Tips for Adjusting an Overly Tight Neck Gasket

Stretch the Gasket
New neck gaskets are often very tight. You can gently stretch them using items like a large coffee can or a mixing bowl. Leave the gasket stretched overnight or for a day or two. This usually helps loosen it while maintaining its seal.

Carefully Trim the Gasket
If stretching doesn't solve the issue, you can carefully trim the neck gasket. Most gaskets have rings or lines that act as guides to ensure an even cut. Trim one ring at a time and test the fit—it's always better to cut gradually since trimming cannot be undone.

Use Talcum Powder for Lubrication
Applying talcum powder to the gasket can make it easier to slide on and reduce friction around the neck, improving overall comfort.

Adapt to a New Dry Suit
Wearing a new dry suit might feel a bit tight initially. If you're certain the tightness isn't hazardous, try wearing it at home for short periods to get used to the pressure. However, if you experience dizziness or difficulty breathing, the gasket is too tight and needs further adjustment.
