The GRACO 17N892 is a Ludecke Mortar Coupling designed to connect 50 mm (female) mortar lines to 2 inch BSPP (female) fittings. It is a robust, engineered component intended for use in heavy-duty fluid handling systems, particularly in GRACO ToughTek fireproofing and stucco pumps. The material is not explicitly specified, but typical GRACO mortar couplings are constructed from durable metals such as steel or stainless steel, with compatible gaskets for sealing.

Key Features:

• Ludecke Mortar Coupling
• 50 mm (f) mortar to 2 in BSPP (f)
• Durable metal (steel or stainless steel, not explicitly specified), with compatible gasket
• GRACO ToughTek fireproofing and stucco pumps, 50 mm mortar lines, 2 inch BSPP fittings
• Tool-less, quick assembly/disassembly for fast maintenance
• Designed for heavy materials and rugged jobsite conditions
• Reliable sealing with compatible gasket
• Engineered for seamless and efficient fluid handling

Applications:
Used in GRACO ToughTek fireproofing and stucco pump systems for connecting mortar lines to equipment or hoses, enabling efficient transfer of heavy materials such as fireproofing mortar or stucco.

Installation Notes:

• Using genuine GRACO parts ensures optimal fit, performance, and safety, reducing the risk of leaks or equipment failure.
• Ensure both mating surfaces are clean and free of debris before assembly
• Use the correct gasket for sealing (GRACO part 17N874 for 50 mm couplings)
• Hand-tighten the coupling, then secure with the locking arm or pin as applicable
• Regularly inspect the coupling and gasket for wear or damage and replace as needed
