✨ Key Advantages of Our PTFE Seal Balls
Exceptional Chemical Stability
Resists corrosion from most chemicals, acids, and solvents—perfect for harsh industrial environments.
Superior Sealing Performance
Smooth, burr-free surface ensures tight, leak-proof seals for diaphragm pumps and valves.
Wide Temperature Tolerance
Operates reliably from -190℃ to +280℃, adapting to extreme hot/cold working conditions.
High Lubrication & Non-Stick
Reduces friction in moving parts, extending the lifespan of pumps and valve systems.
🏭 Industrial Applications for PTFE Spheres
Our white PTFE seal balls are indispensable in diverse industries, including:
- Chemical processing (reactors, pipelines, storage tanks)
- Mechanical engineering (diaphragm pumps, hydraulic systems)
- Valve manufacturing (ball valves, check valves, control valves)
- Electronics & electrical appliances (insulation, high-temperature components)
- Aerospace & automotive (precision sealing in extreme environments)
❓ FAQs About PTFE Diaphragm Pump Seal Balls
What diameter sizes do these PTFE spheres come in?
We offer white PTFE seal balls in 23 precise diameters: 3mm, 4mm, 5mm, 6.35mm, 7mm, 8mm, 9.5mm, 10.5mm, 12.7mm, 15mm, 16mm, 18mm, 20mm, 22mm, 25mm, 30mm, 32mm, 35mm, 40mm, 45mm, 50mm, 57mm, and 63mm.
Can these PTFE balls be used in food-grade applications?
Yes! PTFE is FDA-approved for food contact. Our PTFE spheres are safe for use in food processing equipment (pumps, valves) where hygiene and chemical resistance are critical.
How does PTFE compare to other sealing materials like rubber?
PTFE outperforms rubber in chemical resistance, temperature tolerance (-190℃ to +280℃), and longevity. It’s non-stick and low-friction, making it better for high-wear industrial sealing vs. rubber.
Are these PTFE seal balls suitable for high-pressure diaphragm pumps?
Absolutely! Our solid PTFE spheres are engineered for high-pressure applications. Their rigid, durable construction maintains sealing integrity even in demanding pump systems.
Do you offer bulk discounts for large orders of PTFE balls?
Yes! For bulk purchases of PTFE diaphragm pump seal balls, contact our customer service team. We provide custom discounts based on order quantity and diameter requirements.
