{E} 4" Silicon Flex Gasket

Keep your air compressor operating reliably with high-quality replacement gaskets, O-rings, and seals from Edmac Compressor Parts. Designed to help maintain airtight and fluid-tight connections throughout the compressor system, these sealing components play a critical role in preventing air, oil, and fluid leaks while supporting efficient compressor operation.

Air compressors rely on a variety of gaskets, O-rings, and seals to maintain pressure integrity between components and prevent the loss of compressed air or lubricant. Over time, exposure to heat, pressure, vibration, lubricant, and environmental conditions can cause sealing components to wear, harden, crack, flatten, or become damaged. Worn seals may contribute to air leaks, oil leaks, reduced efficiency, increased energy consumption, and unplanned maintenance issues.

Edmac offers OEM and replacement gaskets, O-rings, and seals for a wide range of rotary screw, reciprocating, and industrial air compressors. Find the correct replacement using your compressor model, serial number, component information, or OEM part number.

Gaskets, O-rings, and seals help prevent the leakage of compressed air, lubricant, and other fluids between compressor components. These sealing elements are used throughout the compressor to maintain pressure integrity and support reliable operation. Properly functioning seals help ensure that air and lubricant remain within their intended systems during operation.

Over time, sealing components can deteriorate due to age, heat, pressure, vibration, and exposure to lubricants or contaminants. Damaged or worn seals may allow air or lubricant to escape, potentially affecting compressor efficiency and performance. Replacing these components during recommended service intervals or repairs helps maintain proper sealing and system reliability.

Common signs that gaskets, O-rings, or seals may require inspection or replacement include visible air leaks, lubricant leaks, pressure loss, increased compressor run time, reduced system performance, oil accumulation around components, or deteriorated sealing materials discovered during maintenance inspections.

Replacement intervals vary depending on compressor design, operating conditions, maintenance practices, and the specific component being serviced. Many gaskets, O-rings, and seals are replaced during scheduled maintenance, rebuilds, or component repairs. Always follow the maintenance recommendations provided by the compressor manufacturer for your specific equipment.

While all three components are used to prevent leakage, they serve different purposes within the compressor system. A gasket is typically a flat sealing material placed between two mating surfaces. An O-ring is a circular elastomer seal designed to fit within a groove and create a pressure-tight connection. A seal is a broader term that may refer to shaft seals, lip seals, mechanical seals, or other components used to prevent air or fluid leakage in moving and stationary applications throughout the compressor.

The correct replacement component can typically be identified using the compressor manufacturer, model number, serial number, component information, dimensions, or OEM part number. Selecting the proper sealing component helps ensure compatibility, proper fit, and reliable compressor operation.
