The GRACO 17N893 is a Ludecke Mortar Coupling designed to connect 25 mm female mortar hose fittings to 1 inch British Standard Pipe Parallel (BSPP) female threads. It is typically constructed from robust materials suitable for heavy-duty applications, such as steel or alloy, and is intended for use in GRACO equipment handling thick, abrasive materials like mortar, stucco, or fireproofing compounds.

Key Features:

• Mortar Coupling
• 25 mm (f) mortar to 1 in BSPP (f)
• Compatible with GRACO ToughTek and similar mortar/stucco/fireproofing pumps and hoses
• Tool-less, quick knockdown design for fast assembly and maintenance
• Designed for heavy materials and rugged jobsite conditions
• Reliable connection for high-viscosity, abrasive materials

Applications:
Used in GRACO equipment for pumping and transferring thick, abrasive materials such as mortar, stucco, and fireproofing compounds. Suitable for construction, fireproofing, and exterior insulation and finish system (EIFS) applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment, reducing the risk of leaks, equipment damage, and downtime.
• Ensure both mating surfaces are clean and free of debris before installation
• Use appropriate tools for tightening, but avoid over-tightening to prevent damage to threads or gaskets
• Inspect gaskets and seals regularly and replace if worn or damaged
• Follow manufacturer guidelines for torque specifications if available
• Regularly inspect the coupling for signs of wear, corrosion, or damage
• Clean after each use to prevent material buildup
• Replace gaskets and seals as part of routine maintenance
