Machined PTFE Long-Lasting Sealing — Bost
Product Overview
Bost Machined PTFE Long-Lasting Sealing delivers reliable, long-term sealing performance for industrial equipment. Made from high-purity PTFE and precision-machined to tight tolerances, these seals offer exceptional chemical resistance, low friction, and wide temperature range stability. Designed for applications such as valves, pumps, compressors, and custom assemblies, the product ensures leak-free operation and reduced maintenance intervals.
Key Features
- Exceptional chemical resistance against acids, bases and most solvents
- Low friction and non-stick surface for smooth operation and reduced wear
- Wide operating temperature range suitable for high- and low-temperature environments
- Precision machining for accurate dimensions and consistent sealing performance
- Long service life that lowers downtime and maintenance costs
Technical Advantages
Bost specializes in advanced engineering plastics and material modification. Our machined PTFE seals benefit from dedicated R&D and production teams, ensuring each part meets performance and dimensional specifications. We can tailor hardness, thickness, and finishing to match flange, shaft, or housing geometries. The seals are compatible with steel, plastic, and rubber interfaces, enabling composite solutions where required.
Typical Applications
- Valve seats and stem seals
- Pump seals and bushes
- Bearings and sliding surfaces
- Custom gaskets and precision components for chemical, petrochemical, food, and pharmaceutical industries

FAQ
What is the minimum order quantity (MOQ)? Do you support small-batch trial production?
The MOQ for standard products is ≥100kg. We support small-batch trial production (as low as 20kg) and provide mold testing reports and performance data feedback.
How do I select the appropriate engineering plastic grade for my product?
Selection should be based on parameters such as load conditions (e.g., pressure/friction), temperature range, medium contact (e.g., oil/acid), and regulatory requirements (e.g., FDA/RoHS). Our engineers can provide free material selection consulting and sample testing.
Can Bost customize modified plastics with special properties?
Yes! We offer modification services such as reinforcement, flame retardancy, conductivity, wear resistance, and UV resistance, for example:
• Adding carbon fiber to enhance stiffness
• Reducing the coefficient of friction through PTFE modification
• Customizing food-grade or medical-grade certified materials
What is the delivery lead time? Do you offer global logistics?
Standard products: 5–15 working days; custom modifications: 2–4 weeks. We support global air/sea freight and provide export customs clearance documents (including REACH/UL certifications).
