When a seal, gasket, or valve seat fails under harsh operating conditions, you absorb costly downtime, cleanup, and safety risks. At DHPP, we engineer custom valve seats, Teflon seals, gaskets, and diaphragms to match the exact chemistry, pressure, and thermal demands of your specific application.
Formed from virgin PTFE and high-performance filled PTFE blends, our sealing components deliver complete chemical inertness, low friction, and reliable performance across cryogenic, steam, and high-heat environments.
✓ Engineered for the Chemistry, Not Just the Shape: Precision-selected material grades rated for standard chemical processing, petroleum, cryogenic, chlorine, steam, and abrasive media.
✓ Every Valve & Seal Profile Covered: Custom ball, butterfly, gate, plug, and check valve seats, alongside custom shaft seals, Teflon gaskets, and flexible diaphragms.
✓ Built for Extreme Operating Environments: Chemically inert, low-friction PTFE formulations that maintain elasticity at sub-zero temperatures and structural integrity under high heat.
✓ 30+ Years of Proven Reliability: Manufactured in our Dover, Ohio facility since 1990, trusted by plant managers who cannot afford seal failure.
Partner with Dover High Performance Plastics for high-performance sealing solutions designed to outlast standard parts in harsh operating conditions.
