What is the difference between Neoprene and Polyurethane (PUR) bodies?

The rubber body is the heart of the seal.

• Neoprene: Has excellent resistance to seawater and UV. Its elasticity allows the socket to expand and seal repeatedly (500+ cycles) without permanent deformation (Compression Set).
• Polyurethane: While less flexible, it acts like “armor.” It is ideal for the cable jacketing and the molded boot area to prevent cuts from sharp rocks or corals during operation.
• Bonding: Our Hochtemperatur-Vulkanisierung ensures both materials chemically bond to the metal shell, creating a watertight unibody.
