Vertex Coupling 2617I — Threaded 7/8-9" connection, 1-1/4×1-7/8" compact design

A coupling designed for secure mechanical and fluid connections in workshop and industrial fittings, optimised for installations requiring a small footprint and standard 7/8-9" thread compatibility.

• Threaded 7/8-9" standard compatibility
• Compact 1-1/4×1-7/8" footprint
• Robust Vertex manufacturing quality
• Suitable for standard industrial fittings

Dependable threaded connection for secure assemblies

The core advantage of this component is a reliable threaded connection that results from its standard 7/8-9" specification. This ensures repeatable mechanical engagement and predictable torque behaviour when mated with corresponding fittings. A standard thread form simplifies inventory planning, reduces assembly errors and supports fast installation cycles in production environments. The product’s design focuses on consistent performance rather than decorative features, supporting uninterrupted workflow and improved process reliability.

Space-saving design for tight installations

With overall dimensions of 1-1/4×1-7/8", the unit is engineered for situations where installation space is limited. The compact footprint enables close-coupled assemblies and easier routing of adjacent components without sacrificing mechanical stability. This characteristic is particularly useful in crowded machine rooms, control cabinets and assemblies where every millimetre of clearance counts. The combination of compact size and standard threading allows integration into existing setups with minimal layout changes.

Compatibility across common industrial applications

The coupling is suitable for use in a wide range of industrial applications that accept a 7/8-9" threaded interface, including mechanical linkages and standard fluid or pneumatic assemblies where such connections are specified. Its standardised form factor supports interoperability with many established components and reduces the need for bespoke adaptors. Clear identification of the specification simplifies procurement and ensures that the component can be matched reliably to mating parts during assembly planning.

Practical integration and maintenance benefits

Installation is straightforward when correct torque and sealing practices are applied, and the component can be integrated into existing maintenance routines without special tooling. Its standard thread means replacements are simple to source and stocking is predictable. Where sealing is required, conventional tape or jointing compounds for threaded connections can be used in accordance with system requirements. Images and technical drawings are supplied to assist with verification and to support assembly checks during routine inspection.
