Wire Rope Sleeves & Swage Buttons

Holloway Houston stocks a massive inventory of Crosby National COLD TUFF® swage fittings. Unlike standard commercial fittings, COLD TUFF products undergo a proprietary thermal processing method that ensures the steel is ductile enough to flow around the wire strands without cracking, yet tough enough to maintain a termination efficiency of 96% to 100% of the wire rope's catalog strength.

Every fitting is fully traceable and designed to work seamlessly with standard swaging dies.

Product Lines & Applications

Crosby S-505 Standard Steel Sleeves

The industry standard for creating "Flemish Eye" or turnback splices on wire rope.

• Application : Used to form eyes in wire rope slings, winch lines, and bridle assemblies.
• Performance : When properly swaged, the S-505 sleeve creates a termination that equals or exceeds the breaking strength of the wire rope itself (depending on rope construction).
• Popular Choice : Check the Crosby S-505 Standard Steel Swaging Sleeves for sizes ranging from 1/4" to 4".

Crosby S-409 Swage Buttons

Designed to terminate the end of a wire rope, often used as a stop on a winch drum or to prevent a rope from pulling through a block.

• Application : Dead-ending wire rope, drum socketing, and ferrule stops.
• Design : Compact profile allows for use in tight tolerance areas.
• Popular Choice : Check the Crosby S-409 National COLD TUFF Swage Buttons for secure, low-profile terminations.

The COLD TUFF® Advantage

Why choose Crosby National fittings over generic imports?

• Ductility : The "COLD TUFF" thermal process alters the grain structure of the steel. This allows the metal to deform (flow) during the swaging process without forming microscopic stress cracks.
• Low Temperature Toughness : These fittings retain their ductility even in extreme cold, making them the standard for North Sea and Arctic drilling operations.
• Die Compatibility : Designed to work with standard National Swage die sets, ensuring a verified "After Swage Dimension" (ASD).

Capacity Range & Sizes

We stock swage fittings for everything from small aircraft cable to massive mooring lines.

• Small Diameter : 1/8" to 3/8" for utility and winch lines.
• Standard Rigging : 1/2" to 1-1/2" for standard wire rope slings.
• Heavy Lift : Large bore sleeves up to 4" (Duplex) for major heavy-lift grommets.

Technical Specifications & Compliance

Holloway Houston ensures all termination hardware meets strict quality control standards.

• Traceability : Hard stamped with size and trace code (on sizes 5/16" and larger).
• Efficiency : Designed to achieve 100% of the wire rope's catalog strength when applied to 6x19 or 6x37 IWRC EIPS wire rope (per Crosby termination instructions).
• Compliance : Meets requirements for wire rope sling fabrication under ASME B30.9 .

Holloway Houston Swaging Services

• Fabrication : We don't just sell the sleeves; we operate one of the largest swaging facilities in the US. We can fabricate custom wire rope slings to your exact specifications.
• Proof Testing : We can proof load swaged assemblies on our test beds to verify the integrity of the termination.
• Die Inspection : Our technical team can advise on the correct die selection and After Swage Dimensions (ASD) to ensure your field presses are compliant.

Complete Your Assembly

A sleeve is just one part of the sling. Pair these fittings with our high-quality Wire Rope (available in bulk or cut length). For field swaging, ensure you have the correct Swaging Dies and Go/No-Go Gauges to verify your finished dimensions. If you are building winch lines, check our Thimbles section to protect the eye from wear.
