Inflatable Gasket Sizing
Reference guide for selecting inflatable gaskets for brewery tanks, fermenters, and pressure vessels. Match your tank lid diameter to the correct gasket size.
What Are Inflatable Gaskets?
Inflatable gaskets (also called inflatable seals) are hollow rubber or vinyl gaskets that inflate with air pressure to create a secure, leak-tight seal on tank lids, manways, and pressure vessel hatches. When deflated, the lid opens easily for cleaning and inspection. When inflated, the gasket expands to press firmly against the sealing surface.
🔒 Pressure-Tight Seal
Creates reliable seal for pressurized tanks and fermenters when inflated
⚡ Easy Access
Deflate to open lid without removing clamps or hardware
🔨 Quick Maintenance
Fast opening and closing speeds up cleaning and inspection cycles
💰 Cost Effective
Less expensive than mechanical locking systems for tank access

How to Measure for Inflatable Gaskets
Measure Tank Lid Diameter
Measure the outer diameter of your tank lid or manway opening in inches or centimeters.
Match to "Fits Tank Lid" Column
Find your measurement in the "Fits Tank Lid" column of the appropriate table (rubber or vinyl).
Note the Gasket Diameter
The corresponding gasket diameter (in cm) is the size you need to order.
Verify Groove Dimensions
Ensure your lid has an appropriate groove or channel to accommodate the inflatable gasket.
Installation & Maintenance Tips
Installation
- Clean the groove - Remove any debris, old gasket material, or residue before installing new gasket
- Seat properly - Ensure gasket is fully seated in the groove around the entire circumference
- Check inflation valve - Verify valve is accessible and properly oriented before closing lid
- Test inflation - Inflate gasket before pressurizing tank to verify it seals correctly
- Use appropriate pressure - Don't over-inflate. Typically 5-15 PSI is sufficient for sealing
Maintenance
- Deflate before opening - Always fully deflate gasket before attempting to open tank lid
- Inspect regularly - Check for cracks, tears, or wear. Replace damaged gaskets immediately
- Clean after use - Wipe gasket with mild cleaner. Avoid harsh chemicals on vinyl gaskets
- Protect from UV - Store tanks indoors or cover outdoor vessels to prevent UV degradation
- Keep spare gaskets - Stock common sizes to avoid production delays from gasket failure
- Check valve function - Test inflation valve periodically to ensure it holds pressure
Common Issues & Solutions
⚠ Gasket Won't Hold Air
Causes: Puncture, tear, or damaged valve
Solution: Submerge inflated gasket in water to locate leak. Small punctures can sometimes be patched, but replacement is usually more reliable.
⚠ Lid Still Leaks When Inflated
Causes: Under-inflation, debris in groove, damaged sealing surface
Solution: Increase inflation pressure slightly. Clean groove thoroughly. Inspect lid sealing surface for damage.
⚠ Gasket Difficult to Remove
Causes: Not fully deflated, stuck to groove
Solution: Ensure complete deflation. Use small amount of food-grade lubricant if gasket is stuck. Don't force removal.
⚠ Gasket Degrading Quickly
Causes: Chemical exposure, UV damage, over-inflation
Solution: Switch to black rubber for chemical resistance. Protect from sunlight. Use proper inflation pressure.
