PTFE tape used for different sized fittings PTFE tape for natural gas. There are two US standards for determining the quality of any thread seal tape. MIL-T-27730A (an obsolete military specification still commonly used in industry in the US) requires a minimum thickness of 3.5 mils and a minimum PTFE purity of 99%. [3]
A compression fitting 15 mm isolating valve. A compression fitting is a fitting used in plumbing and electrical conduit systems to join two tubes or thin-walled pipes together. . In instances where two pipes made of dissimilar materials are to be joined (most commonly PVC and copper), the fittings will be made of one or more compatible materials appropriate for the connect
Rulon A has a 1000 fold increase in wear resistance as compared to PTFE. However, it machines much like PTFE. It can also be moulded, extruded, skived, stamped, and hot and cold formed. Below is a table of properties pertaining to Rulon AR, but note that the other types of Rulon have similar properties. [1]
Teflon is a brand of PTFE, often used as a generic term for PTFE. The metallic substrate is roughened by abrasive blasting, then sometimes electric-arc sprayed with stainless steel. [8] [9] The irregular surface promotes adhesion of the PTFE and also resists abrasion of the PTFE. [10] Then one to seven layers of PTFE are sprayed or rolled on.

Polytetrafluoroethylene (PTFE), better known by its trade name Teflon, has many desirable properties which make it an attractive material for numerous industries. It has good chemical resistance, a low dielectric constant, low dielectric loss, and a low coefficient of friction, making it ideal for reactor linings, circuit boards, and kitchen utensils, to name a few applications.
