Until now o ring standards have left a gap between the 1 8 and 3 16 nominal cross sections.
Rectangular cross section o rings.
Rings for claw clamp and bolt together high vacuum fittings for stainless steel tubing.
Rectangular cross section features a split for easy installation.
These ptfe backup rings resist harsh chemicals such as acetone fluorinated solvents methanol and many acids.
They cover more surface than round profile o rings for a better seal in static applications such as hose pipe and faucet connections.
Wherever possible use a backup ring on each side of the o ring.
In de signing this new group of o rings we left spacing in the part numbers to allow us to add additional sizes should they be required.
Ptfe backup o rings are designed to be used in conjunction with standard o rings to help prevent extrusion in high pressure applications or where extrusion gaps are excessive.
The diagram shows exactly where these dimensions are to be found.
O rings are actually really easy to measure.
Wherever possible use a backup ring on each side of the o ring.

Nominal cross section o rings.
For those times when hardware real estate is at a premium and we simply cannot increase the inside corner radii to the desired size an alternative option is the o seal.
All you need to do is measure the internal diameter id or outside diameter od and the width or cross section c s of the o ring.
