Ameri-lon PTFE Material

American Seal and Packing offers a line of products utilizing PTFE in both Gasket Materials and Braided Pump / Valve Packing.

Ameri-lon Pump and Valve Packing

Ameri-lon Valve and Pump Packing offers the best of several worlds.  It has a 0-14 PH range allowing it to be used in most chemical applications*.  It also has a temperature range of up to 500 F.  Because it is made of a roughly 60/40 ratio of PTFE to graphite, it does not have the cold flow and sleeve/shaft eating characteristics of a straight PTFE packing.  Ideal for a wide range of applications at an affordable price.  Ameri-lon is our most universal packing.

* This is to be used as a general guide only.  All applications should be considered individually based on the temperature, pressure, media being sealed, Ph, gasket dimensions, torque load, bolt size and any other factor effecting the gasket.  For assistance in determining the suitability of an application contact our technical staff at American Seal & Packing. No application should be undertaken by anyone without independent study and evaluation for suitability. Never use more than one gasket in one flange joint, and never reuse a gasket.
