HYTORC STEALTH-22-LINK Series Ratchet Link is part of the STEALTH series of hydraulic torque wrenches, designed for low-clearance, high-torque bolting applications in industrial settings.

Model: STEALTH-22

Type: Hydraulic Limited-Clearance Torque Wrench with Interchangeable Ratchet Link

Torque Range:

• Imperial: 3,250–21,875 ft-lbs
• Metric: 4,406–29,659 N·m

Drive Size:

• Hex Link Sizes: 2 15/16" to 5" (75–130 mm)
• Available in 6-point and 12-point hex links for versatility

Weight: 15.40 lbs (7.00 kg)

Dimensions:

• Radius (R): 56.21–100.41 mm (2.21–3.95 in)
• Length (L): 243 mm (9.57 in)
• Height (H): 227 mm (8.94 in)
• Width (W): 56 mm (2.20 in)

Accuracy: ±3% (certifiable through calibration traceable to NIST)

Features:

• Slim Design: Narrow drive cylinder housing matches the ratchet link width, ideal for tight spaces with protruding threads or limited clearance above nuts/bolts.
• Dual Piston System: Enhances speed with higher effective rotational speeds per stroke.
• Reaction Pawl: Ensures consistent angular rotation, preventing ratchet back-turning and maintaining bolt torsion.
• 360° x 120° Uni-Swivel: Enables flexible hose positioning for safe and convenient adjustments.
• Integrated Reaction-Free Links: Eliminates kickback for smoother, safer torque application.
• Hands-Free Operation: Optional tool retainer enables hands-free bolting, reducing operator risk and eliminating manual tool holding.
• Quick Couplers: Simplifies connections for efficient bolting operations.
• Torque and Angle Control: Supports precise torque and angle adjustments.
• Subsea Compatibility: Operates effectively in subsea environments.
• ATEX Certified: Some models are ATEX-compatible for hazardous environments.
• Compatibility: Works with HYTORC Washer, HYTORC Nut, and robotic bolting systems for seamless integration.

Accessories:

• HYTORC Washer Retainer: Enables hands-free operation and eliminates the need for a separate reaction fixture.
• ALCO Arm: Reaction arm for low-clearance hydraulic tools.
• HYTORC Nut Driver: Converts torque into tension, preventing galling.
• Reaction Plate Kits: Various reaction fixtures for diverse bolting needs.
• Square Drive Conversion Link: Available for use with hex and Allen sockets.
• Spanners: AB open and 12-point spanners for additional versatility.

Applications: Ideal for low-clearance, high-torque bolting in industries such as oil and gas, power generation, aerospace, and subsea operations, including general maintenance and critical pathways.

Notes:

• Requires a calibrated pressure/torque chart for standard ratchet links, compliant with VDI 2230 standards.
• Maximum operating pressure: 690 bar (10,000 psi).
• Calibration certificate provided, with system accuracy traceable to NIST.
• Maintenance recommended by HYTORC, with preventive maintenance guidelines in the technical manual (available at www.manualslib.com for STEALTH-22).
• Use with HYTORC-approved hydraulic hoses (700 bar working pressure, safety factor of 4) and pump units, ensuring pump functions correctly and is set to 10,000 psi before tool connection.

Specific hex link sizes (e.g., 2 15/16" or 74.6 mm) available; check HYTORC documentation for full range.
