How do you measure seals?
The dimensions that need to be measured on a seal are the ID, OD and the width, or the thickness. The following is a general guideline for measuring some of the most basic seal designs. The following examples are general guidelines and are not all inclusive.
Oil Seals Identifying the manufacturer of an oil seal can be difficult, however many manufacturers stamp the dimensions on the seal. The numbers shown on the seal indicate the size. 70 90 10 shows the shaft of 70mm, the bore is 90mm and the width or height is 10mm. Some seals have different sealing lip configurations, such as single or double.
O-Rings Two dimensions are also needed for measuring o-rings correctly. The inside diameter and the cross section (thickness) of the o-ring.
There are too many sealing types and variations to address all sealing configurations, please call our seal specialists at our office for further assistance.

What is a PTFE Seal?
A PTFE seal is a synthetic fluoropolymer of tetrafluoroethylene with numerous applications. PTFE is a fluorocarbon solid, as it is a high-molecular weight compound consisting wholly of carbon and fluorine. PTFE is hydrophobic: neither water nor water-containing substances wet PTFE.
PTFE can be loaded with glass, carbon, graphite, bronze, MOS2 or any of the other fillers available to enhance the performance of your seals.
These PTFE materials are used in all industries and many different types of seals. Typical applications are rod and piston seals for fluid power cylinders, o-rings, lantern rings, SS spring loaded u-cups, PTFE lipped oil seals and many special engineered seals.
