4. Setup and Installation

Proper installation is crucial for the effective sealing performance of the gasket. Follow these steps carefully:

1. Preparation: Ensure that both flange faces are clean, dry, and free from any debris, old gasket material, or surface imperfections.
2. Alignment: Carefully align the gasket with the bolt holes of one flange. The full face design ensures complete coverage of the flange sealing surface.
3. Positioning: Place the gasket evenly between the two flanges. Ensure it is centered and not pinched or misaligned.
4. Bolt Insertion: Insert all bolts through the aligned bolt holes of the flanges and gasket.
5. Tightening: Hand-tighten all nuts. Then, using a torque wrench, tighten the bolts in a star pattern (cross-pattern) to the manufacturer's recommended torque specifications for the specific flange and bolt size. This ensures even compression of the gasket.
6. Final Check: After initial tightening, wait a short period (e.g., 15-30 minutes) and re-check the torque on all bolts, as the gasket material may settle.

Note: Always refer to the specific flange and bolt manufacturer's guidelines for torque values and tightening procedures.

5. Operating Instructions

Once installed, the gasket operates passively as a static seal. Ensure the system operates within the specified temperature and pressure limits to maintain the integrity of the seal.

• Temperature Range: The gasket is designed to operate effectively within a temperature range of -20°F to 180°F. Exceeding these limits may compromise the gasket's sealing capabilities.
• Pressure Rating: This gasket is rated for Class 150# applications. Ensure the system pressure does not exceed the rating of the flanges and gasket assembly.
• Chemical Compatibility: While SBR rubber offers good general resistance, verify its compatibility with the specific media being conveyed to prevent degradation.

6. Maintenance

Regular inspection and timely replacement are key to preventing leaks and ensuring system reliability.

• Visual Inspection: Periodically inspect the flange connection for any signs of leakage, material degradation, cracking, or bulging of the gasket.
• Retorquing: In some applications, especially after initial operation or significant temperature cycles, retorquing the flange bolts may be necessary to maintain optimal compression.
• Replacement: Gaskets are generally considered single-use items. Always replace the gasket when disassembling a flange joint or if any signs of wear or damage are observed. Do not reuse old gaskets.
• Storage: Store unused gaskets in a cool, dry place away from direct sunlight, ozone, and harsh chemicals to prevent premature aging.

7. Troubleshooting

If a leak occurs at the flange joint, consider the following potential causes and solutions:

• Insufficient Torque: The bolts may not have been tightened to the correct specifications.
  Solution: Carefully retorque the bolts following the star pattern and recommended torque values. If the leak persists, disassemble and replace the gasket.
• Uneven Compression: Bolts may have been tightened unevenly.
  Solution: Disassemble the joint, inspect the gasket and flange faces, and reassemble with a new gasket, ensuring even and proper torque application.
• Damaged Gasket: The gasket may have been pinched, cut, or otherwise damaged during installation, or it may have degraded over time.
  Solution: Disassemble the joint and replace the gasket with a new one.
• Flange Face Damage: Scratches, gouges, or corrosion on the flange sealing surfaces can prevent a proper seal.
  Solution: Inspect flange faces. If damaged, repair or replace the flanges.
• Incorrect Gasket Material/Size: The gasket may not be suitable for the application's temperature, pressure, or chemical environment, or it may be the wrong size.
  Solution: Verify that the gasket specifications match the application requirements.
