Alligator Valve Selection Process and Verification of Proper Assembly Fit
Internal Visual Inspection of the Wheel or Rim
1. Confirm location of drop-center:
• Is it nearer to front or back side of the wheel? –
• If near front, use the strap mount sensor.
• If near back, continue.
2. Confirm location of the valve:
• Is it beside the drop-center well, but at no more than a 10-degree angle? –
• If more than 10-degrees, use the strap mount sensor.
• If close, then continue.
3. Confirm diameter of valve hole in the wheel:
• Is it 0.453” (11.6MM)?
• [The only next closest standard sizes are 0.327” (8.38MM) and 0.625” (16.03MM)] –
• If smaller/larger, use the strap mount sensor.
• If confirmed 0.453” (11.6MM) diameter, then continue.
4. Confirm available clearance for the valve attachment nut:
• Is there 0.625” (16MM) diameter?
• [This clearance is adequate in most cases, but there are some wheels in the market where
we have found the anchor nut and washer to be 0.060” (1.5MM) too large.] –
• If less, then use the strap mount sensor.
• If more, then continue.
