Direct answer

What this result means

Calculate O-ring cross-section squeeze and squeeze percentage from free cross-section and installed groove depth. The relationship S = (d2 − H) / d2 × 100% ties o-ring cross-section and installed groove depth directly to the reported result. The installed cross-section height equals the entered groove depth. Treat the value as a transparent preliminary calculation, then compare it with the actual cable-entry assembly and current product documentation.

Formula & theory

Make the assumptions visible.

S = (d2 − H) / d2 × 100% defines the calculation shown here. The installed cross-section height equals the entered groove depth. Keep the entered units with the result so another reviewer can reproduce the method.

Calculation relationship
SO−ring=d2−Hgd2 100%S_{\mathrm{O-ring}}=\frac{d_2-H_g}{d_2}\,100\%

S = (d2 − H) / d2 × 100% defines the calculation shown here. The installed cross-section height equals the entered groove depth. Keep the entered units with the result so another reviewer can reproduce the method.

Variables

Use sequence

From measurement to review

  1. Confirm o-ring cross-section and installed groove depth from a controlled drawing, measurement or project document.
  2. Apply S = (d2 − H) / d2 × 100% with consistent units and keep the entered values beside the result.
  3. Use cross-section squeeze only after checking O-ring standard, tolerances, stretch, material, temperature and the product-specific housing table.

Limits

What this calculation does not confirm

  • The installed cross-section height equals the entered groove depth.
  • Inputs describe one defined operating or measurement condition and use mutually consistent units.
  • The result does not by itself confirm product suitability, standards compliance, ingress performance or installation approval.

Calculator FAQ

Use the number without losing the engineering context.

These answers clarify what the tool calculates and where a product-specific review still begins.

01Calculator guidanceHow does the o-ring squeeze percentage calculator calculate cross-section squeeze?

The tool applies S = (d2 − H) / d2 × 100% to o-ring cross-section, installed groove depth. The installed cross-section height equals the entered groove depth. Keep the displayed units with the result so the calculation can be repeated.

02Calculator guidanceWhat does cross-section squeeze show for this seal squeeze review?

Calculate O-ring cross-section squeeze and squeeze percentage from free cross-section and installed groove depth. It is a preliminary engineering value, not confirmation of a cable-gland model, standards compliance or installation approval.

03Calculator guidanceWhat should be checked about O-ring standard before using the o-ring squeeze percentage calculator result?

The equation does not model O-ring standard, tolerances, stretch, material, temperature and the product-specific housing table. Confirm those conditions against the actual cable-entry assembly, applicable requirement and current product documentation.
