We also accept customized orders.
Product Description
Superior High-Temperature Resistance
Crafted from premium high-temperature resistant rubber materials, including silicone rubber, viton (fluorocarbon rubber), ethylene propylene diene monomer (EPDM) and nitrile rubber, our flat gaskets exhibit exceptional thermal stability. Depending on material selection, the gaskets can withstand continuous operating temperatures ranging from -40℃ to 280℃, with short-term resistance to peaks up to 320℃. This wide temperature range ensures stable sealing in high-heat scenarios such as steam valves, thermal oil pipelines, boiler valves and industrial furnaces, effectively preventing medium leakage caused by material aging, deformation or cracking under extreme temperatures.
The rubber materials undergo specialized vulcanization treatment, which enhances their thermal conductivity and structural integrity. Unlike ordinary rubber gaskets that harden, brittle or soften under high temperature, our products maintain consistent elasticity and sealing pressure, ensuring tight contact between the valve cover and valve body even after long-term high-temperature operation.
Customized Design For Precise Fit
We understand that valve covers come in diverse sizes, shapes and specifications across different industries and equipment models. Our gaskets are fully customized to match the exact dimensions and technical requirements of your valve covers. Using advanced CNC cutting and molding technology, we achieve precise tolerances (up to ±0.02mm) to ensure a perfect fit, eliminating gaps that may lead to leakage.
Beyond size customization, we also offer tailored material selection based on your specific operating medium. For instance, viton gaskets are recommended for chemical valves handling corrosive media such as acids, alkalis and solvents; EPDM gaskets are ideal for water, steam and neutral media; while silicone rubber gaskets excel in food, pharmaceutical and high-purity applications. Our engineering team works closely with customers to analyze operating parameters, including temperature, pressure, medium type and vibration intensity, to provide optimal material and structure solutions.
Wide Industrial Applications
Our customized high-temperature flat rubber gaskets are widely used in valve covers across multiple industries, including petroleum and petrochemical, power generation (thermal power, nuclear power), chemical processing, metallurgy, pharmaceutical, food and beverage, and automotive manufacturing. Whether for heavy-duty industrial valves in refineries or precision valves in pharmaceutical production lines, our gaskets provide consistent and reliable sealing performance, complying with industry standards such as ISO, ASTM and DIN.
Quality Assurance & Environmental Compliance
We adhere to strict quality control standards throughout the production process. From raw material inspection (testing for thermal stability, elasticity and chemical composition) to molding, vulcanization and finished product testing, each step is monitored to ensure product consistency and performance. Our gaskets are free of harmful substances such as heavy metals and volatile organic compounds (VOCs), meeting environmental and food safety requirements for sensitive industries.
Backed by professional technical support and after-sales service, we provide customers with comprehensive solutions, including gasket selection guidance, sample testing, batch production and on-site installation advice. Our goal is to deliver customized sealing products that enhance the reliability and efficiency of your valve systems, helping you reduce operational risks and improve productivity.
EPM Washer
EPM (Ethylene Propylene Monomer) washers are rubber gaskets made from ethylene propylene rubber, known for excellent weather resistance, ozone tolerance, and heat stability (-40°C to 150°C). They resist water, weak acids, alcohols, and aging, maintaining elasticity under dynamic stress. Sizes vary to match bolts/nuts, with standards aligning with industrial sealing specs.
Applications:
Automotive: Seal door/window edges, engine bay hoses, or battery compartments (resist engine heat and weathering).
Plumbing: Gasket pipes, valves, or fittings to prevent leaks in water/fluid systems.
Electronics: Waterproof enclosures for outdoor sensors, junction boxes, or LED fixtures.
Mechanical Equipment: Dampen vibrations and seal gaps in pumps, compressors, or HVAC units.
Outdoor Infrastructure: Seal solar panel mounts, streetlight housings, or signage (withstand UV and temperature swings).
Their durability in harsh environments makes EPM washers ideal for sealing, damping, and protecting against moisture/weather in diverse industries.
