What Are Screen Gaskets?
Screen gaskets are specialised gaskets that incorporate a mesh screen or filter within their sealing structure. Unlike conventional gaskets that solely provide sealing, screen gaskets also remove particulates, debris, or impurities from the process stream while maintaining a secure and leak-proof seal.
These gaskets are commonly used in piping systems, pumps, filtration units, and processing equipment where contaminant removal and system protection are essential.
Benefits of Screen Gaskets
Screen Gaskets are essential for process efficiency, equipment protection, and product quality. Stephens Gaskets’ screen gaskets are manufactured to deliver superior sealing and filtration while maintaining industry compliance.
1. Dual Functionality – Sealing and Filtration
- Combines leak-proof sealing with contaminant removal in a single component.
- Reduces the need for separate gaskets and inline filtration, simplifying system design.
2. Enhanced Equipment Protection
- Filters metal particles, debris, and sediment, preventing clogging and damage to pumps, valves, and spray nozzles.
- Minimises downtime and maintenance by keeping systems clean and running efficiently.
3. Chemical and Corrosion Resistance
- Withstands harsh chemicals, high temperatures, and aggressive fluids, ensuring long-term durability.
- Available in PTFE, stainless steel, and high-grade elastomers for superior resistance.
4. Sanitary and Hygienic Design
- Meets FDA, USP Class VI, and 3A Sanitary Standards for food and pharmaceutical applications.
- Non-porous surfaces prevent bacterial growth and ensure clean processing.
5. Customisable for Specific Applications
- Available in various mesh sizes, materials, and thicknesses to match specific filtration and sealing requirements.
- Tailored solutions for unique pipeline connections, specialty processing, and high-precision applications.
6. Reduced Maintenance and Downtime
- Easily replaceable and cleanable without system disassembly.
- Prevents unexpected failures and costly repairs by filtering out damaging contaminants.
Applications of Screen Gaskets
Stephens Gaskets’ screen gaskets are engineered for a wide range of industries where sanitation, contamination control, and filtration are paramount.
- Used in juices, dairy, sauces, and beverage production to prevent pulp, seeds, or unwanted solids from contaminating the final product.
- Installed in pumps, valves, and sanitary pipelines to ensure compliance with food safety standards.
- Maintains purity in sterile processing and liquid filtration, ensuring compliance with FDA and USP Class VI standards.
- Used in injectables, vaccines, and sterile filtration systems where even the smallest contaminant can impact product integrity.
- Filters chemical particulates to prevent equipment damage or contamination during chemical manufacturing and refining.
- Provides corrosion-resistant sealing in environments handling highly reactive fluids and aggressive chemicals.
- Ensures particle-free filtration in municipal water processing, desalination plants, and industrial filtration systems.
- Protects pumps, valves, and reverse osmosis systems from sediment buildup.
- Used in fuel pipelines, lubrication systems, and refinery equipment to filter out metal debris and particulates.
- Helps prevent blockages in high-pressure oil and gas transmission systems.
- Filters coolants, hydraulic fluids, and lubricants in industrial equipment to enhance machinery lifespan and efficiency.
- Reduces wear and tear in precision spray nozzles and high-tolerance fluid systems.
- Protects hydraulic and fuel injection systems in aircraft and vehicles by removing harmful contaminants.
- Ensures uninterrupted flow in high-performance automotive and aviation fuel systems.
Materials Used in Screen Gasket Manufacturing
At Stephens Gaskets, we use only high-performance materials to ensure our screen gaskets withstand the most demanding environments.
1. Stainless Steel Mesh (304 & 316 Grade)
- Provides superior strength and corrosion resistance for chemical, oil, and food processing applications.
- Available in various mesh sizes to suit different filtration requirements.
2. PTFE (Polytetrafluoroethylene)
- Chemically inert and non-reactive, making it ideal for pharmaceutical, biotech, and aggressive chemical applications.
- Withstands extreme temperatures and highly corrosive environments.
3. Silicone and Platinum-Cured Silicone
- Complies with food and pharmaceutical-grade requirements.
- Resistant to heat, steam, and sterilisation processes.
5. EPDM (Ethylene Propylene Diene Monomer)
- Excellent weather and ozone resistance, making it ideal for water treatment and sanitary applications.
- Provides a flexible and reliable seal in piping and filtration systems.
6. Viton® (FKM – Fluorocarbon Elastomer)
- Handles high temperatures, oils, and aggressive chemicals in industrial and petrochemical applications.
- Offers superior compression set resistance, ensuring long-term sealing performance.
Common Challenges in Screen Gasket Applications & How Stephens Gaskets Solves Them
1. Clogging and Pressure Drop Issues
- Fine mesh screens can become blocked with debris, affecting flow rates.
- Stephens Gaskets provides optimised mesh sizing and self-cleaning screen options to reduce clogging.
2. Material Degradation in Harsh Environments
- Exposure to high temperatures and corrosive chemicals can break down inferior materials.
- We offer high-performance materials like PTFE, Viton®, and stainless steel to ensure longevity.
3. Compatibility and Fitment Issues
- Poorly sized gaskets may lead to leaks or inefficient filtration.
- Stephens Gaskets provides custom-fit designs to match exact system specifications.
4. Frequent Maintenance and Downtime
- Traditional filtration solutions require constant monitoring and cleaning.
- Our durable, long-life screen gaskets reduce maintenance intervals and downtime.
