PTFE Tape Cross-Reference Guide: Match Your Existing Specification to a Lanmar Equivalent
Finding an equivalent PTFE tape for an existing specification takes time. This cross-reference guide helps engineers, purchasing teams, and maintenance professionals quickly match commonly used tape part numbers from major manufacturers to equivalent Lanmar tapes.
The guide covers PTFE coated fiberglass tape, PTFE film tape, UHMW tape, and other high-temperature pressure sensitive tapes. Lanmar tapes are built to meet or exceed the performance of widely used products, so you can switch suppliers without changing your process or requalifying materials.
Cross-referenced manufacturers include 3M, Taconic, Saint-Gobain, and AFC. If your current part number is not listed, our team can cross-reference it and recommend a compatible alternative.
