Rain Caps
Overview
Parker Fabrication manufactures heavy-duty exhaust rain caps designed to protect engines and exhaust systems operating in demanding environments. Installed at the termination point of vertical exhaust stacks, rain caps prevent water, debris, and foreign material from entering the exhaust system when equipment is not in operation.
Function and Benefits
Rain caps serve as a simple but critical protective component for exhaust systems used in construction, mining, agricultural, marine, and industrial equipment. When the engine is off, the cap closes to shield the exhaust opening. When exhaust pressure is present, the cap opens automatically to allow unrestricted airflow.
Key Benefits
- Prevents rainwater and moisture from entering exhaust systems
- Reduces corrosion and internal component damage
- Helps maintain proper airflow and engine performance
- Protects against debris, dust, and foreign objects
- Extends exhaust system life and reduces maintenance costs
Rain caps are especially important for equipment exposed to outdoor conditions, where moisture intrusion can lead to corrosion, clogging, or system failure over time.
Applications
- Construction and mining equipment
- Agricultural machinery
- Industrial engines and generators
- Marine exhaust systems
- Forestry and heavy-duty equipment
Expansion Joints
Overview
Parker Fabrication exhaust expansion joints are engineered to absorb thermal expansion, vibration, and movement within exhaust and piping systems. These components protect exhaust assemblies by reducing stress caused by temperature changes and engine movement.
Function and Benefits
Exhaust systems experience extreme heat cycles during operation. As temperatures rise and fall, metal piping expands and contracts. Expansion joints provide flexibility within the system, preventing cracking, fatigue, and premature failure.
Key Benefits
- Absorbs thermal expansion and contraction
- Reduces vibration transmitted through exhaust systems
- Minimizes stress on piping, manifolds, and connected components
- Improves system durability and reliability
- Allows for slight misalignment during installation and operation
Expansion joints are commonly manufactured from high-temperature stainless steels and alloys capable of withstanding extreme operating conditions while maintaining flexibility and structural integrity.
Applications
- Diesel engine exhaust systems
- Power generation equipment
- Mining and construction machinery
- Marine propulsion systems
- Industrial processing equipment
High Temperature Gaskets
Overview
Parker Fabrication high temperature gaskets are designed to create reliable seals between exhaust system components operating under high heat and pressure conditions. These gaskets prevent exhaust leaks while maintaining system efficiency and safety.
Function and Benefits
High temperature exhaust systems require materials capable of maintaining sealing performance under extreme heat cycles. Parker Fabrication gaskets are manufactured using materials such as reinforced graphite, composite fiber, and high-temperature non-asbestos material depending on application requirements.
Key Benefits
- Provides a secure seal between exhaust flanges and components
- Prevents exhaust gas leaks
- Withstands extreme temperatures and pressure changes
- Maintains system efficiency and emissions performance
- Available in custom sizes and materials for OEM applications
Many industrial exhaust gasket materials are engineered for temperatures approaching or exceeding 1,800 degrees Fahrenheit, making them suitable for heavy-duty engine and industrial applications.
Applications
- Exhaust manifold connections
- Flanged piping systems
- Turbocharger connections
- Industrial engine exhaust assemblies
