Product Name: Feed Tube Adapter (Autoline™ Abrasive Nozzle Assembly) – Part No. 05076989

Description:
This component is the feed tube adapter, a specialized fitting specifically designed for the Autoline™ series abrasive waterjet cutting head assembly . Its primary function is to serve as the connection interface between the abrasive feed line (polyurethane tube) and the cutting head mixing chamber, ensuring a secure, leak-free path for garnet abrasive to be drawn into the high-pressure waterjet .

Listed as Item 4 in the official parts diagram for the Autoline™ Abrasive Nozzle Assembly (Table 12-45), this adapter integrates seamlessly with the nozzle body, wear insert, and retaining components to maintain the critical vacuum required for the Venturi effect . By providing a precise, airtight connection, it ensures consistent abrasive flow for cutting hard materials such as metal, stone, and ceramics . It is commonly cross-referenced under OEM numbers CH2006 and 0560996525 .

Applications:

• Connects the abrasive supply hose (poly tube) to the Autoline™ cutting head body .

• Serves as the intake port for garnet abrasive into the mixing chamber .

• Used specifically in Autoline™ I and Autoline™ II abrasive nozzle assemblies .

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

Features:

• Precision Fit: Machined to exact OEM specifications for a secure connection to the Autoline™ nozzle body (P/N 05073820) .

• O-Ring Sealed: Works in conjunction with specific O-rings (e.g., P/N 05081518) to ensure an airtight seal, preventing loss of vacuum and abrasive leakage .

• Corrosion-Resistant Construction: Manufactured from high-strength, wear-resistant material to withstand the abrasive nature of garnet flow.

• Direct OEM Replacement: Interchangeable with original equipment manufacturer specifications (Item 4 in Table 12-45) .

• Lightweight: Weight is approximately 0.036 kg (0.079 lbs), facilitating easy handling during maintenance .

Maintenance:

Failure Diagnosis (When to Inspect/Replace):

• Loss of Abrasive Flow: If the cutting head fails to draw abrasive, the adapter or its sealing interface may be damaged or clogged.

• External Abrasive Leakage: Visible garnet dust accumulating around the connection point indicates a failed seal (O-ring) or damaged adapter threads.

• Visible Cracks or Wear: Inspect the adapter body for cracks, deformation, or thread damage during routine cutting head maintenance.

• O-Ring Degradation: When disassembled, check the O-ring (P/N 05081518) for nicks, cuts, flattening, or hardening; if damaged, the seal is compromised .

Inspection and Replacement Guidelines:

• Full Depressurization (Critical): Before any maintenance, fully depressurize the waterjet system (high-pressure water, hydraulic system, and air supply) and follow lockout/tagout procedures.

• Disassembly: The adapter is secured to the nozzle body by a set screw (P/N 05077292) . Loosen the set screw to remove the adapter.

• O-Ring Replacement: The O-ring (P/N 05081518) is a single-use consumable. Always install a new, lubricated O-ring whenever the adapter is removed .

• Thread Care: Clean all threads thoroughly. If the set screw or adapter threads are damaged, replace the component immediately to prevent air leaks (loss of vacuum).

• Replacement Criteria: Replace the adapter if threads are damaged, the body is cracked, or persistent air/abrasive leakage occurs despite new O-rings.

• Component Relationships: This adapter (Item 4) works in conjunction with the Nozzle Body (Item 2), Wear Insert (Item 3), and Retaining Knob (Item 9) . When replacing wear components, inspect the adapter for damage.
