Category | Usage Scenarios | Characteristics | Advantages | Disadvantages |
---|---|---|---|---|
Silicone Seals | High-temperature machinery, chemical plants | Withstands 250°C (▲25% over Base, ASTM D1248), resists 50+ chemicals (ASTM D543) | Flexible for irregular surfaces, Advanced version offers 40% better chemical resistance (▲) | Higher cost than standard rubber; less rigid for heavy compression needs |
EPDM Seals | Automotive, outdoor equipment | Resists -40°C to 120°C (ISO 188), UV-resistant for prolonged outdoor use | Cost-effective, durable in weathering conditions | Limited chemical resistance (e.g., oils, solvents) |
Nitrile Seals | Oil/gas systems, automotive engines | Resists oils/fuels (ASTM D2000), operates -25°C to 100°C | Excellent oil resistance, affordable for industrial fluids | Stiffer, less flexible than silicone; not UV-resistant |
Neoprene Seals | Marine, general industrial | Withstands -30°C to 90°C (ASTM D2000), ozone/UV-resistant | Versatile for moderate environments, moderate cost | Lower chemical resistance than specialized materials (e.g., acids) |
Viton Seals | Harsh chemical labs, aerospace | Resists 200+ chemicals (ASTM F739), up to 250°C (▲ vs silicone Base) | Superior to silicone in corrosive environments (e.g., acids, solvents) | Expensive, less flexible; requires precise installation |
Standard Rubber Seals | General sealing, low-cost applications | Operates -20°C to 80°C (ISO 37), basic chemical resistance | Affordable, widely available for non-extreme conditions | Fails in high temps/chemicals; short lifespan in harsh environments |
⭐⭐⭐⭐⭐ James Carter - Manufacturing Plant
"We’ve been using the JiuYan Pro Model Nitrile Seals in our hydraulic systems for six months now, and the difference is undeniable. These seals handle constant exposure to oil and high pressure without degrading—something our old rubber gaskets couldn’t withstand beyond two months. The precision thickness option ensured a perfect fit, and downtime due to leaks has dropped significantly."Purchase Date: February 2025 | Usage Period: 6 months
⭐⭐⭐⭐⭐ Emily Tran - Home User
"I bought the Base Model Silicone Seals to replace the worn gasket on my high-end thermos and coffee maker. The transparent design made it easy to confirm proper seating, and the seal is airtight. Even after three months of daily use, there’s no warping or odor retention. Knowing it’s FDA-approved gives me peace of mind when handling hot beverages."Purchase Date: November 2024 | Usage Period: 4 months
⭐⭐⭐⭐☆ Marcus Lee - Auto Repair Shop
"Installed the Advanced Model EPDM Seals on several older vehicles with exhaust and HVAC issues. Their ozone and UV resistance really shines—especially on cars parked outdoors. They’re not as flexible as silicone, but for exterior applications where weathering is a concern, this is the best mid-range option we’ve tested. Only docked one star because custom slotting took longer than expected to process."Purchase Date: January 2025 | Usage Period: 5 months
⭐⭐⭐⭐⭐ Diana Patel - Commercial HVAC Installer
"On a recent job retrofitting rooftop units, we needed reliable seals that could endure temperature swings from -30°C to over 200°C. The JiuYan silicone compression seals were the only ones on the market that met both the thermal and chemical resistance specs. The ability to custom-cut them on-site saved hours. Now I specify these by default for all high-temp applications."Purchase Date: April 2025 | Usage Period: 2 months
⭐⭐⭐⭐⭐ Andrei Petrov - Industrial Facility
"We operate in a corrosive environment with frequent acid exposure. After switching to the JiuYan silicone seals, we’ve seen zero degradation in over seven months—compared to weekly replacements with standard rubber. The 40% improved chemical resistance claim holds true. These aren’t cheap, but they’ve already paid for themselves in reduced maintenance and safety compliance."Purchase Date: August 2024 | Usage Period: 8 months

Dr. Rebecca Liu - Senior Materials Engineer
"Silicone’s performance in extreme thermal cycles and its inert, food-safe properties make it the gold standard for modern sealing applications. JiuYan’s molded silicone seals stand out due to their consistency in Shore hardness and purity—critical for both consumer appliances and industrial systems. For any application above 150°C, I recommend silicone over EPDM or nitrile without hesitation."
Carlos Mendez - Automotive Sealing Specialist
"In engine compartment sealing, material choice is everything. While nitrile still has its place, I’m increasingly specifying high-temp silicone—like JiuYan’s Base Model—for intake manifolds and turbo housings. Its resilience under thermal cycling and resistance to coolant mixtures outperforms traditional options. The transparency feature also aids diagnostics during service, reducing labor time."
