Gaskets and Seals

Description

Compressor Gaskets & Sealing Components

Depending on the compressor design and application, the replacement range can include:

• Compressor gaskets
• Air-end gaskets
• Housing gaskets
• Flange gaskets
• Cylinder gaskets
• End-cover gaskets
• Oil system gaskets
• Cooler gaskets
• Separator gaskets
• Valve gaskets
• Pipe and connection gaskets
• Shaft seals
• Oil seals
• Mechanical seals
• Lip seals
• O-rings
• O-ring kits
• Seal kits
• Complete compressor gasket and seal kits

The exact components required depend on the compressor make, model, configuration, and maintenance scope.

Importance of Gaskets & Seals

Compressor systems operate under pressure and may contain lubricating oil, compressed air, or process gases. Proper sealing helps maintain the intended operating conditions of the equipment.

Worn or damaged sealing components can contribute to:

• Air leakage
• Oil leakage
• Pressure loss
• Reduced compressor efficiency
• Contamination
• External leakage
• Internal bypass
• Increased maintenance requirements
• Abnormal compressor operation

Replacing sealing components during an appropriate maintenance or overhaul interval can help restore the integrity of the compressor assembly.

Gaskets for Screw Compressor Air Ends

The screw compressor air end contains precision-machined components operating under pressure and temperature.

Gaskets may be used at various interfaces within the compressor assembly, depending on the specific design.

Potential applications include:

• Air-end housing
• End covers
• Oil connections
• Cooler connections
• Separator assemblies
• Flanged connections
• Serviceable compressor components

The gasket profile, thickness, dimensions, and material should be matched to the original equipment requirements.

Shaft Seals & Oil Seals

Shaft sealing components are used to help prevent lubricating oil or process fluid from escaping along rotating shafts.

Depending on the compressor design, replacement sealing components may include:

• Shaft seals
• Oil seals
• Lip seals
• Rotary seals
• Mechanical sealing components
• Seal assemblies

Correct selection depends on shaft dimensions, rotational speed, operating temperature, lubricant, pressure, and compressor design.

O-Rings

O-rings are commonly used as static or dynamic sealing elements within compressor systems.

They may be found in:

• Valve assemblies
• Pipe connections
• Oil circuits
• Cooler connections
• Filter housings
• Separator assemblies
• Compressor housings
• Serviceable components

O-ring material must be selected according to the operating medium, temperature, pressure, and chemical compatibility.

Gasket & Seal Kits

For compressor servicing and overhaul applications, Aegis Projects can supply gasket and seal kits containing multiple sealing components required for a defined maintenance scope.

A kit may include:

• Gaskets
• O-rings
• Oil seals
• Shaft seals
• Flange seals
• Housing seals
• Other application-specific sealing components

The contents of a kit depend on the compressor model and the required service or overhaul procedure.

Materials

Gaskets and seals can be manufactured from different materials depending on the application.

Potential material categories may include:

• Elastomeric materials
• Nitrile-based materials
• Fluoroelastomer materials
• PTFE-based materials
• Graphite-based materials
• Fiber-based gasket materials
• Metallic gasket materials
• Composite sealing materials

The appropriate material must be selected according to the compressed medium, oil compatibility, operating temperature, pressure, chemical exposure, and equipment manufacturer’s requirements.

Applications

Gaskets and seals are used across a wide range of compressor and industrial applications, including:

• Rotary screw compressors
• Oil-injected screw compressors
• Oil-free screw compressors
• Industrial air compressors
• Compressor air ends
• Compressed air systems
• Process gas compressors
• Gas compression packages
• Manufacturing plants
• Chemical plants
• Petrochemical facilities
• Oil and gas installations
• Power plants
• Pharmaceutical industries
• Food and beverage facilities
• General industrial utilities

Replacement & Maintenance Applications

Gaskets and seals are commonly replaced during:

• Preventive maintenance
• Compressor servicing
• Compressor overhaul
• Air-end refurbishment
• Leak repair
• Seal replacement
• Bearing replacement
• Cooler servicing
• Valve servicing
• Compressor rebuilds
• Equipment refurbishment

Replacing seals whenever required during an overhaul can help avoid premature leakage after the equipment is returned to service.

Selecting the Correct Gasket or Seal

Accurate identification is important because sealing components can vary significantly between compressor models.

Recommended information includes:

Providing the compressor nameplate, existing part number, component dimensions, or clear photographs can assist with identification.
