Until now o ring standards have left a gap between the 1 8 and 3 16 nominal cross sections.
O ring cross section shapes.
In stock and ready to ship.
Wherever possible use a backup ring on each side of the o ring.
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.
Of an o ring gland is primarily influenced by the diameter of the mating surface.
It is a loop of elastomer with a round cross section designed to be seated in a groove and compressed during assembly between two or more parts creating a seal at the interface.
By absorbing the tolerance stack up between connected surfaces in both dynamic and static applications it acts as a compact and reliable sealing device.
Buna n and viton o rings can be used for sealing valves faucets flanges engines and more.
An o ring also known as a packing or a toric joint is a mechanical gasket in the shape of a torus.
D rings can be manufactured to standard o ring sizes as well as custom sizes for specific applications.
Nominal cross section o rings.
900 series o rings feature a round cross section.
Rectangular cross section features a split for easy installation.
O ring is a simple and versatile ring shaped sealing device with a circular cross section.
Fda and nsf61 compliant o rings feature a round cross section and medium hardness.
Although the cross section of the o ring is seen as fairly arbitrary there are some distinct advantages to either a larger or smaller cross section o ring.
Choose from our selection of metric o rings including oil resistant buna n o rings high temperature silicone o rings and more.
An o ring also known as a packing or a toric joint is a mechanical gasket in the shape of a torus.
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.
Each features a round cross section.
Please contact us if you are looking for a size not shown in the 5 32 group.
For low pressure applications the combination of a low modulus material and small cross section can help to reduce friction.
The o ring may be used in static applications or in dynamic applications where there is relative motion between.
It is used to prevent the loss of fluid or gas.
