically designed for non-moving (static) interfaces

• Chemical Compatibility: Suitable for water and common water treatment additives

• Direct OEM Replacement: Listed as Item 6 in High Pressure Water Filter Assemblies documentation 

Maintenance:

Failure Diagnosis (When to Replace):

• External Water Leakage: Visible water weeping from the filter housing indicates O-ring failure requiring immediate replacement 

• Pressure Drop: Inability to maintain system pressure may indicate seal degradation allowing water bypass

• Visible Damage During Inspection: Inspect the O-ring for nicks, cuts, flattening (compression set), hardening, or cracking 

• Filter Performance Issues: If the filter fails to maintain proper differential pressure, the O-ring seal may be compromised

• Scheduled Preventive Maintenance: It is standard practice to inspect and replace O-rings during scheduled filter changes or major pump overhauls

Inspection and Replacement Guidelines:

• Inspection Frequency: High-pressure O-rings should be checked for wear every 20-50 operating hours 

• Single-Use Component: O-rings are consumable sealing elements. Always replace with a new one whenever the filter assembly is disassembled. Do not reuse old O-rings 

• Full Depressurization (Critical): Before any maintenance, fully depressurize the waterjet system, shut off the water supply, and follow lockout/tagout procedures 

• Proper Removal: Use a dental pick or needle nose pliers to carefully remove the damaged O-ring from its groove 

• Surface Preparation: Thoroughly clean the O-ring groove and mating surfaces with a soft, lint-free cloth. Remove all debris, old seal residue, and mineral deposits

• Groove Inspection: Inspect the seal groove for nicks, burrs, or damage that could cut or abrade the new seal

• Lubrication: Apply a thin, uniform layer of manufacturer-recommended high-pressure grease or O-ring lubricant to the new O-ring during installation 

• Proper Seating: Ensure the O-ring is not twisted and is fully seated in its groove. You should see it nest inside the connector if installed correctly 

• Hose Routing: After installation, ensure that the high-pressure hose does not bend or turn aggressively, as this can lead to premature wear or damage of the O-ring 

• Avoid Reuse: O-rings should not be reused once they have been installed and compressed 

• Storage: Store spare O-rings in a cool, dry environment (15-25°C, humidity <65%) away from direct sunlight, ozone sources, and chemicals 

• Component Relationships: This O-ring (Item 6) works in conjunction with the filter body (Item 2) and seal head (Item 7) in the High Pressure Water Filter Assembly
