FAQs
Can your seals withstand 200–230°C continuous heat?
Yes, Silicone, EPDM & PTFE-laminated compounds are validated for extreme temperatures.
Do your seals maintain compression in steam cycles?
Yes, our elastomers resist compression-set under autoclave/CIP/SIP conditions.
Can inflatable seals compensate for uneven door surfaces?
Yes, they expand uniformly and seal warped/misaligned doors.
Do you offer FDA-grade materials for sterilization?
Yes, FDA-compliant Silicone/EPDM available when required.
How do your seals resist chemical exposure at high heat?
PTFE-laminated materials provide excellent chemical stability.
Can you supply large-diameter autoclave seals?
Yes, we manufacture seamless vulcanized rings for industrial autoclaves.
