SIFLEX SILICONE NECK SEAL

The Siflex silicone neck seal is a high-quality replacement neck seal commonly used on drysuits. Here are the key details:

Features

• Material: 100% medical-grade silicone – soft, flexible, and hypoallergenic (no latex allergies).

• Comfort: More comfortable and less constrictive compared to traditional latex seals.

• Durability: Resistant to UV light, ozone, and environmental degradation (does not become sticky or brittle like latex).

• Stretch: High elasticity allows for a snug but comfortable fit, reducing water ingress.

• Maintenance: No talc needed; silicone does not require the same care as latex.

Compatibility

• Designed to fit drysuits with a quick-change neck system (e.g., Si Tech Quick Neck or similar modular systems).

• Cannot be glued directly to a drysuit like latex seals — must be used with the proper modular ring system.

Sizes

• Generally available in Standard and Small sizes.

• The cone design allows trimming to achieve the best fit.

Advantages over Latex

• Longer lifespan (if not cut or punctured).

• Consistent flexibility in both warm and cold conditions.

• Comfortable for divers with sensitive skin or latex allergies.
