The GRACO 867633 is a Stat-O-Seal, a specialized sealing component designed to provide a reliable, controlled confinement seal for fasteners in GRACO equipment. Its material is not explicitly stated in available sources, but Stat-O-Seals typically use an elastomeric seal (such as nitrile) housed within a metal retainer. This part is intended to prevent leaks and ensure secure sealing at fastener joints in fluid handling systems.

Key Features:

• Seal, Stat-O-Seal
• Elastomeric seal (likely nitrile) within a metal retainer
• Designed for use with GRACO equipment and compatible fasteners
• Pre-calculated interference factor for optimal compression
• Teardrop-shaped elastomeric seal for controlled confinement
• No machined O-ring grooves required in mating flange
• Positive alternate load path for fastener torque
• Protective gland area for seal confinement
• Reliable sealing under compression without over-squeezing

Applications:
Used for sealing fasteners in GRACO fluid handling and lubrication systems, preventing leaks at critical joints.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, performance, and reliability, reducing the risk of leaks and equipment failure.
• Ensure the fastener head diameter exceeds the maximum 'E diameter' of the Stat-O-Seal to maintain controlled confinement sealing
• Compress the seal down to the retainer thickness during installation
• Inspect the seal and mating surfaces for damage before installation
• Follow GRACO equipment manual for specific installation procedures
