PTFE Solid Discs

A solid disc provides a continuous contact layer across its diameter. It can sit between an electrical assembly and a support, line a small contact area or separate compatible process media from an underlying surface.

The hole-free geometry distinguishes it from a washer. Adding a center bore, offset hole or slot changes the part drawing and the load path; describe those features as a custom component rather than altering the standard disc reference.

Thin discs can curl during handling and need flat support in the assembly. Thicker discs add axial separation and handling stiffness, but sustained clamp force still produces deformation in PTFE.

Define the required flatness and edge condition alongside diameter and thickness. For a sealing contact, identify the supported face and compression method. For a spacer, use the loaded assembly height rather than assuming the free thickness stays unchanged under force.

A circular blank can be the starting point for a machined insulating pad, seat or cover. The supplied photo range includes thick machining blanks as well as flat discs; the standard-size table below refers specifically to the listed D × T combinations.

A disc used across an opening needs a supporting and retaining structure designed for that load. Diameter and thickness alone do not assign a pressure rating. Include the support diameter, fluid, temperature and pressure in a cover or closure inquiry.
