Product Name: Tube Vise (1/4″) – Part No. 05108782

Description:
This component is a tube vise specifically designed for securing 1/4 inch (0.25) high-pressure stainless steel tubing during the threading and tube preparation process in waterjet cutting systems . This tube vise is listed as a standard component in the official parts diagram for High Pressure Threading Tools (Table 12-37) .

The tube vise functions as a clamping and holding device that securely grips the high-pressure tube, keeping it perfectly stationary and aligned during thread cutting operations. This ensures that the threading die cuts clean, accurate, and concentric threads, which are essential for creating reliable, leak-free connections on the ultra-high-pressure lines of a waterjet system operating up to 60,000-94,000 PSI (approximately 4,137-6,480 bar). Unlike a standard machinist's vise, this specialized tool is designed specifically to hold cylindrical tubing without crushing or damaging the tube surface.

Applications:

• Securely holds 1/4" high-pressure stainless steel tubing during threading operations

• Used in conjunction with retainers (e.g., P/N 05108741) and threading dies as part of the complete threading tool set

• An essential tool for fabricating custom-length high-pressure lines and maintaining the fluid system of a waterjet cutting machine

• Part of the matched tooling set for preparing 1/4" stainless steel tubing for high-pressure fittings

• Typically used for smaller, flexible high-pressure lines in waterjet systems, including those used on motion axes where bending is required

Features:

• Precision Machined: Manufactured to exacting tolerances for a secure and accurate fit with 1/4" high-pressure tubing

• Specialized Design: Engineered specifically to hold cylindrical tubing without causing deformation or surface damage

• Part of a Standardized Kit: This tube vise (05108782) is the designated component for the .25 size, part of a complete family including sizes for .38, .56, .75, and 1.0 tubing

• Critical Tooling Component: The vise itself is not a consumable wear part of the waterjet machine, but it is an indispensable tool for correctly preparing high-pressure fluid lines

• Secure Clamping: Provides stable, vibration-free holding during the threading process to ensure thread accuracy

• Durable Construction: Built to withstand the significant forces required for accurately cutting threads into work-hardened stainless steel tubing

Maintenance:

Usage Guidelines for the Tool Set:

• Secure the Tube Properly: The tube must be held securely and squarely in the vise to ensure the threads are cut straight. Do not overtighten, as this could deform the tubing

• Use as a Matched Set: For best results, always use the tube vise as part of the complete, matched tool assembly, including the appropriate retainer (05108741) and threading die

• Use Cutting Oil: Always apply a high-quality, sulfur-based cutting oil to the tube and threading die during the process. This lubricates the cutting action, prevents galling (seizing) of the stainless steel, and significantly extends the life of the die and vise

• Proper Alignment: Ensure the tube is fully seated and aligned with the threading die axis before beginning the threading operation

Inspection & Care:

• Inspect for Damage: Before each use, inspect the vise jaws and clamping surfaces for any nicks, burrs, or deformation that could cause the tube to slip, become misaligned, or become damaged

• Clean After Use: After each use, thoroughly clean the vise of metal shavings, cutting oil, and debris to prevent rust and maintain precision

• Check Jaw Surfaces: Ensure the gripping surfaces are clean and free from embedded metal particles that could mar the tubing surface

• Storage: Store the complete tool set in a clean, dry, protective case to prevent damage to the precision-machined surfaces

• Lubrication: Periodically lubricate any moving parts (such as screw mechanisms) with light machine oil to ensure smooth operation

• Full Depressurization (Critical): These tools are for preparing new or replacement tubing offline. Never use them on a pressurized system. Always follow lockout/tagout procedures and ensure the waterjet system is fully depressurized before any maintenance or disassembly
