Direct answer

What this result means

Calculate nominal, minimum and maximum seal squeeze from cross-section and groove-depth tolerances. The relationship Smin = [dmin − Hmax] / dmin ties nominal seal section, section tolerance, nominal groove depth and depth tolerance directly to the reported result. Entered tolerances are symmetric positive magnitudes. Treat the value as a transparent preliminary calculation, then compare it with the actual cable-entry assembly and current product documentation.

Use sequence

From measurement to review

  1. Confirm nominal seal section and section tolerance from a controlled drawing, measurement or project document.
  2. Apply Smin = [dmin − Hmax] / dmin with consistent units and keep the entered values beside the result.
  3. Use minimum squeeze only after checking tolerance conventions, coating, thermal change, material swell and the approved squeeze window.

Limits

What this calculation does not confirm

  • Entered tolerances are symmetric positive magnitudes.
  • 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 seal compression tolerance stack calculator calculate minimum squeeze?

The tool applies Smin = [dmin − Hmax] / dmin to nominal seal section, section tolerance, nominal groove depth, depth tolerance. Entered tolerances are symmetric positive magnitudes. Keep the displayed units with the result so the calculation can be repeated.

02Calculator guidanceWhat does minimum squeeze show for this squeeze tolerance review?

Calculate nominal, minimum and maximum seal squeeze from cross-section and groove-depth tolerances. It is a preliminary engineering value, not confirmation of a cable-gland model, standards compliance or installation approval.

03Calculator guidanceWhat should be checked about tolerance conventions before using the seal compression tolerance stack calculator result?

The equation does not model tolerance conventions, coating, thermal change, material swell and the approved squeeze window. Confirm those conditions against the actual cable-entry assembly, applicable requirement and current product documentation.
