Select an O-ring size, material, and sealing condition to get recommended static gland dimensions — Parker O-Ring Handbook, Section 4.
All gland dimensions, groove widths, squeeze percentages, and clearances in this tool are transcribed directly from Parker Hannifin Corporation, O-Ring & Engineered Seals Division, "Parker O-Ring Handbook" (ORD-5700) — Section 4 — Static O-Ring Sealing (Design Charts and Tables 4-1 through 4-7, pages 4-2 through 4-25) for the "Static Glands" tab, and Section 5 — Dynamic O-Ring Sealing (Design Charts and Tables 5-1 through 5-5, pages 5-15 through 5-44) for the "Dynamic Glands" tab. See the full document: ORD-5700.pdf.
The "Static Glands" tab covers seals with no relative motion between the sealed parts. The "Dynamic Glands" tab covers reciprocating (hydraulic and pneumatic), rotary, and dynamic vacuum seals, where one surface moves relative to the O-ring — these use different gland tolerances, clearances, and surface-finish requirements than static glands, and the two are not interchangeable.
Unlike the static section, the handbook does not publish a silicone/fluorosilicone clearance-derating rule for dynamic glands, so this tool does not apply any automatic dimensional adjustment based on material in the "Dynamic Glands" tab. Section 5 does note that nitrile (Buna-N) is generally preferred for reciprocating seals where extrusion resistance and wear resistance are priorities, and that rotary seals require a compound specifically developed for rotary service — consult the source PDF's material discussion before finalizing a dynamic seal design.
Parker's static gland dimensions are largely independent of elastomer compound, with one documented exception: the handbook states that when using silicone or fluorosilicone O-rings, published diametral/radial clearances should be reduced 50%. This tool applies that adjustment automatically when those materials are selected. No other material-specific dimensional guidance is published in this section — material choice elsewhere (chemical compatibility, temperature range, compression set) is outside this tool's scope.
This dataset was transcribed from scanned PDF table images. While every effort was made to reproduce values exactly as printed, always cross-check critical dimensions against the source PDF before cutting metal — especially for tight-tolerance aerospace (AS5857) applications.
This tool is for educational and preliminary reference only. For flight hardware, pressure-critical, or safety-critical applications, consult the current Parker O-Ring Handbook revision and qualified engineering analysis.
