Si Tech Silicone Neck Seal - Small
By Si Tech | Part #: S61631 | Size: Small (22 - 30 cm) | Material: Hypoallergenic Silicone
Upgrade your drysuit comfort and reliability with the Si Tech Silicone Neck Seal in Small (Part #S61631). Constructed from 100% hypoallergenic medical-grade silicone, this replacement seal offers 40% greater stretch than traditional latex, providing a plush, skin-friendly fit for divers with smaller neck circumferences while completely eliminating latex allergy concerns.
Available at International Diving Centre—Vancouver’s local drysuit repair and equipment specialist—silicone seals are 100% UV and ozone resistant, meaning they won't degrade, crack, or become sticky over time. Note: Silicone seals cannot be glued directly to drysuits and are designed for use with modular quick-change neck ring systems.
Neck Ring Compatibility & Sizing
- Modular Quick-Change Fitting: Designed to snap directly into SI Tech Quick Neck, ORUST Neck System, and Neck Tite modular ring systems.
- Neck Circumference Fit: Small size fits neck circumferences from 22 cm to 30 cm (8.6" - 11.8").
- Trim-to-Fit Ridges: Features molded guide ribs so you can easily trim the opening for a customized, pressure-free neck seal.
