Frequently Asked Questions (FAQs)
1. What makes PTFE gaskets superior to other materials?
PTFE gaskets offer exceptional chemical resistance to nearly all substances, outstanding temperature range (-328°F to 500°F), extremely low friction, and excellent sealing properties. They’re also FDA compliant and non-contaminating.
2. What types of filled PTFE gaskets do you offer?
We manufacture gaskets using various PTFE compounds including glass-filled for improved rigidity, carbon-filled for better wear resistance, and bronze-filled for enhanced thermal conductivity. Each filler is selected based on specific application requirements.
3. Are your PTFE gaskets FDA compliant?
Yes, our PTFE gaskets are available in FDA-compliant materials meeting 21 CFR 177.1550 requirements, making them ideal for food contact, pharmaceutical, and medical applications.
4. What are typical PTFE gasket lead times?
Standard PTFE gaskets typically ship within 5-7 business days. Custom sizes or specialized compounds may require additional time. Rush orders can be accommodated for critical applications.
5. Can you manufacture custom PTFE gasket designs?
Yes, we can produce custom PTFE gaskets to your exact specifications using our advanced manufacturing capabilities, including special sizes, shapes, and filled PTFE compounds for specific performance requirements.
