The GRACO 129509 O-RING, 70 DUROMETER is a sealing component made from a 70 durometer material, typically polyurethane (urethane), designed to provide reliable sealing in various GRACO equipment. Its primary function is to prevent leaks and maintain pressure integrity within fluid handling systems.

Key Features:

• O-Ring
• Height: 0.1 in (0.254 cm), Length: 0.4 in (1.016 cm), Width: 0.3 in (0.762 cm)
• Polyurethane (urethane) rubber, 70 durometer hardness
• Designed for use in GRACO equipment; specific models not listed
• High abrasion resistance
• Excellent tear strength
• Good flexibility
• Resistance to ozone, chemicals, and oils
• Good compression set resistance
• Suitable for dynamic applications (motion, vibration, alternating pressure)

Applications:
Used in industrial, automotive, and aerospace applications where high wear and tear resistance is required. Commonly installed in GRACO spray equipment and fluid handling systems to ensure leak-free operation.

Installation Notes:

• Using genuine GRACO O-rings ensures proper fit, performance, and longevity of equipment, reducing the risk of leaks and downtime.
• Inspect the O-ring for damage or deformation before installation
• Ensure the mating surfaces are clean and free of debris
• Lubricate the O-ring with a compatible lubricant if recommended by the equipment manual
• Avoid twisting or stretching the O-ring during installation
• Replace O-rings during routine maintenance or if signs of wear or leakage are observed
