This tool uses standard geometry and a simple stretch adjustment model.
The calculator compares squeeze-based depth with fill-based geometry. That helps you see whether your selected angle supports the intended seal packing level.

A triangular O ring groove calculator helps you estimate sealing space before machining starts. Groove geometry changes how the seal deforms. Depth controls squeeze. Width and angle control gland area. Stretch changes the installed cross section. These variables must work together. A poor match can create leakage, wear, or difficult assembly.
This calculator focuses on practical groove planning. It estimates installed seal area after stretch. It then finds target groove area from the selected fill value. Next, it calculates groove depth from squeeze. It also checks the groove area created by your chosen triangular angle. This comparison is useful because one design choice can conflict with another. The result section shows that conflict clearly.
The output includes groove depth, top width, target groove area, actual fill, and estimated groove volume. These values help when reviewing machining limits, assembly space, and seal compression. The design note explains whether the selected angle is close to the requested fill target. That message helps you decide if you should change depth, angle, or both.
You can use this triangular O ring groove calculator during early layout work, quotation reviews, or tolerance checks. It is also helpful for comparing alternate groove angles. A narrower angle may increase fill at the same depth. A wider angle may reduce fill and create more cavity space. The calculator makes those tradeoffs visible in seconds.
This tool is best for estimation and design comparison. Final sealing dimensions can depend on material hardness, pressure, temperature, fluid compatibility, surface finish, and manufacturing tolerances. Always compare the result with your seal standard, supplier data, and application limits. Even so, this page gives a fast and structured way to analyze groove depth, width, squeeze, and fill in one place.
It estimates triangular groove depth, top width, gland area, actual fill, and a simple volume check using seal size, squeeze, angle, mean diameter, and stretch.
Squeeze shows how much the seal compresses after installation. Too little squeeze may leak. Too much squeeze can increase wear, friction, and assembly force.
Gland fill is the percentage of groove area occupied by the installed seal cross section. It helps show whether the groove has enough free space.
When the seal stretches around a diameter, its material redistributes. That reduces effective cross-sectional area in this simplified constant-volume estimate.
The comparison shows whether your chosen groove angle can satisfy the requested squeeze and fill at the same time. It is a fast design consistency check.
Yes, but use one unit system consistently for every input. The formulas are geometric, so the output stays consistent when all values use the same unit.
No. Use it for estimation, comparison, and early design review. Final release should also consider tolerances, material data, pressure, and application standards.
The note explains whether the selected angle needs a deeper or shallower groove to reach the requested fill target while keeping the current squeeze approach.
