Pipe-Lok Vales & Fittings Company delivers precision-engineered instrumentation fittings and valves trusted for reliability, safety, and performance in industrial applications with a strong focus on engineering excellence and quality control.
PTFE (Polytetrafluoroethylene) offers outstanding chemical inertness, a very low coefficient of friction and excellent performance across a wide temperature range, making it well suited for VCR sealing components and fittings in ultra-pure and highly corrosive fluid systems.
Fluoropolymer resin composed of repeating tetrafluoroethylene units, offering near-universal chemical resistance and non-reactivity.
| Element | Weight Percentage (%) |
|---|---|
| Polymer Composition | (C2F4)n, virgin PTFE resin |
| Purity | 99.5% min virgin material |
| Fillers | None (unfilled virgin grade) |
*Composition limits are as per the applicable ASTM/ASME/UNS specification; actual limits may vary depending on product form.
PTFE retains flexibility and chemical resistance across an extremely wide service temperature range with minimal moisture absorption.
