The GRACO 24A657 is a V-Packing Seal Kit designed for use with Merkur Bellows LB150A and LB150B pumps. It contains standard V-packing seals and is intended to maintain the integrity and performance of the pump by preventing leaks and ensuring proper sealing during operation. The kit is typically used in spray foam and spray application equipment where reliable sealing is critical.

Key Features:

• V-Packing Seal Kit
• LB150A and LB150B (150cc)
• Standard V-packing seals (material not explicitly stated, but typically includes elastomeric or reinforced PTFE options; see below for optional reinforced PTFE kit)
• Merkur Bellows LB150A and LB150B pumps
• Designed for easy maintenance and replacement
• Helps prevent leaks and maintain pump performance
• Available in standard and reinforced PTFE versions for chemical compatibility (24J860 is the reinforced PTFE version for LB150x)
• Includes all necessary components for seal replacement

Applications:
Used in spray foam and spray application equipment, particularly where reliable sealing is required for the Merkur Bellows LB150A and LB150B pumps.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, performance, and longevity of the equipment. Non-genuine parts may compromise safety and reliability.
• Always follow the manufacturer’s instructions for disassembly and reassembly
• Lubricate packings before installation as recommended
• If piston and rod separate during disassembly, always replace the o-ring before reassembly
• Stack o-rings on a bench to differentiate similar sizes if needed
• Use the appropriate packing kit for materials that may cause chemical compatibility concerns (e.g., acid catalyst materials; consider reinforced PTFE seals if needed)
