What the AI looks for in Industrial Seals

Motion type: Static joint calls for a gasket or O-ring. Rotating shaft calls for a radial lip seal or, on pumps, a mechanical seal. Reciprocating rod calls for U-cups and wipers. Seal families are designed for one kind of motion, and using the wrong family is the most common cause of early leaks.
Exact dimensions: Measure shaft or rod diameter, housing bore and groove width with calipers, or read the code printed on the old seal. Seals work on a precise interference fit, and close-enough sizing leaks or overheats.
Elastomer and fluid compatibility: Use NBR for mineral oil and grease, FKM/Viton for heat and fuels, EPDM for water, steam and glycol (never with petroleum oils), and PTFE for aggressive chemicals. An incompatible elastomer swells, hardens or cracks within weeks.
Temperature and pressure: Check the rating against the worst-case operating temperature and pressure, not the normal running value. Peaks are what extrude or harden the seal.
